APPLICATION OF VALUE STREAM MAPPING ALONG PRODUCTION LINE OF PASTA MANUFACTURING COMPANY (A CASE STUDY OF GOLDEN PASTA COMPANY, LAGOS

Abstract

This work uses lean approach of wastes elimination through the application of Value Stream Mapping (VSM) techniques. It focuses on the analysis of the current state mapping of a particular company (Golden Pasta Company) to identify value added activities and non-value added activities, carry out problem solving techniques to eliminate the identified wastes and then proposes a future state map, operate and evaluate performance using the future state map. The manufacturing operations of Fava Long Goods 3 (FLG3) production line of Golden Pasta Company (GPC) was carefully understudied. Data collected from the company’s Enterprise Resource Planning system (ERP) and shop floor including feedback from the customers were analysed and evaluated. The results of the evaluation of these data were used to derive the Value Stream Mapping parameters for the developing the current state map and exposure of pasta manufacturing activities that accumulated to wastes generation. A Kaizen Blitz, a lean improvement workshop were held at the workplace where improvement suggestions were made towards the elimination of the wastes. The improvement suggestions were approved and implemented using a series of Value Stream Mapping techniques such as 5S, Kanban pull system, Supermarket pull system, Single Minute Exchange of Die (SMED), Kaizen idea sheet, Lean implementation tracking sheet and root-cause analysis to remove all the identified wastes. The results of the lean implementation shows that Production Lead Time (PLT) was massively reduced from 34.4 hours to 5.04 hours with a 85.3% waste reduction. A practical approach of implementing the value stream mapping, using Microsoft Visio 2016 software was suggested. An actual cost savings of N158, 515,200 was realised after third quarter (nine months) of lean implementation between September 2016 and June 2017. This was revealed in the Financial Statements of Accounts approved by the General Manager/Director of the Golden Pasta Company
