Process Analysis Flashcards
When do you perform process analysis?
a. validating a process
b. Defining/document a process
c.identifying process variables
What are the core characteristics of a process that we focus on at Penske?
a. Speed
b. Accuracy
c. Capacity
d. Cost
What is a process?
a. anything that is done more than once
What are the three types of process maps used at Penske?
a. Alternative
b. Flow
c. Swim Lane
What are the three relationship tools we use at Penske?
a. 5 whys
b. cause and effect matrix
c. fishbone diagram
The preferred method of defining the As-Is process is to:
a. Validate through observation
Why would you ask probing questions when analyzing a process?
a. Identify sources of variation and alternative processes within the process.
b. Identify decision points and decision inputs.
What is a COPIS?
*High level process map connecting the customer to the process
*View of process from 10,000 ft.
*Focus is from customer’s perspective
*Typically done in the define stage of DMAIC
What is the value of a swim lane process map?
shows different hand-off and responsibilities within a process
5 Why’s
Helps to drill down an effect to the actual cause
Fishbone Diagram
Helps to visually display potential causes for problem. Particularly useful when little quantitative data is available
What is the Pareto Principle and why is it important?
-Typically with most process 80% of all defects come from 20% of all causes
-Helps identify the vital few from the trivial many
Cause & Effect Matrix (Appendix)
Used to help narrow and prioritize a list of suspected X’s (inputs) down to a more manageable list
Value add
Value enabling
Non-value add
Value add - done right the first time, changes the product, customer is willing to pay for it
Value enabling - supports VA, required
NVA - Waste
