According to ISPI (International Society for Performance Improvement) - Human Performance Technology (HPT), a systematic approach to improving productivity and competence, uses a set of methods and procedures -- and a strategy for solving problems -- for realizing opportunities related to the performance of people. More specific, it is a process of selection, analysis, design, development, implementation, and evaluation of programs to most cost-effectively influence human behavior and accomplishment. It is a systematic combination of three fundamental processes: performance analysis, cause analysis, and intervention selection, and can be applied to individuals, small groups, and large organizations.
Businesses do not place enough importance on the Human Performance process.

They tend to skip step number three and miss out on the opportunity to uncover the true root cause.
