Shift Left Quality Assurance: How to do it. Why it matters.
Download as PPTX, PDF3 likes3,992 views
The document discusses the 'shift left' approach in software testing, which emphasizes integrating quality assurance from the beginning of a project to reduce defects and costs. Key strategies include defining the testing lifecycle, leveraging trained testers, validating requirements, using formal test design techniques, and frequent process audits. By adopting this approach, organizations can enhance their testing maturity and deliver higher quality software more efficiently.

Are you ready for a “Shift Left”?
- 6. www.worksoft.com 6 Why “Shift Left” and striving for high maturity?
- 7. www.worksoft.com 7 Late defect discovery is expensive and disruptive!
- 8. www.worksoft.com 8 1. Define the Testing Lifecycle • Define full testing lifecycle with SDLC phases, activities, tasks, steps, roles, work products, templates, metrics, and tools • Move appropriate testing and QA activities to the initial project planning, requirements and design phases versus beginning these in the construction phase • Integrate the testing process with the PMO, development and enterprise architecture processes Steps to “Shifting Left” 2 Leverage professionally trained software testers and/or have current associates performing these roles get ISTQB certified (at least take the classes)
- 9. www.worksoft.com 9 3 Validate the requirements • Implement a formal inspection process to aid in early defect discovery • Dramatically reduce the construction phase with inspections that will remove ambiguous requirements and identify missing requirements • Inspections should initially be applied to requirements, functional design and technical designs. Later, this can be expanded to test plans, test cases, business models and source code. 4 Leverage formal Test Design Techniques • Implement and require the use of formal test design techniques like decision analysis, equivalence class partitioning and orthogonal analysis • Leveraging these techniques will ensure that you are writing the minimal number of test cases that will provide the broadest amount of functional coverage Steps to “Shifting Left”
- 10. www.worksoft.com 10 5 Govern both the process usage and process outputs (content evaluation) • Identify the critical phases, tasks and activities that need to be audited • Establish a formal compliance scorecard containing these critical activities • Conduct gating audits at the end of each SDLC phase • Report compliance to executive leadership team and take action on non-compliance Steps to “Shifting Left”
