🏡 “What to do? → Tasks” means:
Before you put dates in Microsoft Project, you must list all work that must be done.
In construction, this is your task list or WBS — Work Breakdown Structure. Your post says a schedule must answer: What to do, When to do, and Who does it; if one is missing, the schedule fails. (Sarim-insight)
Example in Microsoft Project:
Project: House Construction
Main task: Foundation
Small tasks:
Site clearing
Excavation
Rebar preparation
Formwork
Concrete pouring
Curing
Inspection
So “What to do?” is not “Foundation” only. It must be broken into clear action tasks.
A good rule from your post:
If one task is more than 3 days, break it smaller. (Sarim-insight)
Why? Because small tasks are easier to control.
Bad task:
Build structure
Better tasks:
Column rebar → Column formwork → Column concrete → Beam formwork → Slab rebar → Slab concrete
In Microsoft Project, each task should have:
Task Name = What work
Duration = How long
Start/Finish = When
Predecessor = What comes before
Resource/Responsibility = Who does it
Simple meaning:
Tasks = the real work on site.
No clear tasks = no clear schedule.
No clear schedule = hard to control workers, materials, delay, and progress.
