Value Stream Management:
Often, individual (uncoordinated) process components, so-called bottlenecks, prevent entire process chains from becoming circular. Value Stream Mapping (VSM) consists of the analysis and visualization of value chains or internal company processes. This helps to identify and eliminate bottlenecks. The idea is to deliver value from the customer’s perspective and to continuously improve the process chain by collecting and evaluating the value chain and information flow. VSM aims to help with the adoption of circularity principles alongside the value stream.
Type of tool: Guideline to execute internal and cross-company analysis of process chains
Short description of the tool:
It includes a PDF guideline on performing VSM, a MS Visio template for the VSM analysis and an Excel template if Visio is not available. A description on how to link MS Excel with MS Vision is also included.
- Knowledge about and access to internal material flow information
- Experience in MS-Vision or MS-Excel helpful
- Prior knowledge within Lean and process analysis advantageous but not necessary
- MS Visio (recommended program - Microsoft extension) or
- MS Excel or any other programm to create flow charts e.g. (non exhaustive list)
- Creately (https://creately.com/)
This tool supports you to:
- Perform a value stream analyis (using MS-Excel) which helps to identify bottlenecks
- Visualize process chains or internal company processes (using MS Vision)
Example use case:
A detailed description on how to use the VSM tool is descripted in the guideline on page 23 with the example of a PET manufacturing process. The PET manufacturing process includes pre-form injection, bottle blowing, labeling, quality control, granulation andpackaging. The analysed parameters were energy, water consumption, noise level, reject rate, transport distance, and scrape rate. Five improvement potenials were identified which resulted in three significant improvements in the key performance indicators scrape rate and idle time.
Tool guideline and access:
To access the guideline please follow the link below . To design and analyze value stream mapping, some software and add-ins exist in the market such as Microsoft Visio or creately. A simple template of value stream mapping in Microsoft Excel can be downloaded via the link below.
_ Guideline to link MS-Visio with MS-Excel
The upcoming guideline follows the in C-VSM introduced ideas, as well as new concepts, and applies it to the standardized VSM tool firstly mentioned by Rother & Shook in their book “Learning to See: Value Stream Mapping to Add Value and Eliminate Muda” and consequently defined under the ISO 22468. The use cases for this guide coincide with the use cases for the lean-centric version with the adoption of circularity, which targets the development of close and slow loops, as well as minimized waste and sustainable value chain. The following guideline targets a broad user pool, such that any user, like either an external consultant or an internal coordinator responsible for lean can assess and evaluate any value chain from a circular perspective, whilst simultaneously pursuing a continuous improvement process.
