Hello Vishwadeep, One of the interesting dumps we have created is the possible data type in the portal. (I will down load and share with all).The toll gate reviews are specifically focused by MBBs for the type of data decision. It is amazing the thought of type of data and your instigation goes to various topics like correlation, distributions, chi-square etc I agree with you, it is tricky but a good learning. Thanking you once again Srinivas

Hi Kiran, The Attribute R&R Analytical is used when your response is Binary. Pls choose attribute agreement analysis (Stat/Quality Tools/Attribute agreement analysis). 10 operators with 3 trials and 20 calls will be 600 readings. If it is 20 operators you need 1200 readings. I am not sure how doable is this? Also the study should be conducted without the Quality operators knowing that this is being done otherwise we are introducing a bias. Thanks Srinivas MBB

Hello All, I have a different opinion. Control chart does not depend on the Company/Type of Business. It depends on Type of Project. Please look at the below scenario a) Defect reduction Project and the root cause was eliminated with a Mistake proofing. In this case Control chart is not applicable at all for Productivity Improvemnt Project by 15%. After implementation the productivity targets are revised by additional 15%. How do we apply Control charts Thanks, Srinivas MBB

Hello Rajesh, The regular Capability analysis output from Minitab will have the following a) Normal Curve with histogram All details of PPM, CPK, CP, Overall Capability and within etc If you understand histogram they are a good graphs that can show the spread but they have the basic weakness of time details. That is what time these incedences /defects occur. Infact Histogram is a same as control chart seen from Y axis. Also the subgroup pattern cannot be investigated Suppose you want to investigate outliers and you also wanted to know when it also occurred apart from knowing regular details you can use Capability analysis 6 pack in mintab. It has six packs of charts a) 2 charts so that you can investigate the time of occurence b)One run chart showing subgroup pattern c) Histogram with Normal curve d) Normality Plot d) One Graph displaying the comparison with Target versus actual Hope this clarifies. Thanks, Srinivas MBB Â Â

Hello All, I had the privilege to attend the Minitab 16 Webinar thought to share with all [*]1. Total 70 Changes in Minitab 16[*]2. Has a menu called assistant which is brilliant. It stops session window o/P and gives complete analysis report including interpretation of the results [*]3. The assistant is so user friendly and powerful that you dont have to struggle to chose the appropriate tool and the treatment based on type of data [*]4. Regression has new options that the equation gives interaction also [*]5. DOE has one option of 2 hard to change parameters [*]6. Conversion to Powerpoint/Word is very simple and no need to align [*]7. Johnson transformation is also moved to Normal Data. earlier the option was available in Capability analysis of Non normal [*]8. Capability Analysis six pack has Z values overall it has very exciting and time saving add on worth buying the upgrade license

Dear Vishwadeep, I would like to defer on Motorola failure as I was part of Motorola for a long period. Lean Sigma never existed at Motorola before year 2000. They were already hit by Iridium failure and Asian currency Crisis. Let us not deviate from the objective of "assessing the maturity the company has achieved on Six Sigma implementation. What are the key elements that you would like to study for this?" My Personal experience on a Company that had introduced Six sigma and Six Sigma was part of the DNA a) The Customer complaints become very predictable. Based on this month Weekly Quality review, we are able to predict the customer complaints most of the time b.) The Product Margins had almost quadrupled and we had a surplus of more than 15Million USD after all expenses ( Including Tax) for an annual business of 100Million USD consistently. The COPQ was < 2 cents per unit. The COPQ was $0.57 when started. c) Core processes in the company runs like Clock work with almost negligible/Zero fire fighting. Production Stopped due to any major errors was not experienced for 1.5 years (Wrong Loading, any Major errors etc). The Goals of DPHU was revised every Quarter on Quarter. Started from 7% to 0.20%. This unit had more than 7000 types of parts and More than 56 Major Processes before converting into final product. It had 3 special processes including Soldering, gluing etc. d) The headcount was the lowest when compared to the other 15 factories world wide with similar products e) Inventory Turns were more than 50 f) Customer base had gone up from 12 clients to 259 in 2 years. This was due to projects like SLA implementation once order booked up to delivery and Service g) USD50000/- was assured on each product if any equipment fail due to the this product and was a big USP h) Have penetration of metrics in all areas including challenging areas like how to measure Training effectiveness after training g) We had 3 months Goal program and Bonus was paid on Quarterly Achievements. The goals were both Common and Dept specific. Either we win as a team or Lose as a team To Summarize on how to access. Consistently evident raise in Margin due to Improvement Projects COPQ the lowest when compared to similar industry due to Six sigma implementation. The difference from the closest competitor should be significantly high Clear evidence that Customer base have increased due to the six sigma projects Every key deliverable area is clearly measured and improved month on month High CPK in Core Processes. The Trend of CPK is going high and has a strong relation to Customer Satisfaction Evidence of Applicable Sigma Projects is horizontally deployed. The environment is fearless and totally participative in case of any customer complaint Best Regards, Srinivas

