Five roles, the test each applies and the evidence placing each person there: a buying center map for DDBA 8531 in Week 2 lays out all three for one purchase. Searches like "ddba 8531 week 2 assignment example", "ddba8531 week 2 sample" and "ddba 8531 week 2 example" land here.
What a finished DDBA 8531 Week 2 buying center map looks like
A one-page table and three pages of commentary. Rows are participants by function: bedside nurses, the biomedical engineering manager, the clinical informatics lead, the supply chain director, the value analysis committee, the chief financial officer, and a department administrator who controls vendor access. Columns give the Webster and Wind role, the test applied, veto power, and the evidence for the assignment, such as committee minutes, a job posting or an interview. Tests are concrete: nurses judged programming steps and alarm behavior, biomedical engineering judged service terms, informatics judged whether the pumps talk to the medication record. Commentary follows in three parts: where roles overlap, where power differs from title, and which participant the seller met least often. A small diagram shows who talks to whom.
How a DDBA 8531 Week 2 example is structured
The table is built before the commentary, and each row must earn its evidence cell, so a participant placed by assumption is flagged as an inference rather than presented as fact. Roles are assigned by what a person did in this purchase, not by job description, which is why the informatics lead appears as an influencer with a practical veto. Bonoma's argument that buying power often sits somewhere other than where the organization chart suggests frames the second commentary section, and the map tests it against the minutes: the committee decided formally, but informatics had already removed two models. Overlap is treated as information, since one person holding two roles changes the number of meetings a seller needs. The final section names the least-visited participant and says what that neglect would cost.
Participants by function
Seven rows, from bedside nurses to the department administrator who books vendor visits. Functions replace names so the map can be shared, and the list is built from minutes and interviews rather than from the organization chart alone.
A test for every row
Programming steps for nurses, service terms for biomedical engineering, interface with the medication record for informatics, contract price for supply chain, the capital budget line for finance. Each test is stated as the question that participant raised.
Formal authority and practical power
The value analysis committee approved the purchase; informatics had already narrowed the field to one model. The veto column records both facts, which is where Bonoma's argument about hidden buying power stops being abstract.
Evidence in every placement
Committee minutes, a posted job description, a conversation with the biomedical engineering manager. Placements without a source are marked as inferences, which shows anyone reading the map where better information would change it.
The participant the seller missed
The department administrator controlled which vendors reached the floor for demonstrations. The commentary names that role as the least visited and explains how one missed scheduling contact delayed the trial by a month.
Where marks go in DDBA 8531 Week 2
Evidence for each placement carries the heaviest weight, because a map without it is a guess drawn neatly. Graders read the tests next and reward the ones stated as questions a real participant asked, programming steps or service response time, over labels such as quality or cost. The veto column earns credit when it separates formal authority from practical power and says where the two diverge. Bonoma is credited when the commentary uses his argument to explain a specific mismatch in this purchase. Common deductions: a gatekeeper omitted because nobody thought of the administrator who schedules vendor visits, users collapsed into one row when different shifts judged differently, and a decider identified by seniority alone. The diagram is optional in most sections; the evidence column is not.

A role table with an evidence column, the commentary and a small influence diagram are drafted inside 24 to 48 hours, at no cost the first time. Placements the sample cannot support from sources are labeled as inferences, not asserted.
DDBA 8531 Week 2 questions, answered
Can one person hold more than one buying center role?
Often, and the map should show it. A department head may be both user and decider, and a procurement officer may act as buyer and gatekeeper. Recording the overlap matters because it changes the sales effort: fewer people to persuade, but each with more at stake. Creating an extra participant just to fill an empty role is less accurate than admitting the overlap.
Where does evidence for the map come from?
Meeting minutes and approval records where they are public, interviews where they are not, and job descriptions for what each function normally controls. Public institutions such as hospitals, school districts and utilities often publish committee materials. Where you rely on your own experience, say so, and mark any placement you could not confirm as an inference.
Is Webster and Wind's five-role model still current?
It remains the standard starting point, and later textbooks and research have extended it rather than replaced it, adding roles such as initiator and approver and paying more attention to power. Using the five roles as columns keeps the map readable. Where your purchase does not fit them neatly, the commentary is the place to say which role the model misses.
