Being an interim manager — in baseball and other industries — is a tough job. You’re pretty much guaranteed to inherit a bad team in turmoil. Firing the old manager itself causes disruption. If you’re the interim person’s boss, you just want the operation back running smoothly.

The ideal interim person should have familiarity with the organization and experience with similar situations. Interim designations fit the bill when the organization needs immediate senior administrative capability, but isn’t ready or able to fill a permanent position.
