Thanks for your response Nancy..

Having been involved in Software Engineering and CASE since 1980, I know in my heart you are right. Unfortunately, I have a steep learning curve to go through because my staff is so wedded to our existing code, mostly in their head with very little documentation, that I need a transition plan that is eluding me that will keep me going while we make the transition. If you know of any approach / courseware that would help I would like to hear about it.
