Creating a Value Stream Design (VSD)
Old Mindset vs. Lean Mindset
- Focused on machines and todays borders
- Manufacturing processes divided into manufacturing cells
- Focused on increasing machine output and not on customer demands
- High level of inventory and safety stock inside and outside the factory
- High level of buffer hiding waste (e. g. waiting time
- Process visualization based on green field planning
- No borders and barriers at all, focus lies on process interactions
- Planning according to a short lead and throughput time
- Visual Management based on a low inventory and stock level
- Visual Management = Quality Management
What is a Value Stream?
-
A chart visualizing the material and information stream -
Considers the entire supply chain including suppliers and customers -
Using predefined symbols like for Kanban box or supermarkets -
Points out all weaknesses of your supply and process chain and focus on your value adding activities
Detect Value and Waste
-
Go through your factory or your supply chain and capture all you see -
Decide for all you see weather it is value-adding or none value-adding, and whether it is necessary or not -
Sketch the value-and-waste matrix and sort all items accordingly -
The focus of your value-stream design must lie on the necessary value-adding activities. Eliminate all the rest
