The Method — Engineer

How engineer connects to the next phase of the method

Engineer hands the next phase exactly one thing: a causal explanation the owner agrees with. Build then takes a causal explanation the owner agrees with and uses it to do building the smallest thing that relieves the constraint and proving it works.

Published Growth-Scaling pricing and this topic’s row in Sitemap v9.

The phases are sequential because each one’s output is the next one’s input. That is the entire argument for the order.

Run out of sequence, the later phase substitutes an assumption for the input it never received — which is what the method exists to prevent.

Step by step

  1. What this phase produces

    A causal explanation the owner agrees with. One artifact, written, dated.

  2. Why the next phase cannot start without it

    It would have to invent the input. Invented inputs are indistinguishable from good ones until the results arrive.

  3. What gets lost when you skip ahead

    Accepting the first explanation that fits the mood of the room — and the cost surfaces two phases later, priced higher.

  4. How to tell the handoff was clean

    The next phase’s first meeting does not spend an hour re-deciding what this phase already settled.

  5. What comes after

    Build then takes a causal explanation the owner agrees with and uses it to do building the smallest thing that relieves the constraint and proving it works.

Common mistakes

Overlapping the phases to save time

The saving is real and the rework is larger. This is the most common process failure we see.

Handing over a conversation instead of a document

Verbal handoffs decay. By the next phase’s second week, two people remember it differently.

Frequently Asked Questions

How engineer connects to the next phase of the method?

The phases are sequential because each one’s output is the next one’s input. That is the entire argument for the order.

What should a business owner do with this before booking an Assessment?

It sits under The Engineer Phase in the Growth Scaling Method. The next step for an owner is the $1,500 Assessment, which reads your own numbers against everything described above.

What does working with Growth-Scaling cost?

Four thousand five hundred dollars for the Foundation, split evenly across three deliverables. Recurring work is quoted afterward and never starts below five thousand a month.

Who will we actually be talking to?

Both partners, on every engagement. That is the structural reason the firm stays small and the reason the engagement list is short.
