Decision-making unit (DMU)

The people who decide, influence, use, pay for and can veto a purchase. Mapped as roles, dispositions and relationships, not job titles.

The decision-making unit is everyone on the customer side who shapes whether a proposition lands: the people who decide, who influence, who use, who pay, and who can quietly veto. In the method it is mapped as seven roles: buyer, user, specifier, influencer, gatekeeper, decider and sponsor, with the buyer at the centre. The map is many-to-many: one person can hold several roles, and one role can be shared. Job titles are a poor guide to either.

Two further axes make the map useful rather than decorative. Disposition, held separately from role: in favour, neutral or against. And the relationship matrix between the DMU and your own account team, which shows where the conversation is actually happening and where it is not. When a stakeholder changes role or leaves, a living plan flags which parts of the proposition are now exposed. A plan in a filing cabinet does not.
