The owner-input-output model
A durable workflow needs a single accountable owner, clear inputs, and a visible output before it can be managed.
The model
The owner-input-output model is a simple way to test whether work is manageable. The owner is accountable for movement. Inputs are the facts, approvals, materials, or requests needed to begin. The output is the record, decision, delivery, or state change that proves the work is complete.
Why owner matters
Shared responsibility is useful for contribution but weak for accountability. When no single owner exists, follow-up becomes social negotiation. A workflow should allow many contributors, but one owner must be able to say whether the work is blocked, complete, rejected, or waiting for a decision.
Why inputs matter
Unclear inputs create rework. A request may look simple while missing scope, deadline, authority, cost limit, security expectation, or acceptance criteria. Defining inputs is not delay; it prevents people from solving the wrong problem quickly.
Why output matters
Work without a defined output can continue forever. A useful output is observable: a decision recorded, access removed, restore tested, message sent, review completed, or issue closed with evidence. The output lets the team stop safely.
How to apply it
Before formalizing any recurring activity, write one sentence for each part: owner, input, output. If any sentence requires debate, resolve that first. The workflow will be stronger and shorter afterward.
