The series on maintaining a project plan and Gantt chart in Excel has been popular, and I've had a lot of queries about tracking progress. So, in this bonus post I’ll describe how to display tasks’ progress on the Gantt chart that was featured in the previous posts in this series. In addition, I’ll show how to highlight “today”. Alongside this paragraph (right) you can see what the result of this post looks like.
Let’s start by inserting a column after E and heading it “%Done”. This is where you'll need to type values to indicate your progress. Then, after column N let’s add “Done” and “DoneEnd”. I’ve made the text colour of the latter two columns a semi-visible grey because they’re our working values and not of interest to the reader of the Gantt chart. If you see the picture below, you’ll see that I’ve also populated the %Done column with some values.
Now let’s populate the calculated columns. The working columns are not strictly necessary, but they’ll help illustrate the calculations that we’re doing. Firstly, let’s understand what we’re trying to achieve. Cell H3 represents progress on activity #1 on day 1. We’ll display a block in the cell if progress on the activity is equal to (or greater than) half a day’s effort. So, for activity #1 we can see that effort is complete up to the end of day 3; for activity #2 the effort is complete up to 2/3 of the way through day number 2. Since day number 2 for activity #2 is more than half complete we’ll put a block in that cell (but not day number 3).
