Process Decisions

Description

A Process may contain a number of related decisions and actions. This can result in a number of types of models that represent the problems and the outcomes of the decision process.

Additional information can be found in ISO 15288:2023:

  • 6.3.3 Decision Management Process

  • 6.3.4 Risk Management Process

  • 6.4.6 System Analysis Process (for single parameter based decisions)

Contents

There are many types of decision models / tools that help describe processes. These are:

  • Decision Trees

  • Outcome Analysis (related to reviews or stages)

  • Decisions modelled in Activity Diagrams related to a process.

  • Log of decisions and rationalle

  • Others....

Note: These activity models also need to provide a way to identify a "System Interaction Point".

Languages, Notations, Conventions

Some tools have decision tree models others can be embedded in Activity Diagrams

Methods - Create, Analysis, Identify

See the procedures for each type of models / diagram being produced.

Modelling Techniques

methods and techniques

These decision analysis approaches need to be in line with Decision Analysis found in ISO 15288.
