•Mager - performance objectives leading to desired (measurable) outcome behaviors

Danny Langdon designed the diagnostic model known as "Langdon's Language of Work Model".  As is the case with diagnostic models, this model tells the performance analyst WHERE human performance technology may be applied.

"Langdon's Language of Work Model" is designed to be accessible to novices who have an understanding of the knowledge and skills of their performers, yet are unable to express this knowledge systematically.  The model describes performance as flowing from input, moving thru processes and output to consequences.  It employes a feedback loop that reminds the analyst that outside factors, called conditions, affect the input and the process.  The simplicity of Langdon's model allows it to be used to examine performance at four levels: the business unit, the core process, the work group and the individual.  The emphasis on this model and all diagnostic models is on diagnosing the location of the performance problem.
