Each loss looks reasonable at the moment it happens. From the inside it feels like a decision, not a mistake. Here are the four losses that Forma catches by its design, and the node responsible for each.
1. Generalization — Intent
It looks like a good analogy: “something like a dashboard” instead of a concrete image. The image blurs, and with it the thing by which the work is later accepted.
2. Omission — Spec
It looks like welcome brevity. Part of the task goes unwritten, and no one notices the loss until it is too late.
3. Distortion — Kit
It looks like a clever translation of intent into practice. When the task was turned into equipment, its kind changed unnoticed: they set out to do one thing and equipped for another.
4. Substitution — Run
It looks like resourcefulness when something is missing. The gap was filled with something similar, and the work moved on.
What links them: map and territory
Together, the four losses answer the question “the map is not the territory.” Arrival sign — the only point where the map (the task description) is tied to the territory (what must actually come out). While the sign is single and unambiguous, divergence is visible and measurable.
If the sign is removed, losses start to pile up undetected. Each step is small and plausible, and together they draw a map that leads to the wrong place. Arrival at the wrong place looks like arrival: all tasks are closed, all reconciliations passed, no one individually lied, and yet the result is wrong.
How to apply it in practice
- Write the readiness sign so that it admits only one reading.
- Check what distinguishes success from failure, not what they have in common.
- Do not accept work by impression: only by the written sign.
- Judge the whole separately from its parts: five passed checks say nothing about the thing as a whole.
