Process Analysis

Question 1

What is Process Analysis? What is the Output?

Answer 1

Process analysis focuses on identification, documentation and (whenever possible) quantification
(using performance measures) of the as-is process (es).

Output:

• structured collection of prioritized issues
• Insight on weaknesses and their impact

Question 2

Qualitative process analysis types

Answer 2

1. value-added (VA) analysis (to identify unnecessary steps of the process)
   - VA (Is customer willing to pay?) (Assess application)
   - BVA (Check validity of degrees, completeness)
   - NVA (Send, forward, notify something)
2. Waste analysis (to identify sources of waste)
   - Move (Transportation, motion)
   - Hold (Inventory, waiting)
   - Overdo (over-processing, over-production)
3. Stakeholder analysis (to identify and document issues in a process from multiple perspectives)
   - Customer
   - Process participant
   - External parties (Suppliers)
   - Process owner
   - Sponsors
4. Root-cause analysis (to analyze root-causes of process issues)
   - Issue (Right) –>
   - Why-why diagram (five why’s) (top)
   - Factors (left)
   - Cause effect diagram (bottom

Question 3

Flow analysis

Answer 3

• Allow to calculate performance measurements
• Capacity of resource utilization and as-is processes
• Processing time, Waiting time, Cycle time

Question 4

Querying analysis

Answer 4

Queuing analysis is a technique suitable for analyzing individual activities performed by one resource pool.
Can be used to analyze waiting times and cycle times

Disadvantage:

• Process simulation
• No cost and quality measurement

Question 5

Simulation analysis

Answer 5

– As-is analysis (What is maximum process performance?
Where are bottlenecks?)
– What-if analysis (How does a process behave with changing
loads or resources?)

Question 6

Queuing process

Why is it needed?

Answer 6

Input source —- (Queue + Service station) —- Output source

• Need to balance the cost of increased capacity against the gains of increased productivity and service
• Large costs of waiting and of lost sales due to waiting
