(a) Define project. Explain need of software project management.
In software engineering, a project refers to a planned and structured process of developing a software system. It involves identifying the user’s requirements, designing the software, writing the code, testing the software, and deploying it. A project typically involves a team of people working together towards a common goal within a specific timeline and budget.
Software project management is the process of planning, organizing, and managing resources to bring about the successful completion of a software project. The primary goal of software project management is to ensure that the software project is completed on time, within budget, and meets the user’s requirements.
The need for software project management arises because software development is a complex process that involves multiple phases and stakeholders. Without proper management, software projects are prone to fail due to a lack of clarity in requirements, poor communication among team members, lack of proper planning, insufficient resources, and changes in requirements during development. Therefore, software project management is crucial for the successful completion of a software project. It helps in coordinating the efforts of team members, ensuring that they work towards a common goal, and monitoring progress to ensure that the project is on track.
(b) Describe seven steps involved in project planning.
Project planning is a critical phase in software project management that involves identifying and defining project objectives, deliverables, milestones, and deadlines. Here are the seven steps involved in project planning:
- Defining Project Objectives: The first step is to define the project’s objectives, including the desired outcome, scope, and constraints. The project manager should create a clear and concise statement of the project’s goals.
- Identifying Deliverables: The project team should identify the deliverables that will be produced as part of the project. Deliverables are the tangible or intangible items that will be produced as a result of the project.
- Developing the Work Breakdown Structure (WBS): A work breakdown structure (WBS) is a hierarchical decomposition of the project into manageable tasks. The WBS defines the project’s scope, provides a roadmap for project execution, and facilitates communication among team members.
- Identifying Dependencies: The project team should identify the dependencies between tasks and determine the order in which they should be executed. Dependencies can be categorized as mandatory, discretionary, or external.
- Estimating Resource Requirements: The project manager should estimate the resources required to complete each task, including personnel, equipment, and materials. This information is used to create a detailed project schedule.
- Developing the Project Schedule: The project schedule is a timeline that outlines the start and end dates for each task. The project manager should consider constraints such as resource availability and budget limitations when developing the project schedule.
- Identifying Risks: The project team should identify potential risks that could impact the project’s success. This includes technical risks, resource risks, and external risks. A risk management plan should be developed to mitigate and manage these risks.
(c) Explain types of WBS structure with diagram and advantages.
Work Breakdown Structure (WBS) is a hierarchical decomposition of the entire project scope into smaller, more manageable work components. It helps in breaking down the complex project into smaller and easily manageable tasks. There are two types of WBS structures:
- Deliverable-Oriented WBS: This WBS structure is organized based on the project deliverables or end products. It is also known as product-based or outcome-oriented WBS. In this structure, the project is broken down into deliverables that are then further broken down into smaller tasks.
Advantages of Deliverable-Oriented WBS:
- Helps in focusing on the deliverables of the project.
- Provides a clear understanding of what is expected from the project.
- Enables project teams to identify dependencies between deliverables and tasks.
Example of Deliverable-Oriented WBS:
- Phase-Oriented WBS: This WBS structure is organized based on the project phases. It is also known as a process-based or activity-oriented WBS. In this structure, the project is broken down into smaller phases, and each phase is further divided into activities or tasks.
Advantages of Phase-Oriented WBS:
- Provides a clear understanding of the project phases and activities.
- Helps in identifying project risks and critical path activities.
- Helps in tracking project progress.
Example of Phase-Oriented WBS:
Both WBS structures have their own advantages and disadvantages, and the choice of WBS structure depends on the project type and requirements.
(a) Define Project Scheduling. Explain how project scheduling play important
role in project success
Project scheduling refers to the process of creating a plan that outlines the sequence of tasks, milestones, and deadlines required to complete a project. It involves determining the timeframes for each activity, estimating the duration of each task, and developing a project timeline.
Effective project scheduling plays a crucial role in project success by helping to ensure that the project is completed on time and within budget. It helps project managers to:
- Identify project tasks and their dependencies: Project scheduling helps to identify the sequence of tasks required to complete the project and the dependencies between them. This helps project managers to better understand the scope of the project and to develop a realistic timeline.
