Abstract: In today's world, organisations are always interested in evaluating themselves. This self-assessment can present a common language and conceptual framework for the improvement and management of the organisations. In this paper, first the performance evaluation models including the European Foundation of Quality Management (EFQM) model and data envelopment analysis (DEA) are studied. Then, assessment data of 24 food companies are collected through an EFQM model questionnaire. Then the efficiency scores of each organisation based on the DEA (CCR) are calculated using Lingo software, in which that, organisations are considered as decision making units (DMUs) and enablers and results criteria in EFQM model are inputs and outputs of DEA model. Then, based on the efficiency scores of each organisation, improvement plan with the help of the dual DEA model is presented to increase efficiency scores of inefficient units. Finally, it will be clear that each inefficient unit for improving the inefficiency should focus on which of the criteria.
