RECENT PROJECTS
These are the types of projects we've worked. You may find some similarities to your needs and you will see how we can synthesize solutions where traditional solutions don't always get there. Check our Blog for discussions on current projects.
PROJECT: Screw Machine Cpk
This project involved an engine component which needed capability improvement.
Background:
Capability is measured at final assembly. Measurement determines selecting mating components based on tolerance matching.
Part bodies are machined on automatic screw machines. There are 23 characteristics on each part body.
SPC is used to control each part body characteristic at machining.
Cpk at final assembly is below 0.9.
SPC charts are posted in a war room.
Characteristics have individual action plans for improvement. No improvement action has improved Cpk.
Solution:
SPC charts showed trends from characteristic to characteristic appeared to be correlated.
The individual characteristic trends resembled the individual trends of stocks in the stock market.
Using a Box-Jenkins Time Series Analysis (cross correlation study), it was demonstrated that over-control was being done. By limiting to three (3) characteristics under control, the over-control was corrected.
Results:
Capability improved to 1.3 Cpk.
PROJECT: Transactional Taxes
This project involved transaction tax minimization within legal regulations.
Background:
VAT taxes were applied for every accounting transaction of a product in the VSM.
VSM was thoroughly defined to highlight VAT liability points.
Laws were reviewed for VAT regulations. Regulations allowed for changes in transactions which limited VAT liability.
Solution:
Change the Value Stream, within legal boundaries, to minimize VAT liability.
Results:
VAT was reduced by $100MM annually through VSM restructure.
