Software Development Life Cycle
Definition
The Software Development Life Cycle (SDLC) is a process used by the software industry to design, develop, and test high-quality software. The SDLC aims to produce high-quality software that meets or exceeds customer expectations, reaches completion within times and cost estimates.
Why It Matters
An SDLC provides a structured framework for a software project. It defines the phases and tasks involved, helping to ensure that the project is managed effectively and that the end product is well-engineered.
Contextual Example
A typical SDLC includes phases like: 1. Planning and Requirement Analysis, 2. Defining Requirements, 3. Designing the Product Architecture, 4. Building or Developing the Product, 5. Testing the Product, and 6. Deployment and Maintenance.
Common Misunderstandings
- Agile and Waterfall are two different types of SDLC methodologies.
- The SDLC applies to the entire lifetime of a software product, from initial idea to end-of-life.
