Consulting – Taguchi’s Loss function

Myth: Any outcome between the customer specification limits considered as equal form the customer perspective. For example customer queue time in a bank is between 15-30minutes, as per this myth the customer who is been served at 15 minutes and another customer at 30minutes is received the same quality from the bank perspective as both of them are service within the agree time.

Reality: The quality of service/ product will be of not equal from the customer/ society perspective as it goes away from the target value even though it is within the agreed specification limits.


Justification: Taguchi one of the well-known statistician / engineer developed a representation that measures the financial impact of loss to the society if the product/service deviates from the target value. The representation is termed as Taguchi’s Loss Function. In conventional methods the Cost of Quality is measured considering the number of products rejected or reworked. In this method it is difficult to differentiate the cost of quality if the two products properties are within the specification limits but vary from each other.



From Taguchi’s perspective the loss function is as below. The graph depicts the lross function as a deviation from the target value of a product parameter. The parameter could be a diameter, color, density, hardness any other critical parameter of a product. From the service perspective the parameter could be cycle time, communication, responsiveness etc.

UST – Upper Specification Tolerance, LST – Lower Specification Tolerance




Taguchi believes performance begins decreasing gradually as the design parameter deviates from the target value even though the parameter value is between the LST and UST. Therefore, Taguchi proposed that the loss function be measured by the deviation from the target value. The loss function is
L = K * (Y – M) ^ 2
·        L is the result value of the function, generally measured in monetary units
·        Y measured value
·        M target value
·        K is a loss coefficient (Convert into monetary values)

Example: A company produces a part that has a diameter of 0.5 inches + or - 0.01 inches of tolerance. Failure cost of a rejection is $45.00. There are 30 units produced and the actual diameter is as below. Calculate and compare the loss considering the convention method as well as Taguchi’s loss function method.

Six Thinking Hats

'Six Thinking Hats' a tool created by Edward de Bono is an important and powerful technique used for decision making. This tool helps in thinking outside the normal styles and guides you to consider the rounded view of a situation. This is a very simple technique and easy to use, effective parallel thinking process that increased the productivity.  This tool, once learned can be applied immediately!

This technique is build based on the principle of parallel thinking which means at any moment everyone is looking in the same direction and the direction is been changed until we reach the decision.
Six Thinking Hats technique can be used in meetings targeted for a critical decision making. Each hat is a different style of thinking as explained below:
White Hat
·     Neutral and objective, Focus on the available data
·     Learn from the information that is available
·     Analyze past trends from historical data
·     Exclude opinions, feelings etc.,
·     Questions
o   What do we know? What is missing? What would we want to know?
·     Facts can be of two levels
o   Believed facts, Verified facts
Red Hat:
·     Emotional and angry
·     Look at problems using intuition, gut feelings
·     Understand the responses of people
·     Don’t expect any logical reasoning’s for the feelings and justifications
Black Hat:
·     Consider all the negative points
·     Be cautious and defensive
·     Make your plans 'tougher' and more resilient
·     Spot flaws and risks before the actions
·     Logically negative – Why this won’t work?
Yellow Hat:
·     Best case scenario
·     Benefits
·     Think positively
·     Have an optimistic viewpoint to see the benefits
Green Hat:
·     New ideas, concepts, creative solution
·     Alternative solutions
·     Growth and fertility
·     Stands for creativity
·     No criticism of ideas
Blue Hat:
·     Cool and sky above
·     Control the decision making process
·     Move Green hat in case we are running out of ideas
·     Move to black hat in case of contingency
·     Organizes the thinking
How to use the hats:
·     Use any hat as needed and it can be more than once
·     Sequence can be decided before the meeting or it can be evolved as we progress
·     Not necessary to use every hat for each decision making situation
·     Keep the time under each hat as short
·     Ensure discipline from each person and can have ground rules set before the meeting
·     This tool can be used by individuals and groups
·     Most used scenario - Open with a blue hat and end with blue hat
o   Open with blue hat
§  Why are we here? What are we thinking? What is the objective
§  Definition of the problem/situation
§  End state, Background or context
§  Plan the hats sequence
o   End with blue hat
§  What did we achieved
§  Outcome/Conclusion
§  Solution/Next steps
Summary:
Blue – Control & Organization of thinking process
White – Objective facts and numbers
Red – Emotions and feelings
Yellow – Hope, Positive
Green – Creative and lateral
Black – Careful and cautious

Lead Without Title (LWT) - Book Notes

This article is created from the understanding/learnings from the book named “The Leader Who Had No Title” by Robin Sharma. This note presents the learning from the book in the way that I understood while reading this book.

·    Lead without title (LWT) – to achieve this need to follow five rules represented in acronym called IMAGE

·        IMAGE
o   I – Innovation
o   M- Mastery
o   A – Authenticity
o   G – Guts
o   E – Ethics

·        I – Innovation
o   Making this day better than yesterday
o   Great careers and great businesses are built by evolution and not by revolution. Slow and steady improvements that don’t look great in isolation becomes evolutionary over time with massive gains.
o   Daily ripples of superior performance add up over time to a tidal wave of outrageous success.
o   This can be done by anyone no matter what their career/lives
o   Dream big yet start small and start now
o   Small steps over time generate big results and at the same time the failures in case any do not lead to disaster.
o   Like adding small amounts in bank from the childhood would give significant returns in the young age by the magic of compounding
·        M – Mastery
o   Committing yourself to mastery at what you do – whether your craft is selling staplers or educating children
o   Be so good that people cannot ignore you – by comedian Steve Martin
o   People said a structure i.e., Washington Monument this visionary could not be built. But the architect Robert Mills got the job done no matter what.
o   “Nothing less than my very best” that’s what mastery
o   Expect more from yourself than anyone around you could ever expect from you
o   Our goal here, each and every day, is to be the best in the world at my craft and that’s how we continually move closer toward mastery.
o   Every world-class expert has invested approximately 10000 hours (i.e., approx. 10 years) polishing their skills – from the Harvard Business Review article  ‘The Making of an Expert’
o   Beginning is hard – Space shuttle uses more fuel during its first three minutes after liftoff than during its entire voyage around the earth.
o   A practical tool to use is ‘The Daily 5’ – Doing 5 little yet important focused acts every day to get you closer to your most important goals
·        A – Authenticity
o   In this radically new period of business, your ability to have an impact and make a contribution comes more from who you are as a person than from the authority you receive by your placement on some org chart
o   Be who you are and say what you feel because those who mind don’t matter and those who matter don’t mind – by Dr.Seuss
o   Don’t lose yourself on the way to top – by Jack Welch
o   There will never be a better than you – by Warren Buffett
o   Being authentic isn’t just being trustworthy, staying true to your mission and values, and speaking honestly. It’s clear that you are also saying that being authentic means realizing all my potential and really getting to know all that genius you said was inside me.
o   When you give yourself permission to be open, real and brilliant around others, you give others permission to be open, real, and brilliant around you.
o   Authenticity about being true to who you are , even when everyone around you wants you to be someone else – by basketball great Michael Jordan in the book “Driven from Within”
o   Rather than defining their success by what they get, Leaders define their success by what they give
·        Guts
o   To have guts to see the opportunities where others see challenges and to envision things becoming a whole lot better while others grow complacent it to become a visionary
o   Criticism is the defense reaction that scared people use to protect themselves against change
·        Ethics
o   You will never go wrong in doing what’s right.
o   Leadership success lies at the intersection where excellence meets honor
o   How well you make your sheets determine how well you’ll sleep in your bed
