Interaction analysis

Interaction analysis is a stage of function analysis of devices that identifies interactions between the components included into the component model.

Overview

The primary purpose of the interaction analysis is to identify whether interactions exist between components within the component model. At this stage, the consequences of the identified interactions are not considered; the focus is solely on their presence.

Note that the interaction analysis is a stage of function analysis that is performed only for devices. In function analysis of processes this step is entirely skipped because there are no interactions between components.

Procedure

To facilitate the interaction analysis, the previously developed component model is utilized. The analysis is typically conducted by creating an interaction matrix, which is the output.

The matrix is created according to the following steps:

  1. create the matrix template with the number of columns and rows corresponding to the number of all identified components,
  2. fill out the matrix template with the names of components in column and the raw headings, in the same order,
  3. check if there is any interaction for each pair of components in the matrix; record the results of your analysis – with a “+” sign if the interaction exists, a “–” when it does not,
  4. check if the interaction matrix is symmetrical relative to the diagonal running from the upper left-hand corner to the lower right-hand corner.
