How a disjointed senior team was rebuilt into a high-performing leadership group

The Client

A US-owned global packaging company with more than 14,000 employees and over 50 manufacturing sites worldwide. The UK site in question was a significant operation with a strong operational history, facing a critical moment following leadership turnover. A new plant manager, an inherited senior team, and a US parent company measuring monthly against benchmarks the site was not meeting.

The Challenge

Leadership misalignment does not stay in the boardroom. In a manufacturing environment, it cascades with speed and visibility. The senior team's inability to function as a unit showed up in how decisions were made and communicated, in the quality of the relationship between management and the shop floor, and ultimately in the operational metrics that determined the site's standing within the global network.

The new plant manager had inherited a group that had formed without him, with its own existing dynamics, informal hierarchies, and unresolved tensions from the previous regime. The pressure from the US parent company for quick results created a temptation to focus on process and output rather than the relational and cultural root causes of the underperformance. That temptation is almost always wrong to follow.

What the site needed was not a new process. It needed a leadership group that could function as one, that could make decisions collectively and stand behind them, that could communicate with the shop floor in a way that built rather than eroded trust. That was the gap, and it was a psychological gap before it was an operational one.

What We Did

Wharton Global's starting point was a structured diagnostic that established the facts before any intervention was designed. The UK site was benchmarked against higher-performing plants within the same global network, which produced a clear and specific picture of the gap: not in technical capability or operational infrastructure, but in the quality of senior team collaboration and the coherence of leadership communication.

Individual and team behavioural assessments surfaced what the benchmarking hinted at. Two specific patterns emerged consistently. The first was a deficit in what the Leadership Excellence Model identifies as personal drive, the sense of individual investment in the outcome that distinguishes a leader who shows up fully from one who is professionally present but psychologically elsewhere. The second was a significant deficit in psychological safety, as defined within Hayes' Exceptional Teams Framework: the degree to which team members felt able to raise problems, challenge decisions, and admit uncertainty without personal cost. In a team where psychological safety is low, problems are hidden until they become crises. In manufacturing, that dynamic is both common and expensive.

The intervention was phased across twelve months and operated on two levels simultaneously. At the team level, structured development workshops rebuilt shared purpose, clarified roles and accountabilities, and created space for the specific disagreements that the diagnostic had surfaced to be worked through rather than managed around. These were not team-building sessions. They were structured work on existing tensions, facilitated by people with the psychological expertise to keep the conversation productive rather than defensive.

At the individual level, one-to-one coaching worked with specific members of the senior team on the personal development their profile indicated they needed. Some needed to develop their capacity to challenge upward. Some needed to develop their ability to create safety for others. Some needed support with the transition from functional expert to enterprise leader. The coaching was matched to the individual, not delivered as a standard programme.

The Re-form rhythm was embedded as a structural element of the team's ongoing life: an annual workshop that returned the group to first principles, reassessed its composition and shared purpose, and recommitted to the cultural standards the team had set for itself. This is an evolution of the classic Tuckman model, designed to prevent the regression that is almost inevitable when a team stops actively maintaining its culture and assumes it will sustain itself.

The Results

When all three metrics move together, it is not an efficiency gain. It is a cultural shift showing up in numbers. Productivity without on-time delivery improvement suggests a different problem was being solved. All three moving together, in a sustained way, is what leadership alignment looks like in operational terms.

The relationship between the senior team and the shop floor improved in ways that were visible and reported by the workforce. Clearer communication, more consistent presence, and the credibility that comes from a management group that is clearly aligned with each other rather than visibly divided. In manufacturing, the shop floor reads the senior team with considerable accuracy. When the team is coherent, the workforce knows.

The annual workshop programme has continued since the initial engagement. That sustainability is itself an outcome. A business that treats culture as an annual practice, not a one-time fix, is a business that understands how culture works.