- Estimate project duration: Project scheduling helps to estimate the time required to complete each task, which helps to identify the critical path and determine the overall project duration.
- Allocate resources: Project scheduling helps to allocate resources effectively by identifying the tasks that require specific resources and scheduling them accordingly.
- Monitor progress: Project scheduling provides a basis for monitoring project progress by providing a baseline for comparison with actual performance. This allows project managers to identify potential issues and take corrective action to keep the project on track.
- Identify potential risks: Project scheduling helps to identify potential risks and allows project managers to develop strategies to mitigate them.
- Communicate with stakeholders: Project scheduling provides a tool for communicating project timelines and milestones to stakeholders, which helps to manage expectations and build trust.
(b) List types of activities covered by software project management. Explain
any two in detail.
Software project management covers a wide range of activities from project planning to project closure. Some of the key activities covered by software project management are:
- Project planning and scheduling
- Requirements analysis and management
- Risk management
- Resource management
- Team management
- Quality management
- Configuration management
- Stakeholder management
- Project monitoring and control
- Project closure
Two activities that can be explained in detail are requirements analysis and management, and risk management.
- Requirements analysis and management: This activity involves identifying, analyzing, documenting, and managing the requirements of the software project. It includes understanding the needs of the stakeholders, translating them into specific requirements, and managing changes to the requirements throughout the project lifecycle. Requirements analysis and management ensure that the project delivers the desired functionality, meets the needs of the stakeholders, and achieves the project objectives.
- Risk management: This activity involves identifying, analyzing, and managing the risks that can impact the project’s objectives. It includes identifying potential risks, assessing their impact and probability, developing risk mitigation strategies, and monitoring and controlling the risks throughout the project lifecycle. Risk management helps in identifying and addressing potential problems early, ensuring that the project stays on track, and reducing the likelihood of project failure. It also helps in identifying opportunities that can be leveraged to improve the project’s outcome.
(c) Explain PERT with suitable example.
PERT stands for Program Evaluation and Review Technique, which is a project management tool used to analyze and represent the tasks involved in completing a project. It helps in identifying the critical path, the sequence of tasks that must be completed on time in order to ensure the completion of the project on schedule.
Here is an example to explain PERT:
Suppose a company is developing a software product and the project is divided into the following tasks:
- Task 1: Requirements gathering
- Task 2: Design and architecture
- Task 3: Development and coding
- Task 4: Testing and debugging
- Task 5: Deployment and maintenance
For each task, we estimate the optimistic (O), pessimistic (P), and most likely (M) duration of completion. Using these estimates, we can calculate the expected duration (E) of each task using the formula E = (O + 4M + P)/6.
Suppose the estimates for each task are as follows:
- Task 1: O = 3 weeks, M = 4 weeks, P = 5 weeks
- Task 2: O = 4 weeks, M = 5 weeks, P = 6 weeks
- Task 3: O = 6 weeks, M = 8 weeks, P = 10 weeks
- Task 4: O = 2 weeks, M = 3 weeks, P = 4 weeks
- Task 5: O = 1 week, M = 2 weeks, P = 3 weeks
Using these estimates, we can construct a PERT network diagram, which shows the dependencies between tasks and the expected duration of each task. The diagram is shown below:
3 4 Task 1 --> Task 2 --> Task 3 --> Task 4 --> Task 5 4 5 8 3 2
The numbers above each arrow represent the expected duration of the task. The critical path, which is the path with the longest expected duration, is Task 1 → Task 2 → Task 3 → Task 4 → Task 5, with an expected duration of 22 weeks. Any delay in completing any of these tasks will cause a delay in the completion of the entire project.
PERT helps in identifying the critical path and allows project managers to focus on these tasks and ensure that they are completed on time. It also helps in identifying the tasks that can be delayed without affecting the project completion time, and in estimating the overall time and cost of the project.
(c) Illustrate the use of Gantt Chart for project scheduling with example
A Gantt chart is a popular tool used in project management to visualize the timeline of a project. It shows the start and end dates of individual tasks, as well as their dependencies and how they overlap with other tasks.
