Introduction

Earlier papers in this course traced how the vaccine launch team I lead developed and assessed its effectiveness, finding a weak structure, unclear norms and moderate psychological safety. This paper examines a single consequential decision: the first-year sales forecast and the production plan built on it. In November, the team agreed on a forecast of 4.2 million doses. By April, field data suggested demand closer to 3 million in the first year, and the plant had scheduled capacity it would not need. The paper reconstructs how the decision was made, compares what members knew with what the group discussed and explains the gaps with research on group decision making.

Reconstructing the Decision

The decision was reconstructed from meeting notes, slides, the project log and interviews with all nine members. In October, the marketing lead presented a forecast of 4.2 million doses based on the size of the target cattle market and an assumed share. The team discussed it in two meetings. Several members raised questions, but the forecast was adopted in November without change, and supply chain built a production plan on it. No alternative forecast was presented, and the team did not set a decision rule; agreement was declared when no one objected at the end of the second meeting.

What Members Knew

Interviews revealed that several members held information relevant to the forecast that never entered discussion. The sales lead knew from customer conversations that large feedlots were locked into multi-year contracts with a competitor's vaccine. The regulatory lead knew that the label would initially exclude calves under a certain weight, a sizable segment. The plant quality manager knew that the first production lots would require extra release testing, delaying availability by several weeks. Each piece of information pointed toward a lower first-year volume; together they explained much of the eventual shortfall.

Hidden Profiles

Stasser and Titus (1985) showed experimentally that discussion gravitates to facts everyone already knows while facts known to a single person tend to go unmentioned, even when the unshared information is decisive. When the best choice can be seen only by pooling unshared information, a situation they called a hidden profile, groups frequently choose the option favored by the shared information. The launch team's decision fits this pattern. The market size data were shared by all; the contract, label and testing information were each held by one person. Discussion centered on the shared data, and the forecast reflected it.

Anchoring and Hierarchy

Two further factors narrowed discussion. The marketing forecast was presented first and in polished form, which set an anchor that later comments adjusted only slightly. And the marketing lead is a director, senior to most other members, including the sales lead, who said she was reluctant to contradict a director in front of the group. The previous paper found moderate psychological safety, lowest among newer and plant-based members, which helps explain why the plant quality manager did not raise the testing delay. Status and safety thus filtered which information surfaced.

Agreement by Fatigue

The team had no explicit rule for reaching a decision. Kerr and Tindale (2004) reviewed research showing that groups' implicit decision schemes, such as majority rule or truth wins, strongly shape outcomes, and that groups often converge on positions favored by the initial distribution of preferences. In the launch team, the implicit scheme was that a proposal stands unless someone objects, which favors the first proposal and places the burden on dissenters. Several members said they had doubts but assumed others had checked the numbers, and the second meeting ran late, so silence became consent.

Was It Groupthink?

Janis (1982) coined groupthink for the way tightly knit groups let their wish to agree crowd out a hard look at options, marked by symptoms such as self-censorship, an illusion of unanimity and pressure on dissenters. Some symptoms appeared: self-censorship by the sales lead and an assumed unanimity. But the team was not especially cohesive in November, and there was no direct pressure on dissenters. The evidence fits a failure of information pooling and decision procedure better than full groupthink, which matters because the remedies differ.

Consequences

The inflated forecast had real costs. The plant scheduled capacity for 4.2 million doses, raw materials were ordered accordingly and two seasonal production staff were hired. Revised plans in April reduced the first-year production target to 3.1 million doses, leaving excess materials with limited shelf life. Marketing budgets based on the higher forecast now need to be cut. The cost of revising the decision exceeded what a more thorough discussion in October would have required.

Redesigning the Decision Procedure

Research suggests several remedies, which the team has adopted for remaining decisions. Before major decisions, each member will submit relevant information in writing, so unshared knowledge reaches everyone before discussion begins. Proposals will be circulated with at least two alternatives, reducing the pull of a single anchor. A member will be assigned to argue the strongest case against the leading option. The team will state its decision rule in advance, consensus for decisions affecting more than one function, with a recorded check of each member's position. And I will ask junior and plant-based members to speak first in discussions of their areas.

The Leader's Part

My own role deserves examination. I allowed the marketing forecast to be presented as a finished product rather than a draft, did not ask members for independent estimates and declared agreement when time ran out. A leader who wants unshared information to surface must create the conditions for it, by asking directly, holding back a personal view until others have spoken and treating dissent as useful. Recognizing these lapses is part of applying the research to practice, not only to the team.

Testing the New Procedure

The new procedure was used in April for the decision on launch pricing. Written inputs revealed that the finance lead had distributor margin data that changed the analysis, and the assigned critic raised a regulatory concern about promotional claims tied to price. The decision took longer, three meetings rather than two, but members rated their confidence in it higher, and no new information has since emerged to challenge it. One trial does not prove the procedure works, but the early result is encouraging.

Limitations

Reconstructing a decision months later relies on memory, and members may emphasize information they now know was important. As the team leader who allowed the process, I may underweight my own role. And other factors, such as market changes after November, contributed to the shortfall. The analysis is therefore best read as an explanation of why the team failed to use information it had, not as a full account of why demand was lower.

Conclusion

The launch team accepted a first-year forecast of 4.2 million doses while three members held information pointing lower. A hidden profile, an early anchor, status differences, moderate psychological safety and an implicit rule that silence means agreement explain why that information never surfaced. The pattern reflects a failure of information pooling more than groupthink. Written pre-inputs, alternatives, an assigned critic, an explicit decision rule and inviting junior members first have been adopted, and an early test is encouraging. The next module will examine conflict and negotiation within the team.
