Business process management is a comprehensive solution for understanding and managing current process in your organization(through techniques such as writing or documentation of processes and workflow) and also helps company's' to simplify the complex relations existing among employers, systems and processes so that it is completely understandable to increase organization's productivity and customers' satisfaction. The presented study is about business process management and business process lifecycle and business process modeling language. Workflow process and process mining, process mining algorithms and process mining perspectives are investigated, as well as, clustering methods, advantages and disadvantages of each method are presented. Finally it will be introduced a strategy for using existing clustering algorithms in process mining for analyzing processes that change over time. Keywords: Business Process Model, Process Mining, Clustering, Change Over Time 1. Introduction In the recent decades, there have been arguments about processes and process inclination thought and process discussion. And process management is not a new discussion but industry of information technology and communications couldn't present a comprehensive and proper solution for analyzing, defining, implementing, controlling and optimization for organizational process before the emergence of modern technology of business process management. By the emergence of business process management, many practical researches have been presented from academic perspective and became feasible during these years, and information technology plays strategic role and showed its role in approving this technology(business process management) properly [2]. Most of changes happened in technology field causes improvement and growth(gradually) in the methods of doing works, but recently the emergence of a new technology we have seen essential and fundamental changes in business process field, like internet(or specially electronic web post technology) which one of these technologies. We believe that business process management is one of these technologies. Around 10 to 15 years ago organizations started system uniform especially in industry section, categorization by uniform and establishing process by tracking and data interchanging, events tracking, atomization of processes and their adaptation. Small company could grow significantly by company resources planning, management of relationships with customer sequential management of resources. 2. Case study investigation Business process management as a technology was introduced to the world of academy in 50s and 60s as frequent improvement in business process management approach of quality. Peter Finger and Harvard Smith attract business managers to process management and lifecycle in 90s. Current process in the organizations is complex, dynamic and frequently changing, developing in an irregular manner and is place differently in every system and platform. Management system aiming at atomization of organizational process lifecycle and business process management was presented. These kinds of systems try to manage the whole lifecycle of processes from modeling and definition to implementation of optimization by tools based on information technology which execute business process management lifecycle partially(not completely), moreover, other parts of this lifecycle is based on management International Journal of Computer Science and Information Security (IJCSIS), Vol. 14, No. 8, August 2016 1112 https://sites.google.com/site/ijcsis/ ISSN 1947-5500
