Further detail
The SDLC is also known as software development models, software development process models, or software development methodologies.
The SDLC ensures systematic development, quality standards, risk reduction, resource optimization, and alignment with business goals within a reasonable timeframe.
Picture the SDLC as a living organism progressing from inception to retirement.

What does the Software Development Life Cycle (SDLC) describe?
The typical phases and progression between phases in software development.
What are the main purposes of the SDLC?
To deliver reliable software, avoid pitfalls, and keep projects on schedule.
What are the seven phases in a common SDLC model?
Planning, analysis, design, coding, testing, deployment, and maintenance.
How do predictive and Agile SDLC models differ in phase completion?
Predictive models complete phases sequentially; Agile models use iterative and incremental development.
What is the Waterfall Model in software development?
A linear sequential predictive model with no phase overlap or return.
Which phases does the Waterfall Model proceed through?
Requirement analysis, system design, implementation, integration and testing, deployment, and maintenance.
It covers the core concepts of SDLC Models, organized by topic with the key definitions, explanations and takeaways, so it's easier to learn and remember.
