Abstract

Does your team struggle to have enough time to test or to have enough depth in your automated tests? Problems here result in customers finding defects that the team missed. Different quality leadership personnel at Medidata have focused on either increasing automation or increasing exploratory testing.

In this discussion, I'll share my experiences on finding the right mix of automated and manual testing and how to know what to focus on for your project. This should help you make necessary adjustments to your current strategy and provide answers when leadership suggests a shift in focus. I'll also give tips to accomplish this shift and explain the "why" behind a test to maximize its value.

Key Takeaways

1. How to strike the right balance between automated and manual testing to minimize customer-reported defects.

2. Practical methods to adjust testing strategies based on project needs and priorities.

3. Insights into when to emphasize automation vs. exploratory testing for maximum impact.

4. Understand the “why” behind each test to ensure higher value, better coverage, and stronger product quality.
