Agree. The PSM discussion in the study design refers to use cases in both the analysis and design phases. I reckon it shouldn't be in the latter.<br><br><div class="gmail_quote">On 23 November 2010 16:28, Kevork Krozian <span dir="ltr"><<a href="mailto:K.Krozian@fhc.vic.edu.au">K.Krozian@fhc.vic.edu.au</a>></span> wrote:<br>

<p class="MsoNormal" style="margin-bottom: 12pt;">Hi all. The study
design's PSM discussion lists Use Cases as being a useful tool to use during <b>physical
design</b>.<br>
<br>
I would have thought they would be a <b>logical</b> design tool since they are
so abstract and emphasise functionality requirements rather than implementation
methods.<br clear="all">
