Build Quality In
Building Quality In refers to the process of ensuring quality from the beginning of the software development process, rather than treating it as an inspection process at the end. This means incorporating various testing strategies, code reviews and best practices from the outset of development. By doing this, problems and bugs can be identified and addressed earlier in the process, making them easier and cheaper to fix. This practice promotes the idea that everyone on the team is responsible for quality, not just testers or quality assurance teams.
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.
