3. This is about a real project
... however times and numbers have been changed to
allow discussion and analysis without compromising on
confidentiality.
The webinar is first and foremost about PROBLEM
SOLVING – Improvement and problem solving is about
being humble towards those who acknowledge their
problems.

5. Appreciate data
Who sees data?
• IT people
• „Geeks“
What do the others see?
• „Percent on time“
• Average lead time
What are they missing?
• Insight
• Opportunities

>50 A/C per night >50 A/C per night
>100 trucks per night >100 trucks per night

About half is sorted in over 30mins

8. From problem to project
Starting point:
„Our problem is, we don‘t have that sorting machine.“
… But we don‘t want to buy that machine …
„So let‘s give the Lean Sigma guys a chance…“
Project opportunity:
„ Reduce rate of slow sortation from 50% to <10%.“

20. An important trick:
Calculate WIP from time‐in / time out
Column H Column I Column J Column K Column L Column M
Flow unit Time in Order Flow unit Time out Order
(hh‐mm‐ss) (hh‐mm‐ss)
A TA,in 1 … … …
B TB,in 2 X TX,out N‐2
C TC,in 3 Y TY,out N‐1
… … … Z TZ,out N
Largest “time in” that is
still smaller than a given “time out”:
SUMPRODUCT(MAX((I$2:I$20097<L6)*I$2:I$20097))

25. Treat your data like a „gold mine“
1) Collect trustworthy data
2) Analyse them with due diligence
3) Understand how to drive enablers
4) The result Y = f(x) will follow
