The problem and the solution. Criticisms of structured training include its perceived lack of flexibility and creativity. Although disciplined adherence to a linear process may not appear to be problematic in the analysis, design, development, and evaluation phases of instructional design processes, it would be lethal in the implementation phase. Flexibility and creativity are essential when facing learners in real time. Because not every contingency can be identified ahead of time and learners can be fickle, during the implementation phase trainers must clearly understand what is to be achieved and have an adequate repertoire of methods and techniques with which to achieve it. This article surveys developments in the implementation of training focusing on the interaction between instructor and learner. This focus helps reframe the view of implementing training to include the need for increased flexibility and effectiveness through formal and informal learning within organizations.
