ABSTRACT
If performance is what we are striving for, lasting performance must be the Holy Grail. How true is this statement? Well, there is certainly some truth to it. We want to secure lasting performance in order to achieve our project objectives. Lasting performance by itself, however, is not sufficient if it does not account for change. We live in a dynamic, ever-changing world. This is a truism. Also, we know that we can expect lots of changes in long-lasting projects. This, too, is common sense. The same applies to the statements that we make mistakes and that knowing everything is an illusion. But, if we know all this already, why is it then that reflection, learning, and plan adjustments are not common practice in so many projects? Maybe it is not common sense after all that learning is important in life and thus in projects.
