Plenty of internal processes need someone to say yes before anything happens. Expense requests, content publishing, leave requests, purchase orders. Most teams run these on email and memory, which works until the volume grows or the person who remembered everything goes on holiday.
An approval workflow is that process written down and enforced by software.
What an approval workflow is made of
A request moves through one or more approval steps before it is finalized. Four pieces do the work:
A request submitted by a user. A status field, usually Pending, Approved and Rejected. A list of approvers or managers. Actions that change the status based on their decision.
That structure is what lets a team track decisions and see the state of a process without asking anyone. Everything else is variation on it.
Where it gets used
Expense approvals, purchase requests, leave requests and document review cover most of what teams build first. They share a shape: a form, a queue, a decision, a notification.
The interesting variations start when the routing gets conditional. Requests above a threshold need a second approver. Requests from a particular department go to a particular manager. Anything that sat untouched for three days escalates. None of that is hard to build, but it is worth deciding before you start rather than bolting on later.
What you need before you start
A connected data source, and a clear answer to three questions.
Who can submit? Who approves, and is it one person, a role, or a chain? What happens when nobody responds?
The third question is the one people skip, and it is the one that determines whether the workflow survives contact with reality. A request with no timeout sits in Pending forever, and the requester goes back to sending emails, which is what you were trying to stop.
Building it in Jet Admin
Connect your database first. Jet Admin supports over 100 integrations and reads your tables and fields automatically, so the interface has something to build on.
Then create the submission form. Keep it short. Every field you add is a field someone has to fill in before they can ask for something, and long forms push people back to messaging you directly.
Next, configure what happens on approval and rejection. In Jet Admin these are actions that update the request record based on the approver's decision. This is also where notifications belong: tell the approver when a request arrives, and tell the requester when it resolves.
Then set permissions, so approvers see the queue and requesters see their own requests.
Finally, test with real requests before anyone depends on it. Submit one, approve it, reject another, and try leaving one untouched to see what happens. The last case is the one that will occur most often in the first month.
Two things that go wrong
The workflow gets more approval steps than the decision deserves. Three approvers on a $50 expense is a process designed by someone who has never submitted one. Each step adds delay and diffuses responsibility, and past two steps most of what you are buying is the appearance of control.
The status field stops matching reality. This happens when people can approve things outside the system, by replying to a message or telling someone in person. If a decision can be made off the record, the record becomes decorative. Either the workflow is the only route, or it is documentation of a process that happens somewhere else.
What you get
Instead of tracking requests through inboxes, the whole process sits in one place: who asked, what they asked for, who decided, when, and what the decision was. That history is usually the reason the workflow gets built in the first place, and it is worth more than the time saved on any individual request.
