HPT MODELS

There are so many HPT Models out there. Because there are so many different organizations with various needs and HPT experts with different backgrounds, there are several models that are customized for various needs. For example, there's a process model that shows analyst how to examine a problem; there are diagnostic models to let performance analyst know what HPT can be applied, there are also holistic models that are non-linear and have overlapping domains. The example above is performance model by Atkinson and Chalmers, 1999 (as cited in Wilmoth, Prigmore, & Bray, 2010, p. 17).
