Abstract
Value Stream Mapping (VSM) is likely the most common tool to represent and analyse the value stream of product families. However, it has several limitations, recognized by professionals and academics, namely in terms of identification of certain types of waste (activities without added value). The purpose of this paper is to present a VSM extension based on elements coming from a new type of representation and analysis tool called Waste Identification Diagram (WID), which is being developed at the Production and Systems Department of University of Minho. WID is able to represent, in an effective manner, information about several aspects, including wastes related with production and people, layout, available capacity and even economic indicators. The inclusion of WID elements within traditional VSM was successfully achieved, resulting in a VSM extension which is more effective than the traditional VSM, not only in the information provided but also in terms of interpretation easiness.
Highlights
In general terms, the clear understanding of the business and production processes is mandatory for any company wishing to diagnose problems and improve performance
A recent work involving a Value Stream Mapping (VSM) extension can be found in [13], where it is described an extension of value stream mapping through waste identification beyond the clients’ perspective
This work successfully introduced an extension of the well-known Value Stream Mapping (VSM) in order to overcome some of its limitations, especially in terms of ability to represent wastes and economic indicators
Summary
Flowcharts, SIPOC diagrams (Suppliers, Inputs, Process, Outputs, Customers), BPML diagrams (Business Process Modelling Language), VSM (Value Stream Mapping) and WID (Waste Identification Diagrams), but VSM is the most popular. VSM has some drawbacks (section 2.1) and to overcome these drawbacks, this work proposes a VSM extension using some elements of the WID diagram that is being developed at the Production and Systems Department of University of Minho. Two variants of the VSM extension will be presented: (i) the designated “VSM+WID” (section 3.1) and (ii) the “VSM+WIDe” (section 3.2). A list of criteria is used to assess the potential gains achieved by this extension of VSM based on WID and WIDe. The paper is organized is 4 sections.