Here is an example of how a Gantt chart can be used to schedule a project:
Suppose a company is planning to develop a new software product. The project has been divided into six major phases: Planning, Design, Development, Testing, Deployment, and Maintenance. Each phase has several subtasks that need to be completed before the next phase can begin. The estimated duration and dependencies of each task are as follows:
- Conduct market research (3 weeks)
- Define product requirements (2 weeks)
- Obtain funding (1 week)
- Develop UI wireframes (2 weeks)
- Create detailed design documents (4 weeks)
- Get design approval (1 week)
- Code the front-end (6 weeks)
- Code the back-end (8 weeks)
- Integrate front-end and back-end (2 weeks)
- Develop test cases (2 weeks)
- Conduct functional testing (4 weeks)
- Conduct system testing (6 weeks)
- Prepare for launch (2 weeks)
- Conduct user acceptance testing (3 weeks)
- Launch the product (1 week)
- Provide user support (ongoing)
- Fix bugs and issues (ongoing)
To create a Gantt chart for this project, we can use a software tool or create it manually using a spreadsheet or paper. The Gantt chart will have a horizontal axis showing the timeline of the project, broken down into weeks or days. The vertical axis will show the list of tasks, arranged in the order of the project phases.
For example, the Gantt chart for this project may look like this:
In this Gantt chart, each task is represented by a horizontal bar that spans the duration of the task. The dependencies between tasks are shown by arrows that connect the bars. For example, the “Define product requirements” task in the Planning phase must be completed before the “Develop UI wireframes” task in the Design phase can begin, so there is an arrow between them.
The Gantt chart allows project managers to see the overall timeline of the project, identify critical paths, and monitor progress. By adjusting the start and end dates of tasks, project managers can also simulate different scenarios and determine the impact on the project schedule.
(a) Explain SCM with its advantages.
SCM stands for Software Configuration Management, which is a process that helps to identify, organize and control the changes made to software products during the software development life cycle. SCM involves the management of the entire software development process, from requirements gathering to testing and delivery. It includes tools and techniques for managing changes, controlling versioning, and tracking defects in software products.
Advantages of SCM are:
- Improved Productivity: SCM provides a structured approach to software development which helps to improve productivity. It provides tools to track changes, version control, and code reviews which help to identify and fix issues quickly, saving time and effort.
- Quality Assurance: SCM ensures that the software product meets the required quality standards. The process ensures that all changes made to the software are reviewed and tested before they are integrated into the product. This helps to identify and fix defects early in the development process, which reduces the likelihood of errors in the final product.
- Better Collaboration: SCM promotes collaboration between team members, allowing them to work together more efficiently. It provides a central repository for all project files, allowing developers to easily access and share code, documents, and other project files. This improves communication and reduces the risk of misunderstandings.
- Risk Reduction: SCM helps to reduce the risk of software failure by identifying and fixing issues early in the development process. The process ensures that changes are carefully reviewed and tested before they are integrated into the product. This helps to identify and fix defects early, reducing the likelihood of issues in the final product.
(b) Explain an effective strategy for dealing with Risk in Project
Risk management is a crucial aspect of project management, and an effective strategy can help a project manager to mitigate risks and ensure project success. Here is an effective strategy for dealing with risks in project management:
- Identify Risks: The first step is to identify potential risks that could impact the project. Project managers can use various techniques, such as brainstorming, checklists, and risk assessment templates to identify risks.
- Analyze Risks: After identifying risks, the next step is to analyze them. This involves assessing the likelihood of the risk occurring and the potential impact it could have on the project. Project managers can use techniques such as risk probability and impact analysis to analyze risks.
- Develop Response Strategies: Once the risks have been identified and analyzed, the next step is to develop response strategies. There are four possible responses to a risk: Avoid, Transfer, Mitigate, and Accept. Project managers need to develop response strategies for each risk.
- Implement Response Strategies: The next step is to implement the response strategies. This involves taking action to avoid, transfer, mitigate, or accept the risks. Project managers need to ensure that the response strategies are integrated into the project plan and that they are executed as planned.
- Monitor Risks: After implementing the response strategies, the project manager needs to monitor the risks. This involves tracking the progress of the response strategies and identifying any new risks that may arise. Project managers should regularly review the risk management plan and make adjustments as necessary.
The advantages of this strategy are:
- It helps project managers to identify potential risks that could impact the project.
