Decision Making Unit
What is a DMU?
- The group of people who jointly decide a single purchase
- Initiator, user, decision maker, gatekeeper, etc.
- Identify each role and engage accordingly
Working with the DMU in mind changes the unit of sales from a person to a group. Progress is no longer measured by how many emails you have exchanged with one contact, but by how many people co-decide the deal and how many of them you have met in person. Instead of one proposal, you prepare versions for the business unit, finance, and procurement. And meeting requests change from 'whenever suits you' to 'we would like to meet the two team leaders who will attend the training.'
Note that the number of roles does not equal the number of people. In a small company, one owner may be the initiator, decider, and buyer all at once, while a large enterprise may have more than five influencers alone. Counting only internal staff is not enough either: an incumbent training vendor, an HR consultant, or the group's talent development institute can be an external influencer who sets the criteria. The size also varies by buying situation. Renewing an annual course as-is takes just the manager and the procurement team, but a first-time program or a company-wide rollout multiplies the people involved and deepens the approval chain. Also check ahead of time whether crossing an approval threshold (commonly KRW 30 million (≈ US$22,400) or 50 million) adds an executive you have never met to the DMU.
The most common mistake in practice is mistaking the org chart for the DMU. A senior title does not make someone the decision-maker, and a junior associate who drafts the criteria may be the real influencer. The second is treating the gatekeeper as an obstacle and going around them. Skipping your contact to reach an executive directly often ends with 'why are you ignoring our process?' and a closed door. The third is betting everything on one friendly person. If they move roles in the year-end reshuffle, six months of work goes back to square one. Leaving opponents of the deal off the map is the same mistake.

The DMU traces back to the “buying center” concept that Frederick Webster and Yoram Wind introduced in 1972. It later became widely used in B2B marketing under the name “Decision Making Unit (DMU).”
Consider a hypothetical case. A proposal for a new team leader program at Company A, an auto parts manufacturer with 1,200 employees, had been stalled for four months. We had exchanged more than ten emails with the contact on the talent development team, but the only reply was “under internal review.” When we recounted the people involved from scratch, we found that six people were jointly deciding this one.
- Our first contact was Manager Kim on the talent development team. Kim reached out first, saying 'last year's team leader turnover was 18%,' but said plainly that they had no budget authority.
- Before resending the proposal, we asked, “How far up does approval for this go?” The answer: two levels, through the HR executive to the head of management support.
- We interviewed six team leaders in the production division, the actual training audience, for 30 minutes each. One said, “So I’m supposed to sit in a classroom again?” so we made half the program on-the-job assignments.
- Mr. Lee, a deputy general manager in procurement, looked only at unit prices and contract terms. We broke the KRW 30 million (≈ US$22,400) quote into a per-module price list and sent it back with two clauses, liquidated damages and early termination, already revised.
- For the HR executive, we cut the 45-page proposal down to a single A4 page and kept one line: 'Turnover down from 18% to 12%, saving KRW 140 million (≈ US$104,700) a year in replacement hiring costs.'
- The deal that had been stalled for four months cleared approval within two weeks of re-engaging. A single KRW 30 million (≈ US$22,400) proposal became a KRW 48 million (≈ US$35,900) annual contract bundling the team leader and part leader programs.
