BP Modelling and Redesign

Question 1

What are the phases of the BP redesign lifecycle?

Answer 1

1. Process Identification - the process
2. Process Discovery - AS-IS model
3. Process Analysis - Problems and weaknesses
4. Process Redesign - TO-BE model
5. Process implementation
6. Process Monitoring and controlling

Question 2

What are the 2 process improvement methodologies?

Answer 2

Lean and Six-Sigma

Question 3

What is the difference between the two process improvement methodologies?

Answer 3

Six-sigma assumes that there is a problem with with the process that needs to be fixed.

Lean on the other hand does not address a specific problem with the process, but rather optimises the working process by removing waste (i.e be lean).

Question 4

What are the 5 phases of Six-Sigma?

Answer 4

1. Define - project plan
2. Measure - current measures, as-is process, etc
3. Analyse - data, root causes, etc
4. Improve - find solution & implement
5. Control - validate benefits & control new process

Question 5

What are the 3 tools the Lean methodology uses?

Answer 5

1. 8 wastes
2. Cause & effect
3. 5’Ys

Question 6

What are the 8-wastes of the lean methodology?

Answer 6

1. Defects
2. Overproduction
3. Waiting
4. Non-utilised potential
5. Transport
6. Inventory
7. Motion
8. Extra processing

Question 7

What is the difference between obvious and hidden waste?

Answer 7

Obvious waste is reduced in the improved process but is still there to some degree.

Hidden waste on the other hand is eliminated completely in the improved process.

Question 8

Why would one use a fishbone cause and effect diagram?

Answer 8

It is a great way of identifying the many small errors/mistakes/causes that led to the problem in question.
