Development Life
Cycle
A comprehensive overview of the
process of creating software.

,Topics covered
Definition The Software Development Life Cycle (SDLC)
is a structured and systematic methodology used by the
software industry to design, develop, and test high-
quality software.
Primary Goal: To produce software that meets or
exceeds customer expectations, is delivered on time and
within budget, and is efficient and maintainable.
Key Idea: It provides a framework of best practices and
phases that guide developers and project managers
through the entire project from start to finish.

, Why is SDLC Important?
Provides Clear Structure: Offers a predictable roadmap for
the entire project, reducing confusion.
Improves Project Management: Enables better planning,
scheduling, and budgeting.
Enhances Quality: Early identification of issues and defined
checkpoints at each phase ensure the final product is robust.
Facilitates Communication: Standardized phases and
deliverables ensure all stakeholders (clients, developers,
testers) are on the same page.
Controls Costs: Finding and fixing defects early in the cycle
is significantly less expensive than fixing them after
deployment. Chapter 2 Software Processes 4
