Value Stream Mapping and process optimization strategy: A case study of public sector organization

Abstract

Value Stream Mapping (VSM) tool helps in identifying critical time lag factors in process functioning; a major deterrent in process efficiency. This research focuses on value stream mapping applications to restructure the service provision criteria in public sector organization in Pakistan. A public sector organization is evaluated for constraint effects and proposes the lean thinking strategy for optimization. Data components include receipts, passed and rejected bills and number of days for disposing of bill; collected and evaluated. Pareto analysis and cause & effect diagram are established to measure the roots and intensity of problems. Moreover, process capability is structured to assess the process performance and trend. Results exhibit that the suitable cataloguing necessitate for improvement, hence lean thinking approach is adopted to illustrate waste free processes; valuable for organizations. Optimization strategy is presented to enhance the performance of the process in concurrent engineering environment. © Springer-Verlag London 2013.
