Example: “One of the most valuable lessons I learned from a failed integration project was the importance of comprehensive stakeholder alignment before diving into development. In a previous project, we rushed into integrating a new CRM system without fully understanding the unique needs of different departments. This led to a lot of rework as various teams found that essential features they needed were either missing or implemented in a way that didn’t align with their workflows.

This experience taught me the necessity of investing time upfront for thorough requirements gathering and stakeholder engagement. Since then, I’ve made it a point to conduct detailed workshops and frequent check-ins with all relevant parties before and during the integration process. This approach has led to smoother rollouts and systems that truly meet the needs of all users, saving time and reducing frustration for everyone involved.”
