In the beginning, Dr. John Man (Founder of SPI and Six Sigma Master Black Belt trainer and advisor, SSS) gave an introduction speech and he discussed how will groups be more efficient?
Mr. Daniel Ng (HTCIA/PTL) was the first speaker and he presented Quality Function Deploy (QFD). He explained Voice of Customer (VoC) and Level of Customer Satisfaction were two important element in employing QFD in product design.
One of life examples was consumer electronics.
Another example was tools for fruits.
Mr. Ng said QFD is the beginning of Six Sigma. There were four implications to Six Sigma Project below.
i) Upon prescribed customer focus, all selected SSBB projects were bounded with customer delight.
ii) Those high weighted processes are selected (e.g. Critical Business Requirements (CBRs)) for more accurate analysis.
iii) Specific measures were able to levy when collecting data against particular CBR.
iv) QFP acts an objective reference framework in late problem analysis, and solution proposition; all customer requirements are co-related proportion against process flow and critical business function.

The second speaker was Dr. Daniel K.C. Chan and his topic introduced Analytic Hierarchy Processing (AHP).
Dr. Chan said AHP was a multi-criteria decision making method which derive ratio scales from pair-wise comparisons. AHP was able to deal with quantifiable and intangible criteria. Then Dr. Chan used a car as the first example. The criteria were “Style”, “Reliability” and “Fuel Economy”.
The following diagram showed the second example – Investment Bank.
Dr. Chan concluded AHP was able to use in Six Sigma as follows:
· Assigning importance to Critical Customer Requirements (CCR)
· Assigning priority to Critical to Quality (CTQ) requirements
· Assigning importance in Quality Function Deployment (QFD)
· Various ratings in Failure Mode and Effects Analysis (FMEA)
Mr. Steve Kwong was the third speaker and his topic was “Process Mapping and Value Steam Mapping”.
First, Mr. Kwong introduced the different tools used in Six Sigma and Lean.
Then he briefed the 7 waste (7 Muda) included Over Production, Motion, Waiting, Inventory, Correction, Over processing and Material Movement. Then he mentioned the process mapping levels which included “Macro”, “Micro” and “Sub-process”.
The example of process mapping was showed.
After that he introduced the major area in the value stream mapping improvement included price, quality, reliable delivery, fast response to changing needs, etc.
The forth speaker was Mr. Danny Lai and his presentation named “Measurement System Analysis”.
Mr. Lai briefed a real case on using gauge R&R. It was because of the problem of oil leakage would cause burnt.

Mr. Lai briefed a real case on using gauge R&R. It was because of the problem of oil leakage would cause burnt.
Then a Photo-Hunt game was performed to demonstrate the variation of visual inspection.
The fifth speaker was Mr. Albert Lam and his presentation entitled “Capability Analysis”.
He explained a capable process was a stable process which demonstrated the ability to meet customer requirement.
He used two examples to explain the different of Cp & Cpk (for short term) and Pp & Ppk (for long term).
Vendor A showed “Not capable” (Cp and Cpk < 1) and “Not meeting specs” (Pp and Ppk <1).
Vendor B showed “Capable” (Cp > 1; Cpk ~ 1) but “Not meeting specs” (Pp and Ppk <1).
Mr. Lam concluded Process Capability told you whether you needed to
· Work on special causes (instability)
· Work on common cause (capability)
· Mover the average (target issue)
· Or some combination of the above.
Henry also introduced some on-line communication links below.
The sixth speaker was Ms. Judy Liu and her presentation was “Relentless Root Cause Analysis”. She said we performed root cause analysis to prevent turnbacks and customer escapes from recurring.
She used Ishikawa diagram (Fishbone Diagram) in 3 levels to evaluation the root cause.
There were five steps as follow.
i) The identified reason
ii) Search for cause (Brainstorming)
iii) List all causes
iv) Arrange causes (Affinity diagram)
v) Build root causes (Fault Tree Analysis – FTA)
The seventh speaker was Mr. Tony Lo and his topic entitled “Failure Mode and Effects Analysis”.
He introduced that FMEA was a systematic procedure for the analysis of a system to identify the potential failure modes, their causes and effects on system performance.
The FMEA Form with example was shown.
Mr. Lo mentioned that FMEA was team approach and started at early stage of product development. FTA was used to develop the root causes and FMEA form was living documents. It needed to review FMEA after actions were completed and verified. Moreover, review of FMEA was requested when process changes or new failure mode occurs.
Mr. Keville Krogh was the eighth speaker and his topic was “Validation of Root Causes Correlation”
Mr. Krogh had a fun excise with participants and demonstrated that correlation and dependence were any of a broad class of statistical relationships between two or more random variables or observed data values.

After the break time, MR. Henry Soo (President, SSS) introduced “The Hong Kong Society of Six Sigma Limited”. SSS aims to become the leading and reliable resource center for Six Sigma practitioners, enthusiasts and their organizations so as to strengthen the practical application of the Six Sigma breakthrough methodology that is internationally recognized and consulted.

Mr. Krogh had a fun excise with participants and demonstrated that correlation and dependence were any of a broad class of statistical relationships between two or more random variables or observed data values.
However, correlation did not imply causation. He summarized the correlation below. One thing should be remembered that “Does it make sense?”
The final speaker was Mr. T.F. Lam and his presentation title named “Solution Analysis”.
His solution analysis process was shown in sequence: Decision Tree Analysis, I AM WISE, Validation of selected solution, Force Field Analysis, Process Decision Program Chart, Validation Plan and Implementation Plan.
What is the meaning of “I AM WISE”?
I – Invention
A – Add Value
M – Maximize available resources
W – Win Win
I – Integrated
S – Savings
E - Extensive
One of life example was demonstrated.
I AM WISE was employed in the table form.
At the end, Dr. John Man moderated the Q&A session.
