A leader who holds the formal right to decide makes the call after hearing the arguments, announces it, and holds people to it, without waiting for an agreement that will not come.
Borderline: whether this move is justified depends on the situation, and only the person in it can judge.
An example
Three plants, three strong cases, and a leadership team split evenly among them: the chief operating officer of a snack food manufacturer had spent five months trying to reach agreement on which plant would close. Each plant manager had allies in sales and finance. The decision was hers under the board's delegation. In a team meeting she said she had heard every argument, that she would decide by the end of the week, and that she expected the team to carry out the decision whatever it was. On Friday she sent a memo: the Ohio plant would close over eighteen months, for reasons she listed, including two arguments she had rejected and why. She met the Ohio plant manager in person before the memo went out and offered him the lead on the transition. Two team members disagreed openly at the next meeting. Both carried it out.
Why it works
When agreement will not come, consensus-seeking can go on indefinitely while the problem costs money. A leader with the formal right to decide can end it, which makes closing easier and further delay costlier for everyone still arguing. Explicit use of authority is one of several approaches to change, suited to speed and to change agents who hold power, and it has real costs in commitment. It depends on the authority being clear, the hearing being real, and the reasons being explained.
The thinking behind it
John P. Kotter Kotter and Schlesinger's Choosing Strategies for Change (1979) lists six ways to deal with resistance, from education and participation to explicit and implicit coercion. Each suits different situations and carries costs; coercion, in their account, is fast and suited to change agents with power, at the price of resentment. Deciding a plant closure over the team's disagreement is that approach used within formal authority, with its cost in commitment.
Leonard A. Schlesinger Choosing Strategies for Change (1979) treats handling resistance as a choice among methods with different speeds and costs, each legitimate in the right situation. A leader who first hears every argument, involving the people affected, and then decides is combining two of those methods: participation before the decision, and authority to close it.
Kathleen M. Eisenhardt Making Fast Strategic Decisions in High-Velocity Environments (1989) describes consensus with qualification, observed in a study of eight firms: teams tried to agree, and when they did not, the senior executive decided, guided by the team's input. Announcing that rule and then using it is what kept a five-month stalemate from running longer.
When it fits
Decisions within your formal authority that have stalled after a real hearing are the case: closures, priorities, structure, vendor choices. You need the authority on record, a decision that cannot wait, and enough standing to absorb disagreement. It suits situations where speed matters more than full support.
How to use it well
Confirm the decision is yours: the delegation, the budget, the scope.
- Hear the arguments fully, and let people see that you heard them.
- Announce when you will decide, and that you will decide without consensus if necessary.
- Decide, and explain the reasons in writing, including the arguments you rejected and why.
- Tell the people most affected in person, before the memo.
- Hold everyone to carrying it out, and give the dissenters a role.
Then move to implementation. Reopening the decision usually costs more than a flawed decision does.
What it costs and where it backfires
Deciding over disagreement costs commitment: people carry out a decision they did not agree with less energetically, and some will wait for it to fail. Used often, it teaches people that arguing is pointless, and they stop bringing you bad news. Authority stops being legitimate where it turns into threats beyond your role, punishment of the people who argued, or a decision outside your delegation.
When it is used on you
State your disagreement once, clearly, in the right forum, when a leader decides against you within their authority, and then carry the decision out well. If the decision exceeds their authority, raise that with whoever delegated it, with specifics. A record of carrying out decisions you opposed buys credibility for the next argument.
