In the Facebook discussion of my recent blog post If an Injection is a solution you knew BEFORE you built the Cloud, why did you need the Cloud? I wrote a phrase that clearly stated that there is a difference between an Obstacle and an UDE. The phrase read “… are obstacles for the implementation, rather than system UDEs.” Thereafter, I was asked what is the difference between an Obstacle and an UDE.
I think that the confusion between the two may be caused by the fact that from the point of view of the global meaning, an UDE is, of course, an obstacle to achieving the desired performance level of the system.
However, when we speak about the difference between an Obstacle and an UDE as TOC Thinking Processes elements, there are four aspects to it.
