The Approval Fits in Your Pocket
Some operational work takes a whole screen to prepare and only a moment to approve. Someone gathers records, reconciles a spreadsheet, and checks the numbers before asking another person for a decision.
Automation can separate the preparation from the approval. That opens up a useful design question: how much of the decision can fit on a phone?
Make the decision small enough to understand
Consider an invoice matched to a purchase order with a 2% price variance. An approval screen could show the invoice, the purchase order, the amount of the difference, and the action that approving it would take. The source records should be close enough to inspect without hunting through another app.
That can be a reasonable phone-sized task. An unfamiliar exception or a decision with broad consequences may need more room and more time. The interface should make it easy to move into a fuller review.
What has to be true first
The summary must match the underlying records. A person approving a description of the work needs to be able to check it, with the source one tap away.
The approval must authorize exactly what was described. Permissions and validation should limit what the agent can do with that decision.
The default must be safe. If nobody answers, the system waits or routes the request to someone else. Silence is never consent.
I’d design the queue around those requirements before making it available on a phone. A compact screen is useful when it gives someone enough context to decide, inspect the source, or defer the question until they can give it proper attention.
