“Fit out the villa” is not a task. It is an outcome. As a single line on a plan it tells you nothing useful — you cannot price it, sequence it, or tell how far through it you are. The work of breaking a job down is the work of turning outcomes into pieces you can actually see and move.
There is no single correct way to do it. There are three honest ways, and most good plans use all of them at different levels.
Three ways to split a fit-out job
-
By room or zone
The most natural cut for fit-out. “Master bedroom”, “reception”, “main lobby”, “core corridor”. Each zone is a place you can walk to and stand in, which makes progress visible in a way no spreadsheet can match.
-
By trade
“Joinery”, “MEP first fix”, “marble and stone”, “painting and finishing”, “joinery second fix”. Trade cuts line up cleanly with subcontractors and with the BOQ, which is why procurement and the QS prefer this view.
-
By phase
“First fix”, “second fix”, “snagging”, “handover”. Phase cuts track the lifecycle of the job and are how the programme is usually built.
None of these is more correct than the others. A good breakdown uses all three: phases at the top, rooms or zones in the middle, trades at the bottom. The shape that matters is that every piece is small enough to track.
When to stop splitting
This is the question every foreman asks, and the answer is simpler than people expect. You stop splitting when one person can finish the piece in a few days.
A piece that passes this test has three properties, all of them useful. You can estimate it without guessing. You can tell whether it is done without a debate. And when it slips, you know within days rather than discovering it a month later when the whole programme has quietly moved.
Going finer than this is a mistake. A plan made of one-hour tasks looks impressive and collapses the first time anything changes. The point is legible progress, not exhaustive detail. A joinery package for one villa, broken into wardrobe, doors, and vanity, each with its own estimate, is trackable. The same package split into a hundred individual screw-holes is noise.
There is a quick way to sense whether you have split well. Walk the plan with someone who was not in the room when you wrote it. If they can tell you, for each line, roughly what is done and what is not, the split is right. If they have to ask what a line means, it is either too big or too vague — and both have the same fix.
Why a task nobody can estimate is not yet understood
Estimation is treated like a skill — as though some people are simply good at putting durations on things. It is not. Estimation is a test of understanding.
When nobody on the team can put a number on a task, it is almost never because the task is hard to estimate. It is because the task is not really a task. It is a bundle of smaller things hiding behind one vague word, and until you open the bundle nobody can see what is inside.
“Sort out the MEP” cannot be estimated because it is not one thing. Break it into electrical first fix, HVAC ducting, plumbing rough-in, low-current containment, and testing and commissioning, and a competent person can put a duration on each. The estimate appears the moment the understanding does.
What this looks like in Taskity
Every job has a tree of tasks underneath it, and the tree can be cut by room, by trade, or by phase — usually all three, at different levels. The one-person-few-days test is the rule of thumb the system expects you to follow when you add a task. When a task has no estimate, that is treated as a signal to break it further, not as a box to fill in with a guess.
Check what you learned
1. You split "fit out the villa" into "ground floor" and "first floor". Each is still three months of work and nobody can say how far along it is. What is the real problem?
Show the answer
The pieces are still too big to measure, so progress stays a guess
Splitting by floor is a perfectly good first cut. The problem is that the pieces are still too large to track — three months of mixed work behind one label gives you no measurable progress, which was the whole point of breaking it down. The fix is to keep splitting until each piece is small enough that "is it done?" has an honest yes-or-no answer. The count of pieces matters less than their size.
2. A task on your list reads "sort out the MEP". Nobody can give you a duration for it. What does that tell you?
Show the answer
The task is not yet understood and needs to be broken down further
Estimation is a test of understanding, not a test of skill. When nobody can put a duration on a task, it is because the task is really several tasks bundled under one vague word. "Sort out the MEP" hides electrical first fix, HVAC ducting, plumbing rough-in, and so on — each of which a competent person *can* estimate. Break it until each piece is estimateable, and the durations will appear on their own.
