    Nominal Conditions

    Vastupal Vashisth has mentioned the two requirements for setting up nominal conditions and provided a clear example, and hence is the chosen best answer.

    Stable vs Capable Process

    A stable and capable process can be rendered incapable "suddenly" if there is a shift or change in the specification limits. The chosen best answer is that of Manjeet as he provides two such examples. Devesh has also listed an example. Read through rest of the answers for a very concise review of capability and stability concept.

    The chosen best answer is Mathi's. He has provided a detailed description and a brief example. Suggested reading - Prashanth's answer for a detailed example and Mohiuddin's answer for how different levels come into play with Shojinka. Vastupal outlines some clear advantages of Shojinka. Every answer to this question has some unique points mentioned. Happy Reading (and learning!)

    CLOSED MITT vs 7 Wastes

    Faizel Ahmed's answer is the chosen best answer to the question for the detail and easily legible format for the comparison. Mathi and Owen's answers also provide a good comparison and are a good read.

    KNOT Technique

    As mentioned in the question, the KNOT technique is used when data collection during Gemba walk is not reliable. However, to solve any problem, data is the pre-requisite. The KNOT Chart is almost like a matrix that can be created using an excel file. The matrix helps classify all collected information into 4 parts. The information collected is used towards finding the root cause of the problem and taking corrective action (commonly known as RCCA - Root cause and Corrective Action). K stands for "Know" and is used for facts that have validated data or evidence; N stands for "Need to know" and is used for information that must be collected; O stands for "Opinion" and is used when someone provides an opinion and it may not be verified information; and T stands for "Think We Know" - this is also not verified information or data. All information classified under N needs to be collected in order to solve the problem, all information classified under O and T needs to be validated as well and should be changed to a K. The bottom-line is that problem solving can be attempted only when we have verified information and objective data. Additional information such as Owner, Evidence, Priority level etc can be added to the KNOT chart. This helps in identifying and tracking actions to be taken during the RCCA process.

    Creativity and Productivity

    The best answer is that of Babu Ramachandran. To know the expert view, read Venugopal R's submission. Creativity need not sacrifice productivity but can boost it to get the desired output and results.
  7. Avinash Modi has provided the best answer for the question. Kiran Kumar has rightly pointed out that both approaches are unique but can also be combined to drive overall improvement.

    Bells and Whistles

    Bells and Whistles can be compared to the excitement attributes in Kano analysis. Such features may become a distinguishing feature and hence create a niche in the market. Manjeet's answer is the chosen best answer with relevant examples. Rajesh and Avinash's answers also mention additional examples.

    Apples to Oranges Comparison

    This may have seem liked a textbook question to answer and there lay the complexity in answering the question. Thank you all for attempting to answer; R Rajesh has given some common business situations. We come across many such business situations - the one that we are all aware of is "pre" and "post" improvement comparison in a DMAIC project. Very clearly it is an apples to oranges comparison, as the process itself has gone through changes. This comparison is made possible by using indices such as Cp, Cpk, Pp, Ppk or Sigma Level. There are times when Balanced Scorecards across different divisions are compared - the metrics of the divisions may be completely different, hence an apples to oranges comparison. %age attainment to goal is another way this comparison can be made possible. One may also reason that accuracy rates, defect rates, coefficient of variation can also help make apples to oranges comparison.

    Hansei means reflection. It is a deeply internal process which can be done individually or in a group. The focus is not the mistakes, but what could have been done better. This focus leads to Kaizen ideas. R Rajesh's answer is the chosen best answer for this question. He has detailed out how Hansei is connected to Kaizen and not used the word mistake but terms such as retrospection, reflection and opportunity for improvement. These words indicate the true spirit behind Hansei.

    R Rajesh has described how Yokoten can accelerate learning and growth and how the lack of it can impede the learning and growth. This is chosen answer for the question.

    Run Charts

    Thank you all for the attempt in answering this question. There are no chosen best answers. Good luck for the next question which will be out soon.

    Without a WIFM, there is no urge for anyone to make an effort towards an improvement or to make any changes. It is, hence, appropriate for the GB/BB and the cross functional teams to ask for their WIFMs. It may vary from an individual to the next (monetary, learning, advancement, scorecard goals and hence business goals etc) - as it should because it speaks to everyone as "ME". The chosen best answer is that of R Rajesh for making an attempt to outline the WIFM from everyone's perspective while keeping in mind the note above.

    Robotic Process Automation

    RPA is rule based, follows a coded logic and can do repetitive tasks. Whereas AI is a step beyond RPA; and can mimic human behaviors such as cognition and reasoning and take complex decisions. The chosen best answer is for Ehtesham because of differences shown in lucid tabular format alongwith examples for both. The answer also has just the right detail that was asked for without any extra dimensions. R Rajesh's answer cites additional examples.

    Changeover Time

    Khalandar's answer provides the detailed steps followed for SMED. It is the chosen best answer. Chella's answer provides multiple examples from various industries and adds to the clarity on the topic. Chella's answer also provides application orientation for the concept in the service industry.
