'''Fit:''' refers to the ability for the part or feature to connect to, mate with, or join to another feature or part within an assembly. If a part requires “fit” it usually implies that there are relatively tight assembly [[Engineering_toleranceEngineering tolerance|tolerances]] that must be met in order for the part to be useful.

'''Form:''' refers to such characteristics as external dimensions, weight, size, and visual appearance of a part or assembly. This is the element of F3 that is most affected by an engineers choice of enclosure, chassis, control panel, etc. that becomes the outward "face" of the product.

'''Function:''' is a criteria that is met when the part performs its stated purpose effectively and reliably. In an electronics application, Function can depend on the [[Solid-state_electronicsstate electronics|solid-state components]] used, the [[software]]/[[firmware]], and quite often on the features of the electronics enclosure selected. Poorly placed or dimensioned ports and misleading/missing labeling are just two of the most common ways in which an enclosure can fail the Function criteria of F3.
