In brief: Two browsers can select the same slot almost simultaneously; A mere display check is therefore not sufficient. Transactional checking, clear reservations and idempotence protect appointments from overlapping.
Why this matters now
Two browsers can select the same slot almost simultaneously; A mere display check is therefore not sufficient.
The useful target state
Transactional checking, clear reservations and idempotence protect appointments from overlapping.
How to proceed in a structured way
Implementation should start small enough to learn from real operations, but complete enough to test handovers and exceptions realistically. The following sequence has proven useful:
- 1Only check the slot when saving
- 2Merge employee and resource occupancy
- 3Limit multiple appointments per customer based on rules
- 4Respond to conflicts with a clear alternative
Practical check before production use
A successful demo is not proof of reliable operations. Test missing permissions, parallel changes, network interruptions and invalid input as well.
- Time intervals do not overlap
- repeated requests do not generate a second appointment
- manual appointments follow the same rules
Conclusion
Transactional checking, clear reservations and idempotence protect appointments from overlapping. The greatest benefit emerges when the business team, responsible owners and technology use the same process definition. A controlled pilot makes value and limitations visible before more teams or locations follow.
Frequently asked questions
Does this require replacing the entire system?
Usually not. A clearly bounded process is the better starting point. Existing core systems remain authoritative and are supplemented only where handovers, approvals or business logic are missing.
How should a useful pilot begin?
With a measurable problem, a manageable user group and agreed success criteria. Value, errors and open dependencies are then reviewed together.
