A practice manager approves a supplier change after weeks of complaints about delays. The new terms are better. The team starts the handover that afternoon.
The next morning, a director reverses the decision without speaking to the manager first. He tells staff to stay with the old supplier until he has “looked at the risk properly”.
By lunch, both instructions are in circulation. Accounts process one set of invoices. Operations follow another. The supplier receives mixed messages about stock, timing, and approvals. Staff stop asking what the right answer is and start choosing the answer that covers their backside. Work slows. Errors appear.
By the end of the week, the problem is no longer the supplier but that nobody can say who actually owns the call.
Split Authority
This is an operating-level authority failure. Two people act as final decision-maker on the same issue. Both believe they are entitled to do it. Staff receive conflicting instructions, and the system breaks under ordinary pressure.
The problem is that the firm has allowed approval rights to be granted by habit, seniority, and access rather than in writing. People rely on past practice until past practice produces two versions of control.
Two owners on one decision means no owner at all.
Analysis
The sequence is predictable.
First, responsibility expands without being documented. A manager begins approving routine changes as the business grows. A director still treats the same area as a reserved authority. No one records the boundary.
Second, pressure exposes the overlap. A live issue lands. One person acts for speed. Another intervenes for control. Both think they are correcting risk.
Third, staff split their behaviour. Some follow title. Some follow proximity. Some follow whoever spoke last. Workarounds appear because the guidelines are unclear.
Fourth, trust drops. Meetings increase. People start copying extra recipients into routine emails. Approval becomes slower because everyone is trying to avoid being the person blamed later.
That is how an operational decision turns into a control dispute. The trigger looks small. The structure underneath is not.
Why It Matters
Split authority creates cost. Work is repeated. Suppliers lose confidence. Staff protect themselves rather than move quickly. Directors start treating normal decisions as tests of control. Once that starts, the dispute becomes about status, risk, and who gets to reverse whom.
