Exam Guide: Build Quality In - Lean Software Development
What is Build Quality In?
'Build Quality In' is a core principle of Lean Software Development. It emphasizes the importance of minimizing defects and errors from the very beginning stages of a software project rather than catching them in later stages or after the software's release.
Why is 'Build Quality In' important?
Implementing 'Build Quality In' can significantly reduce the cost and time of software projects. Early defect detection can prevent wasteful spending on the rework and debugging of released software. The principle aims to produce a high-quality product from the start, leading to higher end-user satisfaction.
How does 'Build Quality In' principle work?
This principle works by integrating quality checks and testing in every development phase. This often involves practices like Test-Driven Development (TDD), Continuous Integration (CI), and automated testing. In turn, these methods lead to immediate feedback on software quality and faster identification and rectification of any emerging errors.
Exam Tips: Answering questions on 'Build Quality In'
1. Understand the underlining idea: It's about preventing defects rather than fixing them. Make sure you grasp this idea fully.
2. Be familiar with practices: Know how Test-Driven Development, Continuous Integration, and automated testing contribute to 'Build Quality In'.
3. Application is key: Examiners often look for understanding of the practical applications of 'Build Quality In'. Ensure you can provide examples of it being applied.
4. Keep cost and time in mind: Remember the impact 'Build Quality In' has on reducing overall project costs and development time.
