To clarify, the data is the process definitions, or the rules that govern what happens under which circumstances. The code is spread between the workflow engine and process state tracking. That's definitely a helpful way of looking at it, although writing an engine to parse a custom rule-set is (I believe anyway) a very serious undertaking. But maybe that's why you're suggesting a compromise between a full workflow engine and hardcoding behavior? That feels right to me, especially since I strongly advocate the "build one to throw away" school of thought, and this is a first brush at something that will likely be reworked at some point.
I liked this quote from that IBM document: "Effective workflow processes have three basic components: data, process logic, and a directory of participants." (pg. 2)
Thanks diotalevi.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
