Shade in se réfère-t-il au fait de colorier, ou quelque chose comme ça? Il s'agit en effet d'un exercice sur un diagramme graphique, donc...

"Once the boxes are drawn shade in the critical path."

ConTEXTE:

Now plot the start and finish times of each task. Remember that the earliest start time on the network describes the end of that day so we recommend that you add one to the earliest start time to get the actual start date. The end date is correctly shown on the network.
Once the boxes are drawn shade in the critical path.
Then add the total float bars for those activities not on the critical path.
For those tasks that have free float put an F over the total float bar for the appropriate number of units.
