Scrum is a lightweight process framework. As it is just a framework, you can find the same implementation in the world rarely. Even at the company level scrum implementation will be different project by project.
To validate our coaching effort we use Scrum Checklist (originally written by Henrik Kniberg). Henrik’s checklist is a paper-based survey easy to use during meetings. Coaches however need to validate more teams than just one with a lot of people. Agile at the enterprise level is more complicated. You need to apply the concept of a scrum etc.
We use Microsoft Excel files to validate teams. This survey is sent to all team members. They are encouraged to fill it separately. After that coaches process files and prepare an overview with Pivot charts. Additionally, the coach follows up with face-to-face meetings with all team members. This way the changes are gathered and coaches can focus on further improvements.
