The Consulting Business Model

Use a diagnostic-led commercial model from first problem through implementation and expansion.

Find business problem → diagnose → quantify → recommend → implement → expand.

Stage	Output
Find	A consequential problem with an identifiable buyer
Diagnose	Evidence of what happens, why it matters and why it persists
Quantify	Transparent assumptions about value and cost
Recommend	A prioritised first intervention
Implement	A bounded production scope and delivery owner
Expand	Adjacent projects, recurring work or referrals justified by evidence

A paid diagnostic should create value even if implementation does not proceed. It also gives both sides a lower-risk way to decide what should be built first.
