Estimate the cycle time needed to complete each step in the process map. Cycle time is the time needed to complete a specific process step. See Figure 3.7 on page 36.
Calculate a First-Pass Yield (FPY) for each step in the process and the overall process FPY yield. See page 37. The FPY is simply an estimate of the percentage of time that a process step is performed correctly the first time. Examples: Checking in with the receptionist, completing a PHQ-9 depression screen, having vital signs taken. The overall FPY is calculated by multiplying each individual step FPY (see Figure 3.8 page 37).
Evaluate Value Added (VA) versus Non-Value Added (NVA) activity for each process step. Carefully read the section “Identify Waste” in Delisle “Executing Lean Improvements” Chapter 2 pages 17-27 . Identify 3 key categories of VA and NVA based on the definitions in this section:
1. “VA activities” = activities that performed during the production or delivery of the service that increase it’s value to the customer.
2. “NVA required” = NVA activities performed during the production or delivery of a service that use time and resources but do not increase value to the customer, but are required due to legal, regulatory, accreditation or other requirements.
3. “Waste” = NVA activities performed during the production or delivery of a service that use time and resources but does not increase value to the customer and is not required for legal, regulatory, accreditation or other reasons.
a. There are 8 types of Waste using the mnemonic DOWNTIME (see pages 17-27 in Delisle)
i. Defects
ii. Overproduction
iii. Waiting
iv. Not utilizing peoples abilities
v. Transportation
vi. Inventory
vii. Motion
viii. Excess processing
