Study Notes
Software Development Life Cycle (SDLC)
- SDLC is a time-efficient process used by development teams to design and build high-quality software that meets customer expectations.
- It minimizes project risks through forward planning and ensures that all stakeholders agree on software development goals and requirements upfront.
Importance of SDLC
- SDLC provides a systematic management framework with specific deliverables at every stage of the software development process.
- It helps manage software development challenges, such as changing requirements, technology upgrades, and cross-functional collaboration.
Benefits of SDLC
- Increases visibility of the development process for all stakeholders.
- Enables efficient estimation, planning, and scheduling.
- Improves risk management and cost estimation.
- Ensures systematic software delivery and better customer satisfaction.
Phases of SDLC
Planning
- Includes tasks like cost-benefit analysis, scheduling, resource estimation, and allocation.
- Development team collects requirements from stakeholders to create a Software Requirement Specification (SRS) document.
- SRS sets expectations and defines common goals that aid in project planning.
- Identifies and defines the problem, and researches the scope of the problem.
Requirement Analysis
- Information about each element to design, validating installation, calibrating security protocols, and risk analysis.
- Creates a software requirement specification document.
Design
- Software engineers analyze requirements and identify the best solutions to create the software.
- Considers integrating pre-existing modules, making technology choices, and identifying development tools.
- Integrates the new software into existing IT infrastructure.
- Creates a system design following the SRS, and shares it with stakeholders for review.
Implement
- Development team codes the product based on the design document.
- Analyzes requirements to identify smaller coding tasks.
- Writes code using languages, and implements the software product.
Deploy
- Develops software in a separate build environment, different from the production environment.
- Sets up an installation link for users, and debugs the application on a regular basis.
- Provides regular updates with new features.
- Ensures customers can continue to use the software while it is being changed or upgraded.
- Includes tasks like packaging, environment configuration, and installation to move the latest build copy to the production environment.
