Study Notes
Software Development Life Cycle
Phases
Defining Phase
- Identify the problem or opportunity
- Define the project scope and goals
- Determine the feasibility of the project
Planning Phase
- Create a detailed project plan
- Establish timelines, budget, and resources
- Identify and mitigate risks
SDLC Activities
Requirements Gathering
- Collect and document user requirements
- Identify functional and non-functional requirements
- Develop a product backlog or requirement specification document
Requirements Engineering
- Analyze and prioritize requirements
- Develop a detailed requirement specification
- Validate and verify requirements
Design
- Create a detailed design of the software
- Develop architecture, component, and interface designs
- Create a prototype or mockup
Implementation
- Write the code for the software
- Develop and integrate individual components
- Conduct unit testing and integration testing
Testing
- Verify that the software meets the requirements
- Identify and fix defects
- Conduct various types of testing (e.g. unit, integration, system, acceptance)
Deployment
- Release the software to the production environment
- Configure the software for deployment
- Conduct post-deployment testing and verification
Maintenance
- Fix defects and make updates to the software
- Enhance and refine the software
- Provide ongoing support and maintenance
Documentation
- Create and maintain documentation for the software
- Develop user manuals and guides
- Update documentation to reflect changes and updates
Software Development Life Cycle
Phases
- The SDLC consists of Defining, Planning, and six other phases
- These phases are iterative and may overlap
Defining Phase
- Identify problems or opportunities to improve the software
- Determine project scope and goals
- Assess project feasibility to decide whether to proceed
Planning Phase
- Create a detailed project plan with timelines, budget, and resources
- Identify and mitigate risks to ensure project success
- Establish project scope, goals, and deliverables
SDLC Activities
Requirements Gathering
- Collect and document user requirements through surveys, interviews, and observations
- Identify functional and non-functional requirements, such as performance and security
- Develop a product backlog or requirement specification document
Requirements Engineering
- Analyze and prioritize requirements to ensure they meet user needs
- Develop a detailed requirement specification with clear and concise language
- Validate and verify requirements to ensure they are correct and feasible
Design
- Create a detailed design of the software, including architecture, components, and interfaces
- Develop a prototype or mockup to visualize the software
- Create a design document that outlines the software's structure and components
Implementation
- Write the code for the software, using programming languages and tools
- Develop and integrate individual components, such as modules and libraries
- Conduct unit testing and integration testing to ensure code quality
Testing
- Verify that the software meets the requirements and is free from defects
- Identify and fix defects, such as bugs and errors
- Conduct various types of testing, including unit, integration, system, and acceptance testing
Deployment
- Release the software to the production environment, ensuring it is stable and functional
- Configure the software for deployment, including setting up servers and databases
- Conduct post-deployment testing and verification to ensure the software meets user needs
Maintenance
- Fix defects and make updates to the software, ensuring it remains functional and efficient
- Enhance and refine the software, adding new features and functionality
- Provide ongoing support and maintenance, including troubleshooting and updates
Documentation
- Create and maintain documentation for the software, including user manuals and guides
- Develop documentation that is clear, concise, and easy to understand
- Update documentation to reflect changes and updates to the software
