6.1Why the First 90 Days Define Your Next 3 Years

The first 90 days in a new QA role are disproportionately important. In this window, you establish your reputation, build or destroy trust, demonstrate your value, and set the trajectory for your entire tenure. People form opinions about new hires in the first month, and those opinions become extremely difficult to change.

Most QA engineers start a new role and immediately try to fix everything they see wrong. This is the fastest path to failure. Before you can change anything, you need to understand the system -- the product, the people, the processes, and the history. The QA engineers who make the biggest long-term impact are the ones who spend the first 90 days listening, learning, and building relationships before they start proposing changes.

This file gives you a structured plan for each phase: the first 30 days (learn), the first 60 days (contribute), and the first 90 days (lead).
