The Landscape has become a touchstone for us as performance improvement professionals. When we want to check the validity of a concept, a model, a tool, or an approach that is new to us, we come back to the Landscape. We look to the Landscape to show us where the new item fits in the performance world, how it supports the Principles of Performance Technology, at what levels of the work environment it could be effective, and to what extent it would mesh with the existing culture. Everything we do, or that can be done, to improve performance is contained in the Landscape.
