Level 0 is what I call evaluation before any training has been done. It is a snapshot of current-state performance. You may already have done this in your front-end needs assessment, but if you didn't, and you plan on evaluating after the new initiative, then it is imperative that you establish current-state benchmarks before deploying the new solution. This may sound obvious, but astonishingly few corporations do this. In the rush to deploy new and better solutions based on technology, people overlook this first crucial step. Establish current-state baselines before you proceed. You will be richly rewarded.
