Type vs category

A type is the single thing an item fundamentally is; categories are the many attributes you want to filter it by. One item has one type and any number of categories.

Also called: category vs type, equipment types and categories.

One type, many categories

The distinction is structural, not a matter of taste. A type answers "what is this?" — a camera, a vehicle, a laptop — and there is exactly one right answer. Categories answer "what is this like?" — battery-powered, requires certification, owned by Site B, PAT-tested, insured separately — and any number can be true at once.

Get this backwards and classification collapses. Teams that use types for attributes end up inventing hybrids like "Camera – Site B – Insured", which multiply until nothing is findable and no two people classify the same item the same way.

A test for which one you need

Ask whether an item could reasonably need two of the values at once. If yes, it is a category. A drill cannot be both a drill and a vehicle, so that is a type. A drill can be both cordless and requiring PPE, so those are categories.

Second test: would you ever want to filter by this in combination with something else? Combination filtering is what categories exist for.

Keep the type list short

Types are most useful when there are few enough to hold in your head — typically ten to thirty for an equipment register. A list of two hundred types means attributes have leaked into it, and the fix is to move them out into categories rather than to keep subdividing.

Categories can be as numerous as you like, because you never have to browse them all at once; you filter.

What goes wrong without it

Mixing attributes into the type list produces hybrid types that multiply combinatorially, so equipment becomes unfindable and two people classify the same item differently.

How Itefy handles it

Itefy separates the two deliberately: one type per item, plus as many custom categories as you need, and the item list filters on any combination of them. Read more.

Type vs category — common questions

Can an item have more than one type?

No — that is the point of the distinction. If an item genuinely needs two classifications at once, at least one of them is a category rather than a type.

How many equipment types should we have?

Few enough to remember, usually ten to thirty. If the list is running into the hundreds, attributes have crept in and belong in categories instead.
