📖 What is Sequential Development Model?
A Sequential Development Model is an SDLC approach where each phase of the development process must be completed before the next one begins. The V-model and Waterfall model are classic examples, characterized by their linear progression and distinct, non-overlapping stages.
"Remember that in sequential models, test planning and test design should start as early as possible (e.g., during requirements analysis), even though test execution happens later."

🎯 How does Sequential Development Model appear on the CTFL-v4.0 Exam?
A scenario where test execution must wait until coding is complete.
Questions about when test planning starts in a V-model (during early phases).
❓ Frequently Asked Questions
What is a major disadvantage of sequential models?
They offer limited flexibility to adapt to changing requirements once a phase is complete.
When does test execution happen in a sequential model?
Test execution typically happens late in the cycle, after the coding phase is complete.
