WAF – WPC Project Goals *Reliable, consistent method for opening WAFs (consistent by shop and boat, by tagouts and non-tagouts…) Standardize process Standardize WAFs Reduce WAF Process/Scheduling/Review Time of General Foremen and Supervisors (with consideration to emergent work)
WAF – WPC Project Scope Regular refits with consideration of ERP’s TRF Work Only (includes TRF Alts) From the point of the job loaded and screened to the point of the WAF (Work Authorized) From the point of Work Complete to the point of the AWR signed off. (handle variation?)
A systematic approach throughout an organization to: –Specify value by specific product –Identify the value stream for each product –Make value flow without interruptions –Let the customer pull value from the producer –Pursue perfection Source: Lean Thinking, Womack & Jones, 1996 Definition of Lean Thinking Product: Anything that flows from input to output.
Lean Overview VA vs. NVA Value Added Activities (VA) Activities that transform materials into the finished product Customer willing to pay for Non-Value Added Activities (NVA) Activities that take time and resources (Waste) Customer is NOT willing to pay for Need to eliminate or minimize

Lean Overview Cycle Time One of the most noteworthy accomplishments in keeping the price of Ford products low is the gradual shortening of the production cycle. The longer an article is in the process of manufacture and the more it is moved about, the greater is its ultimate cost.” Henry Ford, 1926
Types of Waste Defects: Rework or Scrap Overproduction Inventory Waiting of parts/people/machines/paperwork Transportation of parts/people/paper Extra processing Motion of people/machines Unused employee ideas

Quality at the Source Places responsibility for quality on the worker doing the job Promotes doing the job right the first time Pass Fail
Point-of-Use Storage Raw materials stored where used Frequent, small shipments from vendors Requires trustworthy workforce Simplifies physical inventory tracking
Batch vs. One Piece Flow 10 minutes Batch & Queue Processing Lead Time:30+ min. for total order 21+ min. for the first piece 10 minutes Process A B C 12 min. for total order 3 min. for first piece Process B A C Continuous Flow Processing
Setup Time The time from the last good product of the previous run to the first consistently good product of the next run. Gathering necessary items Exchanging parts Positioning parts Making adjustments
Pull System / Kanban Make to Order versus Forecast. Signals (Kanbans) communication tool for production. Producing at the rate of the customer buying the product.
Takt Time Calculation = Takt Time Time Available Demand Example: Time Available = 25,200 seconds (one shift) Demand = 200 Gold Buzz per day Takt Time = 25,200 200 units 126 seconds == 2.1 minutes