- It provides a structured approach to analyzing and managing risks.
- It helps project managers to develop effective response strategies for each risk.
- It ensures that response strategies are integrated into the project plan and are executed as planned.
- It enables project managers to monitor risks and make adjustments as necessary, which helps to mitigate risks and ensure project success.
(c) Explain various risk management activities in detail.
Risk management is an essential activity in project management to ensure project success. The following are the different risk management activities:
- Risk Identification: This is the first step in risk management, where all possible risks that can occur in the project are identified. The risks can be identified by various methods, such as brainstorming, checklists, historical data, etc.
- Risk Analysis: After identifying the risks, the next step is to analyze them in detail to determine their probability of occurrence and their impact on the project objectives. This helps in prioritizing the risks and developing appropriate strategies to manage them.
- Risk Evaluation: In this step, the risks are evaluated to determine whether they can be accepted, transferred, mitigated, or avoided. The evaluation is based on the risk tolerance level of the organization and the project stakeholders.
- Risk Mitigation: This step involves developing strategies to reduce the impact and probability of occurrence of the identified risks. The strategies can include risk avoidance, risk transfer, risk acceptance, and risk reduction.
- Risk Monitoring: Risk monitoring is an ongoing process that involves tracking and reviewing the identified risks throughout the project life cycle. This helps in identifying new risks and monitoring the effectiveness of the risk management strategies.
- Contingency Planning: In this step, contingency plans are developed to deal with the identified risks. The contingency plans should be developed for high-risk events that have a significant impact on the project objectives.
- Risk Reporting: Risk reporting is an essential activity that involves communicating the identified risks, their impact, and the risk management strategies to the project stakeholders. The risk reporting should be done on a regular basis to keep the stakeholders informed about the project risks and their status.
(a) Describe risk components and risk drivers
In project management, risk components refer to the elements that contribute to the risk of a particular project. These can include a variety of factors such as technical complexity, market volatility, regulatory compliance, team dynamics, and more.
On the other hand, risk drivers are the specific events or circumstances that trigger a particular risk. These can include external factors such as changes in market conditions or government regulations, as well as internal factors such as resource constraints or technical issues.
Identifying and managing both risk components and risk drivers is critical for effective risk management in project management. By understanding the underlying factors that contribute to risk and the events that trigger it, project managers can take proactive steps to mitigate risk and ensure project success.
(b) Why Earned Value Analysis is needed in project management? Explain
features provided by EVA.
Earned Value Analysis (EVA) is a widely used tool in project management that helps to track project performance and measure progress. It provides a systematic approach to measure project progress and enables project managers to identify potential problems and take corrective actions to stay on track.
EVA is needed in project management for the following reasons:
- Performance measurement: EVA provides a framework for measuring project performance, by comparing the actual work done with the planned work and the cost incurred.
- Early warning system: EVA identifies potential problems early in the project lifecycle, enabling project managers to take corrective actions before they become critical.
- Decision-making: EVA provides project managers with the information they need to make informed decisions about the project, such as whether to continue with the current plan, or make changes to the plan to improve project performance.
The features provided by EVA include the following:
- Planned Value (PV): The amount of work planned to be completed at a specific point in time, according to the project schedule.
- Earned Value (EV): The value of work actually completed at a specific point in time.
- Actual Cost (AC): The actual cost incurred to complete the work at a specific point in time.
- Schedule Variance (SV): The difference between the planned value and the earned value, indicating whether the project is ahead of or behind schedule.
- Cost Variance (CV): The difference between the earned value and the actual cost, indicating whether the project is under or over budget.
- Schedule Performance Index (SPI): The ratio of earned value to planned value, indicating the efficiency of the project schedule.
- Cost Performance Index (CPI): The ratio of earned value to actual cost, indicating the efficiency of project cost management.
(c) Explain configuration management process in detail.
Configuration Management (CM) is a process of tracking and controlling changes made to the software products throughout its lifecycle. It involves identifying, organizing, and controlling modifications that occur in the software products, documentation, and artifacts produced during the development process. The main aim of configuration management is to ensure the accuracy, consistency, and completeness of the software products and to manage changes in a systematic manner.
