Study Notes
Software Development Life Cycle (SDLC)
- SDLC is a structured process used to design, develop, test, and deliver high-quality, maintainable software that meets user requirements.
- SDLC consists of defined stages/phases to design, develop, and maintain software.
SDLC - Planning and Analysis
- In this stage, gather business requirements from clients/stakeholders.
- Evaluate the feasibility of the software project, considering cost and benefits.
- Once the project aligns with requirements and is feasible, proceed to the next phase (detailing requirements).
SDLC - Define Requirements
- This critical stage transforms gathered requirements into clear requirements for the development team.
- Resolves ambiguities (doubts) related to the software.
- Creates software requirement specifications (SRS) documents for customers, used in system design.
SDLC - System Design
- SRS documents serve as input for software design.
- Create flowcharts to illustrate software responses to user actions.
- Prototypes may be developed to visualize the product's appearance.
SDLC - Development
- Development team divides the project into modules and translates software requirements into code creating the product.
- This phase needs specialized development tools such as Computer Aided Design (CAD), Product Lifecycle Management (PLM), Computer Aided Engineering (CAE), Product Data Management (PDM), and Simulation and Prototyping Software.
- Tool selection depends on experience and available features.
SDLC - Test, Deploy, and Maintain
- Quality assurance team performs validation to ensure software functions correctly according to specifications (SRS).
- Final software deployment occurs through User Acceptance Testing (UAT) with users.
- Software is approved for "go-live" if customer validation is satisfactory.
- Maintenance is a further improvement stage of the software.
Software Engineering Process
- Plan-driven processes involve pre-planning all process activities. Progress is tracked against the plan.
- Agile-driven processes plan incrementally and adapt easily to changing customer requirements.
- There's no single "right" software process.
Software Development Process Models
- Waterfall Model: One of the earliest models.
- Phases: requirements definition, system design, implementation & testing, integration & testing, operation & maintenance.
- Output of one stage is input to the next.
- Requires extensive documentation.
- Simple and easy to use for projects with well-understood requirements, and where changes are unlikely.
- Can be more complex and costly when requirements change.
- V-Shaped Model: Similar to waterfall but verification and validation steps happen simultaneously in parallel. Early planning of testing is key.
- Advantages: Simple, easy to understand, systematic, high-quality products.
- Disadvantages: Not good for large projects where requirements change, very high costs when changes are made later.
- Prototype Model: A working model of a system is developed and refined and repeatedly tested with customer feedback until an acceptable prototype is achieved. This is useful when customer requirements are not well-defined.
- Advantages: Customer can see partial product early in the life cycle. Accommodates changing requirements. Errors are detected early.
- Disadvantages: Can be costly and time-consuming. Poor documentation. Uncertainty in the number of iterations.
- RAD (Rapid Application Development) Model: An incremental model with a very short development cycle.
- Breaks down project into smaller modules that can be developed by separate teams.
- Advantages: Powerful tools, short time spans, higher productivity, potentially faster
- Disadvantages: High skilled professionals needed, costlier than traditional models. Project leader needs strong teamwork and communication skills for success.
- Reuse-Oriented Model: Integrates systems from existing components (Commercial-off-the-shelf or COTS systems).
- Stages: component analysis, requirement modification, system design with reuse, development & integration, system validation
- Scrum Model: An agile process model for complex projects.
- Roles: Product Owner, Scrum Master, Development Team.
- Key elements: Product Backlog, Sprints, Product Increment.
- Advantages: Fast product delivery, customer satisfaction focus, improved collaboration.
- Disadvantages: Resource intensive due to continuous meetings and reviews, needs clear requirement definition early on.
Integrate Security into SDLC
- Traditional SDLC treated security as a separate step.
- Modern SDLC (DevSecOps) integrates security throughout the entire process to build "Secure-by-Design" systems.
- Security must be accounted for in all phases (planning, requirements definition, software design, software coding, and testing/software validation).
