Entity Flow-phase Analysis for Fast Performance Estimation of Organisational Process Systems

This paper describes Entity Flow-phase Analysis (EFA) which is a method for fast performance estimation of organisational process systems. Entity Flow-phase Analysis extends the approach of the promising Traffic-Flow Analysis (TFA) method – created for the rapid analysis of communications networks – for BP (Business Process) systems. EFA operates on the possibilities determined by the similarities between communications networks and BP systems and introduces new solutions for the problems that occur because of the differences between ICT and BP systems. EFA, similarly to TFA, uses the combined approach of simulation and numerical methods. In simulation projects initiated to support the design of Information and Communication Technology (ICT) system and Business Process (BP) system in an organisation the parallel analysis of different systems may be efficient. EFA is a promising evaluation method to be applied for systems with determined BP and ICT subsystems in an organisational environment.
