My take to the string of the discussions is as follows: yes, YB - GB - BB is the three levels to showcase the degree of display of Six sigma tooling and the impact of the project delivery. there is QNI ( Quality Net income or Savings ) to quantify the outcome. The person to sign off the launch of the project is typically the program Owner...generally Vice President ( Operations ) level who would have communicated to the program/ process champions the focus areas and pain areas needing process improvement. The overall Six Sigma initiative has to be Top driven to realize benefits and momentum in continuous improvement. Parashurama

Dear Mayank Gupta: What the time tracker will do is to measure the Log in hours by populating the check out time minus check in time. what you mean to find is probably the TIME ON SYSTEM.....active production hours. this will exclude all those elements which goes in BREAK TIME ; Breifing Time ; Training Time ; Meeting Time ; etc etc. which are either an investment on time by training/ breifing/bio breaks or disinvestment of time by distressing ; discussions ; smoke break whatever. Therefore...Log in hours - ( all the disinvestment times + investment times ) = Active production time or Time on system Total number of transactions or number of calls resolved divided by the total active production time will be equal to the productivity of the day. if you decide to move on to hourly traction , you may have this set of measurements set up done for every hour...giving hourly productivity. It will be interesting to know some section of the day will be highly productive and some sections very unproductive. the discussions call roll from here with more insights. hope , this is making some sense.

Dear Manik: Mr Vishwadeep Katri has explained well giving an all round prolific response. There are two parts to your question...what is Six sigma and DMAIC. Six Sigma .... is supposed to co note 6 times sigma...where in sigma is the variations within the data set. data is therefore all important. Six sigma process ...denotes the process with less than 3.54 defects per million opportunities. You may have processes capable to deliver less than six sigma , infact mostly all process deleiver less than 3 sigma level. Unless and untill we exert to reduce process variations to allow fitment of almost all probabilities to fit in the normal curve ....thats the objective. with discrete data and by visible causative improvements ..one can experience an improvement from below 3 sigma levels to 3.9 sigma level. For process to be capable to deliver in levels > 4 sigma, we need data metric to be continuous to all tests / studies validations be done under normal distributions and easier to manage. DMAIC is a roadmap for the improvement journey...define-measure-analyse-improve-control. The discussion will go a long way.....cannot sum up in simple terms without further interactions. Let me know , if you have more questions . Parashuraman
