Ultimately, I need a good way to track if we are completing tasks on time based on our original estimates because we have users that estimate a task will take 5 days and when it takes 15 they just change the dates, and the project status still looks green, when is reality it is behind.
I would like to have target start/end date columns that work exactly like the default Start Date & End Date columns, meaning I want the parent rows to populate based on the smallest date in the start column and the largest date in the end column.
I have also added a Health column to provide a visual of whether the task was completed on time or not. Here is the formula for that column, which seems to be working correctly. =IF(ISBLANK([End Date]@row - [Target End Date]@row ), "Gray", IF([End Date]@row - [Target End Date]@row >= 10, "Red", IF([End Date]@row - [Target End Date]@row <= 0, "Green", "Yellow")))