The Configuration Management Process consists of the following steps:
- Planning: The planning phase involves identifying the configuration items (CIs) and defining the procedures for managing them. The configuration management plan (CMP) is created, which outlines the scope of the CM process, the organizational structure, and the roles and responsibilities of the team members.
- Identification: In this phase, all the configuration items are identified and documented. This includes software, hardware, documentation, and other related items. Each item is assigned a unique identifier, which is used to track changes throughout the development process.
- Control: Once the configuration items have been identified, they are placed under control. This involves creating a baseline of the software product and all its associated artifacts, which is used as the reference point for all subsequent changes. The baseline is maintained and controlled through the use of version control tools, which enable team members to track and manage changes made to the software.
- Status Accounting: Status accounting involves tracking and reporting the status of the configuration items throughout the development process. This includes information on the current version of the software, the changes made, and the individuals responsible for making those changes. This information is used to ensure that the software product is developed according to the requirements and that any issues or problems are identified and resolved in a timely manner.
- Auditing: Auditing involves reviewing the configuration management process to ensure that it is being followed correctly. This includes reviewing the documentation, reviewing the changes made to the software, and verifying that the baseline has been properly maintained. Auditing helps to identify any issues or problems with the configuration management process and enables the team to take corrective action.
- Release Management: Release management involves planning, coordinating, and controlling the release of the software product to the end-users. This includes ensuring that the software product meets the requirements of the end-users, that all documentation and user manuals are complete, and that the software is ready for deployment.
Some of the advantages of Configuration Management are:
- Consistency: Configuration Management ensures consistency throughout the development process by providing a baseline for all changes made to the software product. This helps to ensure that the software product is developed according to the requirements and that all changes are properly documented and controlled.
- Traceability: Configuration Management provides traceability of all changes made to the software product. This includes information on who made the changes, what changes were made, and when they were made. This helps to identify any issues or problems that may arise during the development process.
- Control: Configuration Management provides control over the development process by ensuring that all changes are properly documented and controlled. This helps to ensure that the software product is developed according to the requirements and that any issues or problems are identified and resolved in a timely manner.
- Collaboration: Configuration Management enables team members to work collaboratively on the development process by providing a central repository for all changes made to the software product. This helps to ensure that team members are working together effectively and that all changes are properly documented and controlled.
(a) Briefly explain important SQA attributes.

- Audits: It is the process of examining and evaluating the software development process and its deliverables to ensure that they meet the pre-defined quality standards and requirements.
(b) Discuss approach of risk categorization.
Risk categorization is the process of organizing risks into different categories based on their common characteristics. This approach is helpful in identifying and prioritizing risks, and allocating appropriate resources for their management. There are different approaches to risk categorization, but the following are the common ones:
- Source-based approach: This approach categorizes risks based on their source or origin. Risks can be grouped into categories such as technical risks, project risks, external risks, and business risks.
- Impact-based approach: This approach categorizes risks based on their potential impact on the project. Risks can be grouped into categories such as low-impact risks, medium-impact risks, and high-impact risks.
- Probability-based approach: This approach categorizes risks based on their probability of occurring. Risks can be grouped into categories such as low-probability risks, medium-probability risks, and high-probability risks.
- Control-based approach: This approach categorizes risks based on the degree of control that the project team has over them. Risks can be grouped into categories such as controllable risks, partially controllable risks, and uncontrollable risks.
(c) Why are standards important for software? Briefly explain ISO standards
for software organization
Standards are important for software because they provide a set of guidelines and best practices for software development, which can help to ensure that software is reliable, secure, and of high quality. Standards can also help to improve the interoperability of software and facilitate communication between different organizations and systems.
ISO (International Organization for Standardization) has developed a number of standards for software organizations, including:
- ISO 9001: This is a quality management standard that outlines a set of requirements for the development and delivery of high-quality products and services. It can be applied to any type of organization, including software organizations.
- ISO/IEC 12207: This is a software life cycle standard that provides a framework for the development, operation, and maintenance of software. It covers all aspects of the software development process, from requirements analysis to testing and maintenance.

- ISO/IEC 27001: This is an information security standard that outlines a set of requirements for the establishment, implementation, and maintenance of an information security management system (ISMS). It can help software organizations to protect their intellectual property and ensure the confidentiality, integrity, and availability of their data.
