Inputs

Knowledge of workshop participants

AMOD-022 Enterprise & environment definition

AMOD-015 Example CONOPS from other railway

AMOD-018 Organisation future process framework

OutputsAMOD-023 Operational entity/actor states
Methodology

This activity does not need to be done for every operational entity and actor.

It is only needed when

  • there is a clear and relevant difference in the behaviour of an entity/actor, depending on its state, or
  • the behaviour of the wider system of interest is defined in terms of changing the state of an entity/actor.

In either case it should be fairly clear what the states are, based on knowledge of the modeller; if necessary, a brainstorming workshop can be held to identify candidates and come to an agreement.

The results should be modelled as a states diagram in accordance with modelling rules.

Where there are existing state definitions, but only a subset of them are of interest, then it is permissible to merge some states into a larger one. There is no real need to precisely follow an external definition if it is not helpful to do so.

Tools and non-human resourcesStandards and definitions belonging to particular entities
CardinalityOnce per operational entity, but only where necessary.
Completion criteria

There exists a model view (AMOD-023 Operational entity/actor states) for the entity/actor of interest, that is compliant with its definition and rules.
