<div dir="ltr"><div>Hi Mary</div><div><br></div><div>The whole UCD is odd. I'm wondering why a UCD is written for the <b>current</b> system. If it's going into an SRS, should the UCD not describe the functionality of the proposed <b>new</b> system?</div><div><br></div><div>Use cases are usually shown as programmable functional requirements of the new proposed system (in a verb/noun format), such as 'Convert Measurements', 'Solve Equations'. </div><div>This UCD implies that the finished system can 'find component specifications' and 'ask mentor for equations', etc. This is obviously not what the solution should be able to <b>do</b>. </div><div><br></div><div>As for actors, who will be using the system? To whom will the system send data, or request data? They should be shown as actors. </div><div>I suppose a UCD <b>could</b> have only one actor, but it's not common.<br></div><div><br></div><div>Oh - and the <<extends>> should all be <<includes>> since they are not conditional. <br>If they <b>are</b> conditional, the condition should be attached. And if they <b>are</b> <<extends>>, the arrows' directions need to be reversed.</div><div><br></div><div>Mark</div><div class="gmail_extra"><br><div class="gmail_quote">On 25 April 2016 at 17:32, Mary Ho <span dir="ltr"><<a href="mailto:homn@aquinas.vic.edu.au" target="_blank">homn@aquinas.vic.edu.au</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">I have a student who is really good and he has created a use case with only 1 actor, I'm not 100% sure if this could be correct.
