Q

What is a swim lane diagram?

A

A process in which people who are involved in the process are identified, organized vertically, and marked with start and stop points to formulate process steps with a noun and verb. The process steps are arranged in actual sequence and marked for known waste points

Q

What is value enabling activities?

A

Is the business willing to pay?

21
Q

What is non-value adding activities?

A

Waste

22
Q

What are the types of waste or TIMWOODS?

A

Transport
Inventory
Motion
Waiting
Overproducing
Over processing
Defects
Skills

23
Q

When do you do a time analysis?

A

Only when the CTC or CTB is time related

24
Q

What do you do in a time analysis related problem?

A

Collect all relevant times for all process steps

25
Q

What is PLT?

A

Process lead time, from start to finish

26
Q

What is capacity?

A

The max output rate

27
Q

What is capacity the result of?

A

Processing time and number of operators

28
Q

How do you calculate capacity?

A

60 seconds
———-———— x total operators
seconds per unit

29
Q

What is a bottleneck?

A

Process step with least capacity or throughput

30
Q

What is a constraint?

A

Bottleneck that is not fulfilling customer request

31
Q

What is throughput?

A

Produced units per given time as is

32
Q

What is TAKTRATE?

A

Requested units per given time, to be

33
Q

How do you find the TAKTRATE?

A

Requested number of parts divided by given amount of time

34
Q

What is the TAKTTIME?

A

Given time per requested units

35
Q

How do you find the TAKTTIME?

A

Given an amount of time divided by requested number parts

36
Q

What are potential constraints?

A

Process process steps that might lead to not fulfilling the customer TAKT.

37
Q

What is Little’s law?

A

PLT= work in progress/exit rate

38
Q

What is lean focus?

A

A stabilizing process to reduce inventory and increase exit rate

39
Q

What happens when you reduce work in progress?

A

The process leadtime decreases

40
Q

What is process efficiency?

A

The need to identify improvement opportunity by comparison with industry and other benchmarks

41
Q

How do you find the process efficiency?

A

Value adding time
————————— x 100%
process lead time

42
Q

How do you find exit rate?

A

Pieces/time

43
Q

What is data analysis?

A

Splitting data according to different factors in order to find potential influencing factors

44
Q

What are the 4 goals of the analyze phase at the gate review?

A

Potential causes collected
Analyze the process
Analyze the data
Derive main causes

45
Q

What are the two verification doors that you need to choose between to verify your data in analyze phase?

A

Data
Process
