Designing approval workflows that do not get stuck in LINE

Many organisations already have an approval workflow. It just lives across a form, a LINE chat, an email thread, and somebody’s memory. That feels fast until a request is urgent, the approver is away, or someone needs to explain the decision later.

Treat approval as a state change

The core model is simple: a request has an owner, a current status, a next action, and a record of what changed. “Waiting for approval” is not enough. The system should know whose decision is needed, when it was requested, and what information they need to make it.

Design for the awkward cases first

• What happens when the approver is on leave?
• Can a request be sent back for more information without losing its history?
• Can the approver delegate once, with an expiry date?
• What happens when the budget or policy changes mid-process?
• Who can see sensitive supporting documents?

Keep the decision and its context together

A notification can be useful, but it should lead back to the request, not become the system of record. Show the amount, reason, requester, supporting files, policy checks, and previous decisions in one place. Make the approve, reject, and request-changes actions unambiguous.

Measure the workflow after launch

Track time to first response, time in each approval stage, rejection reasons, and requests that are reopened. These measures tell you whether the software is improving the operation or simply moving the same delay to a new screen.

The best approval workflow makes the right action easier than sending a message to ask what is happening.

Start with one approval path and its real exceptions. Once the team trusts the record, additional rules and integrations can be introduced without making the first release harder to use.
