G'day Michael. Thanks for identifying the software - Paula was interested in that sort of information.<br><br>re. arrows: usually the primary actor (the one wanting response from the system and initiates the transaction) has an arrow pointing to the secondary actor (the one who provides a service to the system).<br>
<br>The direction of the arrows is sometimes obvious (when the case study is known), sometimes it's not. A good skill is being able to reverse-engineer a case study from a UCD.<br><br>I've not met additional system boundaries before, so you could be quite right. Does anyone else have 2c to spend?<br>
