Gantt Charts
I think they are great, as a guideline, but lay out a project plan in a Gantt chart over a 6 month period and then compare what you planned against what happened…
I like them in small timeboxes, as guidelines, generalizations without fine levels of detail. Nothing beats a whiteboard when you are in the trenches.
Otherwise, I just have not seen them be terribly accurate in real world situations.
I mention this because it came up today in conversation.
I have weird conversations, I guess.
Best,
Josh
