This metric shows the average number of hours of maker time (focus time that is spent on work without distractions like meetings, etc) by the user or the team. It also gives the percentage relative to the number of hours spent working and an indicator to show whether the user or team is getting sufficient maker time.
In other words: Maker time metric represents the distribution of the work day for your teams and their members by meeting v/s focus time availability. Focus time is the amount of time in a workday which is not spend in meetings. This is further broken down into
Maker time: Maker time is defined as continuous blocks of at least 120 minutes time during work hours where there are no meeting interruptions. Typically you should maximize the maker time for individual contributors to help them focus on delivery.
Fragmented time: Fragmented time is defined as gaps of less that 120 minutes between meetings. Typically you want to minimize this so that developers can have uninterrupted time for deep work and minimize loss of productivity due to context switching.
