Brand kits
Not whether the document is thorough. A kit is the identity turned into something your own team can use under time pressure, without asking anyone and without opening forty pages first.
Why manuals fail
They are opened once, admired, saved somewhere sensible and never consulted again. Not because nobody cares, but because when the logo is actually needed it is four in the afternoon, a printer is waiting, and reading forty pages is not one of the available options.
So somebody takes whichever file is on the desktop. It is the wrong format, or last year’s version, or the one with a white box behind it. Nobody was careless — the system simply asked for more time than the situation had, and it will ask for it again next month.
A kit is built the other way round: for the person in a hurry. Files named so the right one is obvious, templates that already contain the decisions, and a document short enough that the part you need is found in under a minute. The decisions themselves live in the identity; the kit is what makes them survive contact with a normal working week.
What your team actually does
Every one of these will happen in your company this year. The kit is judged by how much faster each of them gets.
If the kit does not make those six faster, the kit is decoration. That is the only measure we apply to it, and it is the reason ours are shorter than most.
What you receive

The naming is the part that decides whether any of this works. A folder of correctly produced files that nobody can navigate is the same as no folder at all — which is why we name them for the moment they are needed rather than for how they were made.
Send them over. Often the identity underneath is perfectly good and only the kit is missing — which is a much smaller job than it sounds, and a much cheaper one than starting the whole thing again.
