Smartsheet's Error in % Complete Rollup
I recently realized that Smartsheet has a major flaw in rolling up % Completion.
In Smartsheet %complete for a Parent is calculated as a weighted average of %completion of the immediate children times the duration of the Parent. For example in the following Project, the overall % complete shows 50% where the correct % complete is 10%: Completed work (1 day) divided by total work (10 days) equals 10%.
In other words, task1 is overweighed and all subtasks under task 2 are underweighted.
I have escalated this to smartsheets and would like to share with the community as this could have serious impact if you are managing a complex project.
