Animation of a planning
The following slides contain an animation of the planning of a list of activities.
First, you will see a network diagram
Followed by a calculation of the critical path and
Finally, a drawing of a Gantt chart.
Click to go to the next step of the schedule.
This example is about the installation of a central heating system that uses a boiler and hot water to distribute the heat.
Durations are in days.
Activities provided str beyond discussion.
Estimate the total duration first.
This animation is part of the book Project Management written by Roel Grit and published by Wolters-Noordhoff
