  1. Zero Defect - Debate

    Hi Rajesh, Thanks for your input. 1. Cars - Is there any news saying a brand new car within lets say, 50 kms wear and tear has issues like fires, etc.? No. It happens due to its rough handling or as part of its own wear and tear mechanism. 2. w.r.t electrical work - due to special causes, the variations in the process can happen. but it is not happening in all the process. The point here is if the builder uses low quality product, the defect can happen. Can you please compare the frequency of shocks at home material and with big big organisations? Good quality material, good manpower, high inspection rate, good quality assurance systems in place will eliminate the errors and the waste involved by achieving first time right concept. 3. ATM - Good narration. i)there are good security systems and mistake proofing enabled to reduce variations, waste and eliminate defects. ACID is a new term which i learnt. Thanks for it. But if no one has raised any concerns and no money actually detected from account, how will the bank be able to do continuous improvements? The bank might be in a position, that they think the process is 100% defect free. Also, power fluctuations happen, immediately the power generator starts and the service continues. Also the severe fluctuations is not in the organisations control, which is out of control. whatever is within control, the power backup is possible, and that is what we see in the ATM's as well. ii) Failures are often a stepping stone to success. We must have heard this. Yes. Often frequent trials help us implement lots of wonders. Human beings with proper training, continuous monitoring, regular assessments for failures and potential failures are studied to eliminate the defect. In summary, the zero defect is possible only with regular process re-engineering.
  2. Zero Defect - Debate

    Hi Sathya, So, you mean to say that out of 10 flight landings on a given day, we get one crash per day on a regular basis, because human can go wrong? Everyday, one patient dies of cardiac arrest when he had gone for a simple tonsillectomy procedure? Never, with regular practice, frequent upgradation of the system in terms of knowledge, technological advancements, etc, the errors are at the zero level. With continuous monitoring, application of process maps in order to eliminate the waste and minimise the defects, the zero defect concept is possible.
  3. Zero Defect - Debate

    Hi Vastu, 100% right.
  4. Consumer's risk

    Producer's risk - Good lot rejected due to sampling error.(Type I Error) Consumer's risk - bad lot accepted thinking it is good.(Type II Error) Rule : if d<=c, accept lot, else reject lot(c- acceptance number, d- defectives in sample) In summary, type I error is falsely inferring that something is there, when it is not present and type II is vice versa. As per the question, when the consumer rejects the bad lot, the producer's risk will increase. Its true. When the correct decision is not made on rejecting or accepting the lot, the consumer might be in risk if he selects a bad lot or producer will be in risk if the right lot is rejected. Eg. Type 1 - blood test wrongly detecting a disease when patient is actually not having. Type II - Blood test fails to detect when the patient is suffering. in another scenario, if the bad lot is selected by the consumer and gets affected, then the product in the market will lose its quality, brand name and its position. Hence the consumer's risk increases which also increases producer's risk. thanks Kavitha
  5. Zero Defect - Debate

    Hi Sumantha, thanks for bringing up your experience. Even in your statement, u had mentioned when it was trial the error had happened and not nowadays. That's what we call it as continuous improvements. In design for six sigma (DFSS), most of the organisations would implement the design as a pilot study in sample group, confirm the results, create prototype and then go for bulk manufacturing if there is no or minimal waste. Also, as rightly said by Atul, variations are always identified and solved using six sigma methodology for any process if you have heard. If any organisation wants to build high in market, then the opportunity for improvements is made visible to them by the teams internally, which is called "KAIZEN".
  6. Zero Defect - Debate

    Hi Rajesh, if you buy a car, do they possess defects? Never. Even after the design phase, the organisation will do test drives to confirm if the design is successful, then they go on with bulk production. in such cases, is 100% defect free product not delivered? While building a house, the electrical work done is successful without any defects. No free wires hung anywhere is only to prevent shocks and error proofing is applied in terms of switches. is that not 100% zero defect service? As Atul stated, in ATM machines, the amount whatever we enter only we are getting. We are not getting less or excess. only in terms of fund insufficiency, the ATM will not be able to deliver cash to the customer. Is it not zero defect service? There are products and services that are achieving zero defects in their work place to delight their customers.
  7. Zero Defect - Debate

    Hi Atul, 100% correct.
  8. Zero Defect - Debate

    Hi Karthik, Yes. Zero defect is always underlined with doing things first time right as you said rightly.
  9. Zero Defect - Debate

    Hi Sir, Yes. In terms of value, what is considered today is not value tomorrow due to tech advancements. That's why we require a team who can proactively work upon the market advancements and incorporate changes to the system wherever required. Operational excellence or process excellence team should also work as a change leader and any organisation should welcome the change upcoming for the growth of the organisation. Also, if you see any business, that will not have very frequent updates in the system. Any business would undergo process maturity levels and then optimize.
  10. Zero Defect - Debate

    Hi Ronaq, When there is a waste, the defects would be huge. i agree to the point that if there are no defects, it would never require any investment. You say that most of the organisations work at 3.4 DPMO. so if the aviation or hospital at surgical set up works at 3.4 DPMO in all the cases that they handle would we agree? If we don't agree, why is it so? why are we expecting zero defects?
  11. Zero Defect - Debate

    Hi Sumantha, As Vastupal said rightly, the defect car is not produced continuously. knowing that the defect has happened, any organisation would die to implement some of the six sigma tools like RCA, Poke yoke, etc to rectify the mistake knowing the error is costly. I agree with the story that they recalled the cars due to its possessed defects, but they did not produce the same knowing that zero defect is not possible. They would have definitely worked towards achieving zero defects since the damage to the users of the product is high, if the product possess any defect.
  12. Zero Defect - Debate

