One task in ApuTime can have multiple solvers when more people collaborate on same thing. This possibility avoids duplicities between tasks. Documentation, history and conversation is on the same place to make your work more smoothly.
Each solver have their own Status and Estimate Time. We are focused on reflection reality as it is.
When somebody close the task it is only partially closed, because other solvers are still in progress.
Each solver have also estimate time which corresponds with their own workload. Total estimate time is calculated from all data depending on Work Sequence.
Work sequence means how solvers can work on task. Parallel and Serial work influences estimate time summaries.
In case of parallel work summary of estimate time is composed from two parts: the highest estimate time as task difficulty and sum of all estimates as man hours.
Whereas serial work is for both (task difficulty and man hours) same.
