Slide 22 of 32
Notes:
Table 6 lists the actions, the process triggered by each action, the consequence of the action, and the conditions under which the consequence will occur. The actions in this PEAnet are statements of the manager to mark. The manager is not portrayed but does the actions. Note that the actions could occur in any order but in this case the usual order is as listed.
What happens? When the first statement (action) is executed the process Make Mark Happy changes the property mood to the value happy. The happy portrayal of Mark corresponding with the value happy is shown. When the next statement (action) is executed the process Make Mark sad changes the property mood to the value sad and the corresponding portrayal showing a sad mark is displayed. A similar chain of events occurs for the third statement. For the forth statement the process Make Mark angry changes the value of mood to the value angry only when the property boss present has a value of no. When the boss present property has a value of yes then the value of mood remains or is changed to surprised.
This is a significantly oversimplified PEAnet to illustrate the role of properties, property values, conditions, and consequences. Actions can trigger more than one process. Processes can change more than one property. There can be many or few conditions. Conditions for a process may have been set much earlier in a complex process that consists of many events. Hopefully the reader can extrapolate to the more complex case from the information given.
