TIP: Search out ScrumMasters from other organisations – ideally those that are the most different from yours and share experiences. User groups are a good start but great ScrumMasters usually establish more focused relationships such as ScrumMaster circles. These circles are usually no larger than six people who meet up either face-to-face or virtually on a regular basis to discuss their latest challenges or thoughts. Perhaps you could even try a ScrumMaster exchange program—swap a ScrumMaster with another company for a retrospective, or even a whole sprint?
