Map one common order from acceptance to completion. Ask each team member what work it creates and where it waits. Include the administrative handoff, especially when information must move between the counter and a service team.
Use that picture when deciding how many orders or appointments to accept. The aim is not a perfect forecast, but a clearer view of the commitments already made. Review actual completion times and update the assumptions. A business that understands its full workload can give customers more realistic expectations and spot the task that needs improvement before taking on another promotion or extending availability.