(a) List various SQA activities and explain any one of them.
Software Quality Assurance (SQA) is a systematic approach to evaluate and monitor software engineering processes and ensure the quality of the software product. The following are some of the SQA activities:
- Reviews and Inspections
- Standards and Procedures
Reviews and inspections are an SQA activity that involves a systematic examination of a work product to find and correct defects. This activity is conducted by a group of people who are not involved in the development of the work product. The objective of this activity is to identify and correct defects early in the development cycle, which can save time and money.
The review process typically involves the following steps:
- Planning: Determining the scope of the review, selecting the participants, and scheduling the review.
- Kickoff meeting: Introducing the review team, establishing the ground rules, and reviewing the objectives and expectations of the review.
- Preparation: Participants independently review the work product to identify defects and make notes.
- Review meeting: Participants discuss and share their findings, identify defects and potential solutions, and document the review results.
- Rework: The author of the work product corrects the identified defects and resubmits the work product for a follow-up review if necessary.
- Follow-up: The follow-up review verifies that all the identified defects have been corrected.
(b) Write a short note on Project Status Report.
A project status report is a document that provides an update on the progress, issues, risks, and achievements of a project. It is typically prepared on a regular basis, such as weekly or monthly, and is distributed to stakeholders including project sponsors, project team members, and other interested parties. The purpose of the status report is to communicate the current status of the project, including any changes that have occurred since the last report, and to identify any issues or risks that may affect the project’s success.
The contents of a project status report may vary depending on the project and the audience, but typically include:
- Project summary: A brief overview of the project, including the project goals, timeline, budget, and key stakeholders.

(c) Explain Capability Maturity Model (CMM) in detail.
Capability Maturity Model (CMM) is a framework that provides a set of guidelines for improving the process of software development. It was developed by the Software Engineering Institute (SEI) at Carnegie Mellon University in the late 1980s. CMM defines a model of five levels of process maturity that a software organization can achieve.
The five levels of CMM are as follows:
- Initial: At this level, processes are ad-hoc and unstructured. There is no formal process or documentation, and success depends on individual effort and heroics.
- Repeatable: At this level, basic project management processes are established. The focus is on tracking cost, schedule, and functionality. The processes are repeatable and predictable.
- Defined: At this level, processes are well documented and standardized throughout the organization. The organization has a common understanding of the process and its goals. Process measurements are used to improve quality and productivity.
- Managed: At this level, the organization has a quantitative understanding of the process and can use data to control it. Statistical techniques are used to manage and improve the process.
- Optimizing: At this level, the organization continuously improves its processes using feedback from the process and its results. The focus is on continuous process improvement, innovation, and new technologies.
(a) Explain types of software maintenance services categories.
Software maintenance refers to the process of modifying, updating, and improving software to ensure that it continues to function correctly and meet user needs over time. The different types of software maintenance services categories are:
- Corrective Maintenance: This type of maintenance is performed to correct faults or defects in the software. Corrective maintenance is necessary to ensure that the software continues to function properly and meets the user’s needs.
- Adaptive Maintenance: This type of maintenance involves modifying the software to adapt it to changing environments, such as changes in hardware, operating systems, or user requirements.
- Perfective Maintenance: This type of maintenance is performed to improve the performance, efficiency, or maintainability of the software. Perfective maintenance involves modifying the software to enhance its functionality, improve its usability, or simplify its maintenance.
- Preventive Maintenance: This type of maintenance is performed to prevent future problems from occurring in the software. Preventive maintenance involves identifying potential problems and taking steps to prevent them from occurring.
(b) Discuss project closure analysis report in detail with sample example.
Project closure analysis report is a document that summarizes the results and achievements of a project. It is an important document that provides valuable insights into the performance of the project team and the project as a whole. The report includes a review of the project’s goals, objectives, activities, and outcomes. It is used to evaluate the project’s success and to identify areas for improvement in future projects.

The project closure analysis report provides valuable insights into the project’s performance, lessons learned, and recommendations for future projects.
(c) Explain different phases of software maintenance process with figure.
