I found this to be on par with other canned workflow tools. That is, not so great overall.

If you don't already have a team of coders, but have talented and technically-inclined individuals itching for a new challenge, this may be a good way to enable them to produce simple throwaway forms and workflows. Also found BP Logix tech support to be above average, though product development support is not included in the basic software license.
Don't believe the marketing hype. No, your staff won't be cranking out complex forms and processes within days, weeks, or probably even months. You will require a substantial training investment and years of experience for workers to become truly productive with this. It is like learning a programming language, except instead of writing code you are mousing everywhere. And, unlike code, which represents the utmost in flexibility, you are working within the limited confines of one tool that does not support such common development tasks as renaming fields, adding more than x number of records to a drop-down, or diffing files to find out what has changed. When your knowledge workers become frustrated trying to accomplish a task for which the tool was not intended--and this will happen for all but the simplest project requirements--you will be tempted to recruit your coding team to assist. This is a good way to alienate your coders, who probably won't want to invest the time learning a tool that is inherently inferior to what they already have and know.
