Introduction

Team development models promise to tell leaders what to expect as a group forms and matures, but they rest on different assumptions about how change happens. This paper applies two well-known models to a team I lead: the launch team for a new cattle respiratory vaccine at Prairie Animal Health, a composite company whose details combine several firms and have been altered. The nine-member team draws from research, regulatory affairs, manufacturing, quality, supply chain, marketing, sales, finance and medical services, and it works partly at the Lenexa, Kansas, headquarters and partly at a plant in Iowa. The paper compares the models, tests them against the team's first eight months and draws implications for my leadership.

The Team and Its Task

The team was formed in July with a deadline: launch the vaccine in time for the following fall's cattle shipping season, about fourteen months away. Members keep their regular jobs and spend roughly a fifth of their time on the launch. Their task is interdependent; regulatory filings depend on manufacturing data, marketing claims depend on regulatory approval and sales forecasts drive production plans. Members did not choose one another, and several had never worked together. I was appointed team leader by the vice president of commercial operations, with responsibility for the launch but no formal authority over members' home departments.

Tuckman's Stages

Surveying earlier research on therapy, training and laboratory groups, Tuckman (1965) concluded that groups pass through a predictable series: forming, in which members orient themselves and test boundaries; storming, marked by conflict over roles and influence; norming, in which cohesion and shared expectations develop; and performing, in which the group channels its energy into the task. Tuckman and Jensen (1977) later added adjourning, when the group completes its work and disbands. Its appeal lies in its simplicity and in reassuring leaders that friction is an expected phase, not evidence that the team is broken. It implies that leaders should expect and work through each stage in order.

Gersick's Punctuated Equilibrium

Gersick (1988) studied project groups with deadlines and found a different pattern. Rather than moving through gradual stages, each group settled on its working assumptions and habits almost immediately, often in the very first session, and held to them through an opening stretch of little change. At almost exactly the midpoint between start and deadline, groups underwent a transition: they dropped old patterns, engaged outside supervisors and adopted new approaches, which carried them through a second phase of inertia to completion. Gersick's model emphasizes the timing of change and the role of the deadline, rather than a fixed sequence of interpersonal stages.

Evidence From the Team's History

Evidence came from my meeting notes, the team's shared project log and half-hour interviews with each member in February. In the first meeting, members agreed to work mainly through their departments, meet every two weeks to report progress and leave cross-functional problems to me to resolve. For the next several months, meetings consisted of status updates. Disagreements between regulatory and marketing about label claims were noted but not resolved; members described the meetings as polite and slow. In early January, near the midpoint of the fourteen-month timeline, the pattern changed sharply.

The Midpoint Shift

In January, the regulatory lead presented a schedule showing that, at the current pace, the dossier would miss the filing window needed for fall launch. The team asked the vice president to attend a meeting, something it had not done before. Afterward, members replaced biweekly status meetings with weekly working sessions, created three cross-functional subgroups and resolved the label claims dispute within two weeks. Interviews describe the shift as sudden: one member said it felt like the team started over in January. The pattern matches the midpoint transition Gersick (1988) observed, set off when a group suddenly confronts how little time remains.

Where Tuckman Fits and Where It Does Not

Tuckman's stages capture parts of the experience. The early months showed forming behaviors, such as cautious politeness and reliance on the leader. But storming, in Tuckman's sense of open conflict over roles, never appeared as a distinct stage; the disagreement over label claims stayed submerged until the midpoint, when it was resolved quickly rather than through a prolonged storm. Norming and performing behaviors emerged together after the transition rather than in sequence. The team's history fits a sequence of inertia, transition and renewed inertia better than a ladder of stages.

Why the Fit Matters

The model a leader believes shapes what the leader does. Under Tuckman's model, I might have waited for storming to arrive and then managed it, or interpreted the polite early months as healthy progress toward norming. Under Gersick's model, the early framework sets the team's trajectory, and the midpoint is the moment when the team is most open to change. In hindsight, the first meeting's decision to work through departments locked in a slow pattern, and I missed an opportunity to shape a better framework at the start.

Hybrid and Remote Factors

The team's partial separation between Lenexa and the Iowa plant also shaped its development. Members at the plant joined meetings by video and reported feeling less included in informal discussions at headquarters. The weekly working sessions adopted after the midpoint were deliberately held in person once a month, alternating locations, which interview responses suggest helped. Neither model addresses distance directly, which is a limit of applying classic group research to today's hybrid teams.

Implications for My Leadership

Three implications follow. First, the team is now in its second phase, and Gersick's model suggests its new framework will persist to the deadline, so the next few weeks are the time to reinforce good practices, such as subgroup ownership and weekly sessions, before they harden. Second, I should prepare for adjourning, which Tuckman and Jensen (1977) identified, by planning how the team will hand off to commercial operations after launch. Third, for future teams, I will invest heavily in the first meeting and set an explicit midpoint review, rather than leaving the transition to chance.

Limitations

The analysis rests on one team, my own notes and interviews conducted after the midpoint shift, which may have colored members' memories. As team leader, I am not a neutral observer. The midpoint timing could also be coincidental with the regulatory schedule review. These limits suggest treating the conclusion as a well-supported interpretation rather than proof, and testing it on the next team I lead.

Conclusion

Applied to the vaccine launch team, Gersick's punctuated equilibrium model explains the team's history better than Tuckman's sequence of stages: an early framework produced months of polite inertia, and a deadline-driven transition at the midpoint transformed how the team worked. Tuckman's model still offers useful language, particularly for the closing stage. For my leadership, the lesson is to shape the opening framework deliberately, use the midpoint intentionally and plan for adjourning. The next module will assess the team's effectiveness and composition.
