Week 4 Mapping the Value Stream Flashcards
Second principal of Lean
Map the Value Stream, a key tool.
Once you know what value is, the next step is…
to find out where it comes from and, consequently, where it does not occur.
In mapping the value stream, we will…
map all the activities that contribute to delivering the product or service from end to end, from supplier to customer�
Value stream map is… (2nd lean step)
a single tool that identifies value, shows you the waste, communicates the process, and focuses your efforts.
When implementing Lean, especially at the organization or enterprise level or the process level, it is strongly encouraged to… (2nd lean step)
do the value stream map step immediately after identifying value
One good value stream map can…
generate the information necessary to drive many kaizen events, large and small
What is a process?
a repetitive and systematic series of steps or activities where inputs are modified, or transformed, into what we hope will be value-added outputs that the customer is willing to pay for.
(the steps connecting input and output)
Three perceptions of a process (which is focus)
- What you think it is.
- What it actually is (one to focus on)
- What it should be
Why do we need a process focus?
Understand how and why things get done:
• link our customer and supplier relationships
• do more with fewer resources without compromising quality.
• see the process as it is, understand what is contributing to the issues we are seeing (main focus)
• Stop blaming from people to process
- Tip: if you give your people better processes, then you will get better performance from them.
Give a process a name.
Voice of customer vs. process
• Voice of the customer
- Set specifications, targets, and requirements
- The customer tells you what they will tolerate, and what they will not
• Voice of the process
- Cycle time
- Defects
- Waste
Lean focus is on both…
Lean is focused on process but needs to be connected to the customer.
6M’s to facilitate brainstorming are…
Identify sources of variation, ask about all of them: “ what is it about man in the process”
- Man
- Machine
- Material
- Method
- Measurement
- Mother nature
4 Main flow chart symbols
Current and future state
• Oval – starting or ending point in the flow chart
• Step – a rectangular box, usually a process step
• Decision diamond – usually a yes/no scenario (exception handling, right)
• Connector – a circled letter, or possibly a number, indicating its match on another page
Flow chart drawn in columns is a ? (give MPD example)
Swim lane flow chart Examples of MPD columns: 1) artist/creative 2) agency 3) printer 4) MPD 5) end customer
Flow chart in columns is a ? (give agency example)
Swim lane flow chart Examples of agency columns: 1) customer 2) agent 3) insurance rep 4) underwriter 5) customer service
Value stream mapping 3 rules
1) simple basic; 10-15 steps
2) each member creates their own mapes
3) train how the map is to be created
Value stream mapping process
1) Educate the team on how to create a map
2) Initial Brainstorm
3) scope the project
4) complete a waste walk
5) rough-cut map, final and current state
