The field of Human Performance Technology (HPT) is very process driven when it comes to evaluating people performance. Professionals in this field are known more commonly as performance consultants (PCs). Judith Hale, expert in the field of performance consulting has stated in her book The Performance Consultant's Handbook that PCs are professionals who:
- "Are experts in analysis and measurement and provide expert advice, yet also facilitate the client's commitment to taking responsibility for supporting performance
- Play multiple roles
- Are not predisposed toward a particular solution and do not make recommendations until there are data to support them
- Facilitate conversations in ways that keep clients focused on what matters and develop meaningful information and insight
- Focus on outcomes and measured results".
