If you are looking for a clearly defined and explained set of customer service KPIs, this is the guide for you. Each KPI entry includes a full description, worked example, formula and typical data sources. Many of the definitions for more complex KPIs also include advice for dealing with common problems and mistakes. The KPIs included are part of the ROKS Express™ KPI selection approach, so are designed to integrate perfectly with other KPIs from the series ('Essential KPIs' books, or 'Getting Started with KPIs’ - the full manual for the ROKS Express™ approach). The KPIs in this book have been developed by Bernie Smith, founder of Made to Measure KPIs. Bernie has over twenty years experience helping companies grow and succeed through the effective use of performance measurement and practical improvement techniques.
