A new hire at the shop gets handed whatever spare key happens to be in the drawer, and it turns out to open the stockroom, the back office and the safe room all at once. The owner realizes nobody actually decided who should open what.
A master key hierarchy usually has three layers. At the bottom, an individual change key opens one door or a small keyed-alike group for the person who needs it. In the middle, a sub-master opens a defined group, such as every door on a floor or in a department. At the top, a single master opens the whole set and is kept to a short list of people. Master key system design is the process of deciding where those layers sit for a particular business, choosing hardware that can support them, and cutting and testing the keys so each layer works exactly as planned, no more and no less.

Scene 1
Before anything is redesigned, the locksmith reviews the keys already in circulation: how many exist for each door, which ones are stamped or coded in a way that identifies what they open, and which staff members currently hold more access than their role calls for. This review often surfaces the exact problem the new system needs to fix, whether that is a master key copied one time too many or a department that was folded into another without anyone updating who could get in.
Scene 2
Design starts with the smallest unit, the individual change key, and works upward. Each door that stands alone gets its own combination; doors that should share access are grouped under a sub-master; and a single top-level master is reserved for the short list agreed earlier. Building in this order keeps the levels honest, since a sub-master or master is only created where a real group of doors justifies it, rather than being added because it seems useful in the abstract. The result is a hierarchy that matches the organization rather than one imposed on top of it.
Scene 3
The chart, the issuance log and any spare keys are handed to a named administrator, not left as loose paperwork or scattered across whoever happened to be present. If that role changes hands, custody of the record moves with it deliberately, along with a signed acknowledgement of what is being transferred, so the system's history does not quietly disappear along with the person who used to manage it.

Through the chart and issuance log rather than memory. Each level is tied to named roles or people, each key is marked to reflect its level rather than the door it opens, and any change of hands is recorded with a signed receipt. That record names every authorized holder for a door, though it can only account for a key that was never copied, loaned or picked up by someone outside that list.
It depends on how the keyway is controlled. With a restricted system, spare blanks are typically held by the locksmith against the authorized record rather than stored loosely on site, since that is what keeps duplication contained. With a standard keyway, keeping a few spare cylinders of the same platform can simplify a later addition, though it is not required.
Sometimes, but it depends on the keyway and pinning platform each brand uses; some are compatible with one another and some are not. Where a mix already exists on a property, the assessment identifies which cylinders can be brought into a single hierarchy and which need replacing with a matching platform so every level pins correctly across the whole set of doors.
