An application activity model (AAM) is provided in AP239 as an aid to understanding the scope and information requirements defined in AP239. The model is presented as a set of figures that contain the activity diagrams and a set of definitions of the activities and their data.
This DEX will support a subset of the activities and data flows. These are highlighted in yellow in the subsequent figures.
Activities and data flows that are out of scope of AP239 are marked with an asterisk.

The following terms are used in the application activity model.
action to determine the potential faults or other degraded states that the support solution shall address, including cause, effect and other relationships between them, as applicable to each product function requiring support, part, and attachment slot
NOTE The ARM of this part of ISO 10303 defines the concept of predicted states of a product and this concept is appropriate for representation of faults. A product can be either a part of a function. The sequences of individual faults involved in a failure can be represented by the relationship between predicted states.
set of assured and related information used to develop and deliver support for a product in focus, including feedback from using and supporting the product over its life cycle
NOTE Related information includes records of the history of the usage or support of realized products, design and support analysis results and reasons why decisions were taken. Such information includes design and failure analysis records, logistic support analyses, running hours, environment descriptions, operating profiles; test results, records of maintenance activities, resources used, and faults found plus any other content deemed relevant to life cycle support.
