Gone are the days of hand-written overhead transparencies and typewriters. If you are involved in the creation of today's learning and performance solutions, you are using software. Also, chances are that the outputs of the efforts to create those solutions are pieces of software, such as computer-based training modules in a SCORM format for an LMS, bite-sized how-to YouTube podcasts, or printed materials created with word-processing, graphics, and presentation software. As elsewhere in the world, software is ubiquitous in the domain of workplace learning and performance. Every workplace learning and performance professional is familiar with ADDIE (analysis, design, development, implementation, and evaluation). It has been the instructional systems design approach of choice for many years and is part of the ASTD competency model, crossing over into multiple areas of expertise, including designing learning, delivering training, human performance improvement (HPI), and measuring and evaluating.
