    OUTPUT CONSTRAINT OUTPUT CONSTRAINT

    definition a constraint which holds immediately after an activity has taken place

    variants An output can be one of several types. We have identified four types: authority, condition, resource and other. Just as for inputs, "other'' is provided to allow for enhanced modelling, for instance the representation of spatial constraints.
    examples see authority, effect and resource

    term in other fields In IDEF, there are is only one output to an activity, in contrast to the three inputs (input, control and mechanism). Experienced IDEF modellers use the arc labels, naming conventions and the "notes'' system in an IDEF support kit to encode the different types of output.