Software maintenance is the process of modifying and updating software applications to correct errors, improve performance, and enhance features. The maintenance process is divided into several phases, which are explained below:
- Problem identification: This phase involves identifying the issues or problems with the software application that need to be addressed. These issues can be identified through user feedback, testing, or system logs.
- Analysis: In this phase, the identified problems are analyzed to determine their root cause. The analysis helps in understanding the scope of the problem and identifying the resources required to address it.
- Design: In the design phase, a plan is developed for addressing the identified problems. This includes defining the changes that need to be made, documenting the modifications, and developing a test plan.
- Implementation: The implementation phase involves making the changes to the software application. This can include updating the code, modifying the database, or changing the user interface.
- Testing: After the changes have been implemented, the software is tested to ensure that it is functioning correctly. This includes functional testing, regression testing, and system testing.
- Deployment: Once the testing phase is complete, the updated software is deployed to production. This includes installing the new software, updating the documentation, and training the users.
- Evaluation: In the evaluation phase, the effectiveness of the maintenance process is evaluated. This includes analyzing the cost and time required to complete the maintenance activities, measuring the impact of the changes on the system, and collecting feedback from users.
(a) State objective of closure analysis report.
The objective of a closure analysis report is to evaluate the outcome of a completed project and document the lessons learned during the project lifecycle. The report aims to assess the success or failure of the project, identify areas for improvement, and provide recommendations for future projects. It also serves as a tool for knowledge transfer from one project team to another, helping to avoid similar mistakes and pitfalls in future projects. The closure analysis report should provide a comprehensive overview of the project, including its objectives, scope, timeline, budget, resources used, and outcomes achieved.
(b) Explain various steps involved in Business Process Re-engineering.
Business Process Re-engineering (BPR) is the radical redesign of business processes to achieve dramatic improvements in performance, quality, and service. The steps involved in BPR are:
- Identify processes for redesign: The first step in BPR is to identify the processes that need to be redesigned. This can be done by analyzing the business objectives, customer needs, and performance metrics.
- Understand existing processes: Once the processes have been identified, the next step is to understand the existing processes. This involves mapping out the current processes, documenting them, and analyzing them.
- Analyze the current processes: After understanding the existing processes, the next step is to analyze them. This involves identifying the inefficiencies, bottlenecks, and other areas for improvement.
- Design new processes: Based on the analysis of the existing processes, new processes need to be designed. The new processes should be designed to eliminate inefficiencies, reduce cycle time, and improve overall performance.
- Implement new processes: Once the new processes have been designed, they need to be implemented. This involves training employees, updating policies and procedures, and integrating new technology.
- Monitor and evaluate: The final step in BPR is to monitor and evaluate the new processes. This involves tracking performance metrics, identifying areas for improvement, and making necessary adjustments.
(c) Explain software Re-engineering process model.
Software re-engineering is the process of renovating, upgrading or restructuring an existing software system to make it more maintainable, efficient, and cost-effective. It involves understanding the existing software system and modifying its structure and functionality to meet new requirements or adapt to changing technology.
The software re-engineering process model includes the following steps:
- Requirements Analysis: The first step is to identify the problems or limitations of the existing software system and gather the new requirements. The requirements analysis process involves identifying stakeholders, understanding the business processes, and defining the functional and non-functional requirements.
- Reverse Engineering: Reverse engineering is the process of extracting information from the existing software system to understand its structure, design, and functionality. The main goal of reverse engineering is to create a high-level abstraction of the software system, including its components, relationships, and behavior.
- Restructuring: Once the requirements and existing software system have been analyzed, the next step is to restructure the system by modifying or replacing its components. The restructuring process involves identifying the modules to be modified, redesigning the software architecture, and implementing the new components.
- Forward Engineering: Forward engineering is the process of creating a new software system from the modified or restructured components. The forward engineering process involves designing the new system, coding, testing, and implementing the new system.
- Testing: Testing is an important part of the software re-engineering process. The testing process involves verifying the new software system to ensure that it meets the new requirements and performs as expected. The testing process includes unit testing, integration testing, system testing, and acceptance testing.
- Maintenance: Once the new software system has been deployed, it is important to maintain it to ensure that it continues to meet the requirements and remains up-to-date with changing technology. The maintenance process involves monitoring the system, fixing bugs, updating software components, and adding new features.
