Hi Mani, If you are using Minitab, you shall notice that use of process capability command provides you with Cpk and Ppk values for unilateral tolerances. This is feasible as Cpk uses the minimum of two values (and one shall exist in case of unilateral tolerance). Hope this answers your query.

Have a look at the following link which refers to the subject. http://forum.benchmarksixsigma.com/topic/696-six-sigma-for-hr-professionals/ Hope it helps. Best Regards, VK

It is about bringing improvements in OEE (Overall Equipment Effectiveness). Also referred as Kobetsu Kaizen, the objective is to bring down various losses. For bringing these improvements, various Lean Six Sigma techniques need to be utilized suitably.

You can go ahead for Black Belt directly with a longer time frame (10 days class sessions in addition to time spent with pre-course study material). This is similar to attending Green Belt followed by the upgrade Black Belt training.

Probably you have heard the story of three Romeos who did a few experiments to find out that the Juliet liked only one of them. (She used to wink from her balcony when this guy was present). Well, the other two Romeos vacated the flat. To continue with the fun, let us say this Juliet had another name - Cecelia What happened next is shown in the video below.

Here is good example for 80-20 rule. Here, it is even more lopsided. Apple owns 4% of the mobile phone market but controls a large share of the profit in the industry.

Certain tried and tested management concepts form the core thinking in lean six sigma. These differentiate LSS learning from others. A few of them are - Emphasis on data driven decision making Lean Six Sigma learning provides application oriented learning on decision methods that use data. The primary focus is to avoid gut feel decision making. Project by project approach to improvements. Team leaders learn how to engage others in improvement projects and ensure success. Focus on areas that affect customers and business most. Leadership involvement and customer orientation lead to the identification of powerful projects well supported within the company. While many other programs highlight “What to improve, Lean Six Sigma learning provides more comprehensive skill-set with a lot of learning on. How to bring improvements. Please feel free to discuss more on this subject here.

Lean Six Sigma learning can impact your future in several ways: Enhanced ability to make the right decisions - Professional and business success depends on this. Lean Six Sigma provides a set of world's best decision approaches that have proved there worth in a wide variety of settings. It pays to learn these techniques. Personal worth - People who are able to solve key problems systematically are the most sought people in an organizational setting. Engaging others - It is possible for you to facilitate action-based team learning if you gain this competence. Lean Six Sigma training is a kind of leadership training. Improvement expertise - You can succeed with process improvement initiatives (in any industry or function) if you begin with the right fundamentals and build up the blocks well over them. All the above result in career and business benefits. Please feel free to discuss this topic here.

Find out variables for which departure from randomness should trigger alarms. Primary objective of a control chart is to provide you signals that a process is out of control. Once you have a list of variables where special causes (assignable causes) need timely investigation, we can discuss more on this. Best Regards, VK

Great comments with relevant details, Lata. Cheers!

Some options are - cab utilisation efficiency = cab hours used/ cab hours available - COTA = cab on time arrival % - COTD = cab on time departure % You may decide on one pain area to start with and start collecting data for it. COTA or COTD shall need supporting data ( for each instance when failure occurs ). Once you have the data you can do Pareto analysis to find the critical X's. More views welcome. Best Regards, VK

Many techniques are relevant here. You may like to use QFD or Deign FMEA to identify focus areas for the next release. You may use hypothesis tests to see impact (or improvements after) of a release. You can use MSA to see if the data tracking methods provide you reliable data. You may use control tools to sustain improvements/ changes. Let me know if you have further specific questions.

Hi Prabhu, You may try this link - http://stattrek.com/lesson5/hypothesistesting.aspx

Response Optimizer - Provides optimum solution (Unique) but can provide output for given set of inputs (common) Contour Plot - Provides a single view that indicates expected outcomes at various combinations (unique), Does allow flagging and display of output for a given set of inputs (common) Response Optimizer - Can be used for optimizing more than one responses and shall provide the best solution at one click (unique) Contour plot - Can help highlight pockets of great responses at a glance (unique) Response Optimizer displays how close you are to the ideal solution with desirability measure. (unique) While Response optimizer allows to play around with more variables and types, Contour plot can be drawn only when you have at least two continuous X's and are willing to keep remaining variables constant. With Response Optimzer, you need to know what you want or expect, while with Contour plot, you can explore with an open mind.

If the causes are known and the solution is easy to find, the project does not classify as a Six Sigma project. If the project is all about listing average time taken in each task and reducing or eliminating non value adding time, you may take it as a Lean assignment.

In absence of trust, such projects seldom succeed. The expectations of each side should be made clear and agreed to at the beginning of the assignment.
