Mobile approval is useful when a manager can make a sound decision without returning to a desk. It becomes risky when the phone screen shows only a total and a large Approve button. The interface should make the proposal, its consequences and its supporting evidence clear enough for the decision being made. Convenience should remove delay, not remove understanding.
Show what changes after approval
A building-services manager approving an extra part needs the job, reason, amount and effect on the customer arrangement. A vague description such as Additional work leaves too much to infer. Put the material facts together and make supporting photographs or notes available without losing the decision context. Distinguish acknowledgement from authorisation. If a worker only needs to confirm they have read a notice, do not use the same language and visual treatment as an action that commits the business to expenditure or changes a customer's service.
Handle stale and competing decisions
A proposal may be revised after the manager opens it, or another authorised person may act first. Before accepting a decision, confirm that it applies to the version the person reviewed. Explain any change and let them inspect the revised details. A notification can link directly to the request, using platform linking capabilities such as Android App Links, but opening the link should not itself approve anything. Ensure the signed-in person has the relevant authority and that a forwarded link does not expose restricted supporting material.
Keep the decision record useful
After submission, show who decided, what was decided and whether any follow-up remains. Allow a reason for rejection or a request for clarification so the requester knows how to proceed. Avoid forcing a complex decision into a tiny comment field with no ability to inspect attachments. Test accidental double taps, interrupted connections and a session that expires while evidence is being reviewed. An approver should be able to return and discover whether the decision was received without guessing or submitting it again. Review the workflow with both requesters and approvers during the pilot.
- What information would an approver normally ask for before agreeing in person?
- Does the decision apply to a clearly identified version of the request?
- Can a reviewer request clarification without pretending to approve or reject?
- How is a received decision distinguished from a tap still waiting to send?