Hi VK, My views are 1. It is a definite dent to Toyota Quality image. Quality was in Toyota DNA 2. I am not sure how external warning are transformed internally within Toyota to serious investigation and analysis 3. Japanese car are known for the quality across the globe. Today Toyota is like rest of the Pack. Customers are forgiving because of the past, but how long? 4. I am surprised by the response of Toyota executives with the blame game and scope goat type of excuse but not a single blame on the suppliers that is very courageous and different when compared to other top players 5. My personal experience with the plant of Toyota cannot be ignored. A) Limited automation Engineers are stretched with a lean and mean structure c) highly stretched operators with 12 hrs shift d) Not a free environment to work with e) this is further complicated with stiff targets both on Quality and Qty 6. We should also look at the benefits Toyota reaped so far. Lastly, The most efficient system is the most unstable system if one weak link breaks. My views are also stongly on the complacency that what worked in the past and will continue to do so

Hi VK, I am not in agreement for 3 days at all. 2 days should be adequate. This is because a. Lean conducting on employees at entry level is a liability and waste of time. This is my opinion b. if the partcipant is not aware of 5S principles, not through on inventory turns, Basic cycle time, Basic Tact time , Types of production ( Batch, Mass etc) , Type of flow (TPS), Process Mapping etc even 3 days would not be effective c) We should keep it simple not get into indepth details of each of the waste. The partcipants must be able to relate to the workplace I am absolute in agreement of not complicating with green/black belts etc. The production lines I worked were Motorola ( Pagers , 2 way radio& Phones) and A large US UPS Manufacturer . Both used single piece flow (TPS) and visual factory. It was greek and latin when it was first thought to us. None of us were benefitted nor applied. We could get into the waste identification and elimination only after 2 years of operation and formal re launch of lean culture Thanks

Hi The assumptions are Model is linear in coefficients, Randomness in all predictors, Average of residuals should be zero, no corellation within residuals, Residuals have constant variance, Residuals pass normality test, no corellation within input variables( Multi colinearity) VIF signifies the presence of multicolinearity that is correlation within independent variables or Xs. we dont allow >5, we operate with caution if it is <5 , we ignore if it is <1 Durban watson statistic indicate that residuals are auto correlated R-Sq, R,Sq Adjusted,R Sq predicted is answered Larger value of PRESS statistic indicate the model has strong predictive ability Unusual observation that does not fit the model. Usually guides us to rootcause and not Linear to the model cooks distance help us in identifying the effect of deleting an given observation Hope I pass the Quiz Srinivas MBB

Hi Kiran, Though your query looks quite simple, it is difficult to explain with out the understanding of certain basics of DOE. It would be easy if you had an oppurtunity to conduct an experiment and had the experience of DOE. It is important to understand the follwoing a) Confounding or Alias Resolution c) Two, three, four way interactions d) Blocking e) centerpoints Etc In a broad sense Factorial designs are applied mostly study mutiple factors at a same time and typical relationship is linear while Response surface is used when you suspect curvature Generally less factorial means certain treatment is missed out and the equation may not be accurate. Various methods are available to mitigate based on the cost of experiment and other constraints You can reach me at 9702777754. I was part of Motorola for 7 years Srinivas MBB
