Section 1
You cannot unknow what you know
Watch a technical founder explain their product to a finance director. Within a minute the sentence contains three terms that mean something precise internally and nothing outside: the ingestion layer, the reconciliation step, idempotency. Each is the right word. None of them is available to the listener. The founder is not showing off. They are describing the thing as they hold it in their head, which is the only way they have of describing it accurately. That is why advice to be less technical does not work. It asks for a translation without supplying one. What works is deciding in advance which three terms this audience needs, defining each in one sentence when it first appears, and refusing the rest. Precision without vocabulary is possible, it just has to be planned. Communicating under constraint to mixed audiences is also the problem in [Storytelling for Social Impact Entrepreneurs](/blog/storytelling-for-social-impact-entrepreneurs).
Section 2
Function before mechanism
Technical people explain in build order, from the foundation upward, because that is how the thing was made. Listeners need the opposite order. Tell them what it does and who stops having a bad day, and only then how it does it. Build order forces the audience to hold several unexplained components in memory before learning why any of them exist. Function order gives them a container to put each new detail into. It is the same content and roughly the same length. The difference in comprehension is large, and it costs nothing but sequencing.
Section 3
The analogy contract
Every analogy leaks. State the leak out loud when you use it: this behaves like a queue at a counter, except that anyone can rejoin at the front. Naming the limit is what stops a helpful comparison becoming a wrong belief you have to undo later. Explaining under pressure has its own dynamics, covered in [Storytelling as a Tool for Mental Wellness in High-Stress Roles](/blog/storytelling-as-a-tool-for-mental-wellness-in-high-stress-roles).
Section 4
Explaining to a mixed room
A typical evaluation meeting contains a finance lead, a security reviewer, and an engineer, and all three are assessing different risks. The instinct is to prepare three decks. The better approach is one story told at three depths. Layer one is a single sentence, mechanism-free, describing the change in outcome: the finance close takes two days instead of nine. Layer two is the mechanism in plain English, three or four steps, no product names. Layer three is the technical detail, offered rather than delivered, so the engineer can pull on it and the others can stop listening without missing anything. Sequencing matters. Start at layer one for everyone. If you open at layer three, the finance lead has disengaged before the outcome arrives, and you will not get them back.
Section 5
Where simplification becomes misrepresentation
There is a line, and technical audiences police it. Removing detail is fine. Removing a condition is not. If the result holds only for structured data, or only above a certain volume, that constraint is part of the claim and not an implementation detail to be mentioned during procurement. The second failure is the analogy that survives past its usefulness. Once a customer believes your system works like a spreadsheet, every subsequent conversation is spent correcting the model you gave them. The third is confidence about behaviour under conditions you have not tested. Where the system needs a human check, say so in the story rather than in the contract. That boundary is the whole subject of [Automated Decision-Making: Where to Draw the Line](/blog/automated-decision-making-where-to-draw-the-line).
