Is the original premise of project management software still the driving force? Is the critical path calculation still what makes projects run? Perhaps the entire industry has moved on.
Project management comes in all kinds of shapes and sizes but nowhere is scheduling more tightly managed than in a high-pressure shutdown/maintenance project. In these 5-10 day projects, an entire industrial facility must be stopped, have maintenance done and then restarted and ever hour that passes is huge amounts of money lost in production. It’s a particular kind of scheduling from which anyone in project management can learn a lot.