    Hi Ronaq, I understand the question. thanks for explaining it again. but my argument here is even in the slogans, we had two different statements- one supporting zero defect and another against zero defect. Just to remind ambassadors who are not supporting the zero defects achievable - it is achievable. the question is about possible or not? it does not talk about the cost involved in achieving, technology, six sigma tools, etc. Hence my argument is zero defect is definitely possible, with all employees motivated and engaged in doing things first time right, quality assurance with high inspection quality, technology to identify and correct the errors automatically with good amount of cost investment. thanks Kavitha
  13. Zero Defect - Debate

    Hi All, Good to see the hot discussion. @ Rajesh R - in the previous questions, most of us answered saying with employee engagement and motivation, acheiving zero defect is possible. but now arguing it is not possible. ok. If you talk about SLA, then the customer requires your product with highest quality spec set by the client lets say >95% and 98%. But my argument is , if you consistently deliver a product with 100% quality which means zero defect, will the client not accept it? The client will be happy with the quality and service that we provide. If we consistently satisfy the customer, the sales and profit would increase. Overall, having zero defect concept is always beneficial to the organisation. It is achievable.
  14. Zero Defect - Debate

    Hi All, If you ask zero defect is achievable or not? my answer would be "Yes". As rightly said by Reena and Vastupal, with high quality assurance at the time of project start and effective planning makes the zero defect possible. Again, if you ask me zero defect at the very normal or affordable price is achievable, then answer is no. It is achievable only with high cost involving technology & tools like Mistake proofing, standard work,etc, will helps us detect defects, correct it and send it to customer. Zero defect is again possible, if Perfection is achieved through constant practice. For eg, In surgical set up, a senior most doctors out of practice, he is able to achieve perfection in surgeries that they do. Zero defect is achievable in a way we perceive things. Zero defect is something that doing the things first time right. Hence, in a practical situations and theoretically zero defect is not possible. and if high cost is involved in detecting and correcting defects then, zero defect is possible. simply to say, it depends on the situation we want to explore.
  15. ARMI / RACI

    Q 56. Though they seem to serve the same purpose, what is your preference between ARMI and RACI? Why? In the project management, whether the project involving DMAIC / DMADV methodology, the responsibility assignment matrix is to clearly defined to avoid role confusions. GRPI (Goals, roles & responsibility, Processes and interpersonal relationships to be clearly defined in the team work. ARMI – stands for Approver, Resource, Member and I – interested party. RACI / RACIS – stands for Responsible, Accountable, Consulted, Informed and Support RACI is one of the commonly used tool to breakdown the teamwork into doable tasks, and map to each of them that who is responsible, who is accountable , whom should we consult about the assigned task and whom should be informed about the task and its progress. This is in simple a responsibility assignment matrix. ARMI is similar to the RACI matrix, where it defines the level of support assigned to each of the stakeholder. RACI / ARMI Description R - Responsible The person assigned to the task. Simply doer. A task should have alteast 1 and maximum responsible person to carry out. A - Accountable Person who holds ownership of the task & responsible for its success / failure. He who approves or rejects the task if completed. The final decision is with him. Max only 1 can be accountable for a task. C - Consulted It is usually SME. The SME should be consulted before taking any decision of the task, since he can provide input or opinion about the task. I - Informed The person who is informed about the progress and it is one way communication. S - Support Support team may extend help to the project team in carrying out the task by the responsible person. A - Approver A person who approves each milestone and help the project team to proceed to next milestone R - Resource Person who has expertise knowledge or domain skillset that is required In the project. M - Member Member of the project team I - Interested party People who will updated on the progress of the project along with the actions or decisions taken. RACI or ARMI Procedure – 1. Identify all the tasks involved in completion of the project 2. Identify all the roles that are required to complete the project 3. Assign the tasks to each of the roles what they are upto 4. Ensure all the task has one accountable and responsible person 5. Resolve if any role conflicts are there. 6. Share, discuss and agree on the RACI matrix with the stakeholders before starting any projects. Step Project initiation Project execution project manager Business analyst Finance It/ Software developer 1 Task 1 C R C C I 2 Task 2 A I R A C 3 Task 3 A I R A I 4 Task 4 C I R A C 5 Task 5 A A I A C Variations of RACI RASCI – with S as Support RSI – Responsible, sponsor and informed RACIO – with o being omitted / out of scope RACI – VS with VS being “Verify” and S for “signatory” Which tools I would prefer and Why? Both the tools serve the same purpose of analyzing the stakeholder’s involvement and their level of support in terms of project completion. It is only the name that is different. 1. RACI involves all the employees from all levels of the company by providing training and involving them in projects. RACI helps the proper six sigma deployment in the company. 2. The entire six sigma program is governed and resources are allocated by one central authority to sustain the improvement. 3. RACI brings out the project efficiency and instills process improvement to the company. RACI equivalent to ARMI in terms of : RACI / ARMI Description Equivalent to R - Responsible Person working on acitivty M - Member A - Accountable Person with decision authority R - Resource C - Consulted Key person to be discussed before taking any decision A - Approver I - Informed informed about the decision I - Interested party Conclusion: Both the tools are same and the name is just that different. Both helps us to understand the roles and responsibilities of each member in the company or in the project. Both avoids the role conflicts. Both helps in define phase as a stakeholder analysis to understand the level of support required in completion of the project. Thanks Kavitha
