If you answer yes to any of the following, then you are ready:• Have you mastered the art of testing, but still failing to meet customers’
expectations?• Are you experiencing high requirements volatility in late stages of
development?• Is a majority of your defect discovery occurring in the “build/construction”
phase?• Is testing more than 25% of your overall project costs?• Are you struggling to deliver projects on time?• Are you striving to move to the next level of test maturity?
Are you ready for a “Shift Left”?

Why “Shift Left” and striving for high maturity?

Late defect discovery is expensive and disruptive!

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)

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

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
