The HotSpot mobile app is a simple and effective way for group leaders to track and manage culture change. Using any set of data measurements, this app normalizes all relevant scores and creates an overall "HotSpot" score for every group in the organization. Rankings in the HotSpot scores list allow leaders to quickly see where problems need to be addressed, and take immediate action. Any leader wanting to implement change initiatives could benefit from the HotSpot mobile app.
