Analysis of assumptions
Planning a site

The schedule indicates that the duration of the worksite is 43 working days. It would be interesting to reduce the duration to 8 weeks, or 40 working days, i.e. 8 × 5 days. This would make it possible to avoid starting a week with just 3 working days, as the last two might not be worked.

Reducing the total duration of the project by 3 days means finding critical tasks whose duration could be reduced, since they determine the overall duration of the project.
