The Method — Engineer

Common mistakes businesses make during engineer

The most expensive mistake in Engineer is accepting the first explanation that fits the mood of the room — and it is the one almost every owner makes, because the shortcut feels like competence.

These are the failures we see repeatedly in this specific phase. Later phases have their own; these belong to Engineer.

Each one produces the same symptom: the phase gets declared done and the constraint stays exactly where it was.

Step by step

  1. Assuming the answer before doing the work

    Accepting the first explanation that fits the mood of the room. The theory is usually reasonable and usually incomplete.

  2. Working from the numbers you like

    Selective evidence is the default failure mode of any owner examining their own business, and it is not a character flaw.

  3. Skipping the write-up

    A causal explanation the owner agrees with has to exist in writing or the next phase inherits a memory instead of an input.

  4. Letting the loudest person converge the phase

    Convergence should come from evidence. When it comes from seniority, the phase produced a preference.

  5. Rushing to feel productive

    Two to four weeks is normal. Compressing it moves the cost to a later phase where it is larger.

Common mistakes

Confusing this phase with the next one

Each phase has one job. Borrowing the next phase’s work is how both get done badly.

Declaring victory on a partial result

A phase is finished when its output exists and survives challenge, not when the calendar says so.
