Value stream mapping
- 2. VALUE STREAM MAPPING DEFINITION • Value stream mapping is a lean-management method for analysing the current state and designing a future state for the series of events that take a product or service from its beginning through to the customer. • Special type of flow chart that uses symbols known as "the language of Lean" to depict and improve the flow of inventory and information. • Planning tool to optimize results of eliminating waste.
- 3. VALUE STREAM MAPPING PURPOSE Provide optimum value to the customer through a complete value creation process with minimum waste in: – Design (concept to customer) – Build (order to delivery) – Sustain (in-use through life cycle to service)
- 4. WHY ? • Many organizations pursuing “lean” conversions have realized that improvement events alone are not enough • Improvement events create localized improvements; value stream mapping & analysis strengthens the gains by providing vision and plans that connect all improvement activities • Value stream mapping & analysis is a tool that allows you to see waste, and plan to eliminate it.
- 5. USING THE METHOD 1. Planning and preparation. Identify the target product family or service. Create a charter, define the problem, set the goals and objectives, and select the mapping team. Socialize the charter with the leadership team. 2. Draw while on the shop floor a current state value stream map, which shows the current steps, delays, and information flows required to deliver the target product or service. This may be a production flow (raw materials to consumer) or a design flow (concept to launch). There are 'standard„ symbols for representing supply chain entities. 3. Assess the current state value stream map in terms of creating flow by eliminating waste. 4. Draw a future state value stream map. 5. Work toward the future state condition.
- 7. WHAT IS THE VALUE THAT FLOWS? • Price • Quality • Reliable delivery • Rapid response to changing needs
- 8. WHAT FLOWS? "ITEMS" flow through a value stream – In manufacturing, materials are the items – In design & development, designs are the items – In service, external customer needs are the items – In admin., internal customer needs are the items
