Abstract

This research focuses on using Business Process Reengineering Best Practices in order to improve the purchase request of TAM as an EPC Company, revealing their impact on performance indicators of time, cost, quality and flexibility. This study aims to redesign the Purchase Request process, using Sharp & McDermott methodology. First, the process map is depicted considering APQC-PCF standard and SAP Solution Composer tools. Purchase request process was chosen to be redesigned due to TAM strategies as an EPC Company and the main drivers extracted by monitoring the process regarding the enablers. In order to depict the as-is and to-be models, BPMN standard and Bizagi Process Modeler tools have been used; However, because of the necessity of speed and agility in the process, time has been considered as the most important criteria and the to-be process has been modeled so as to accelerate the process. 12 candidate best practices include order type, task elimination, triage, parallelism, exception, numerical involvement, case manager, extra resources, specialist-generalist, control addition, integral technology and task automation. The selection of these best practices was done regarding literature review, monitoring the process and interviews with TAM experts and managers. The expected impact of BPR and each best practice has been shown on time, cost, quality and flexibility. This case can be studied and referenced so as to clarify the proper use of BPR best practices on one of the core processes of an EPC Company.
