SDLC: The Journey from Idea to Release
You now know who's on the team and how tasks move through a board. This module zooms out to the big picture: the full journey a piece of software takes from a rough idea to a live release — and back again.
This is where the "QA only tests finished code" myth finally dies.
What You'll Learn
- All six phases of the Software Development Life Cycle and what happens in each
- Why bugs caught early cost dramatically less than bugs caught late — and how this shapes your entire career strategy
- The key differences between Waterfall and Agile/Scrum methodologies
- QA's active role at every stage, not just the "Testing" phase
The Three Lessons
Lesson 1 — SDLC Phases: Six Steps to Success (Intermediate) From Requirements Analysis through Maintenance, you'll walk each phase step by step. The famous cost-of-defects model lives here — understanding it will change how you approach every project you ever work on.
Lesson 2 — Flexibility vs. Concrete: Agile/Scrum vs. Waterfall (Intermediate) Two philosophies, two very different outcomes. You'll understand when each approach makes sense, what Sprints and Retrospectives actually accomplish, and why most modern teams have chosen agility over the blueprint.
Lesson 3 — The QA Role at Every SDLC Stage The final lesson ties the entire course together. You'll see exactly how a QA engineer contributes from the very first requirements meeting through to post-release monitoring — and why "Shift Left Testing" is not just a buzzword but a career-defining principle.
