SIX SIGMA
What is Six Sigma?
Six sigma is the structured application of tools and techniques applied on project basis to achieve sustained strategic results.

DMAIC six sigma approach
The six sigma approach for projects is DMAIC (define, measure, analyze, improve and control). These steps are the most common six sigma approach to project work. Some organizations omit the D in DMAIC because it is really management work. With the D dropped from DMAIC the Black Belt is charged with MAIC only in that six sigma approach. We believe define is too important be left out and sometimes management does not do an adequate job of defining a project. Our six sigma approach is the full DMAIC.

Define (DMAIC)
Define is the first step in our six sigma approach of DMAIC. DMAIC first asks leaders to define our core processes. It is important to define the selected project scope, expectations, resources and timelines. The definition step in the six sigma approach identifies specifically what is part of the project and what is not, and explains the scope of the project. Many times the first passes at process documentation are at a general level. Additional work is often required to adequately understand and correctly document the processes.

Measure (DMAIC)
Many think when they start a journey the most important thing to know is where they are going. While we agree knowing where you want to go is very important, we believe some of the first information you need before starting any journey is your current location. The six sigma approach asks the Black Belt project manager to quantify and benchmark the process using actual data. At a minimum consider the mean or average performance and some estimate of the dispersion or variation (maybe even calculate the standard deviation). Trends and cycles can also be very revealing. The two data points and extrapolate to infinity is not a six sigma approach. Process capabilities can be calculated once there is performance data.

Analyze (DMAIC)
Once the project is understood and the baseline performance documented and verified that there is real opportunity, it is time with the six sigma approach to do an analysis of the process. In this step, the six sigma approach applies statistical tools to validate root causes of problems. Any number of tools and tests can be used. The objective is to understand the process at a level sufficient to be able to formulate options for improvement. We should be able to compare the various options with each other to determine the most promising alternatives. As with many activities, balance must be achieved. Superficial analysis and understanding will lead to unproductive options being selected, forcing recycle through the process to make improvements. At the other extreme is the paralysis of analysis. Striking the appropriate balance is what makes the six sigma Black Belt highly valuable.

Improve (DMAIC)
During the improve step of the six sigma approach ideas and solutions are put to work. The six sigma Black Belt has discovered and validated all known root causes for the existing opportunity. The six sigma approach requires Black Belts to identify solutions. Few ideas or opportunities are so good that all are an instant success. As part of the six sigma approach there must be checks to assure that the desired results are being achieved. Some experiments and trials may be required in order to find the best solution. When making trials and experiments it is important that all project associates understand that these are trials and really are part of the six sigma approach.

Control (DMAIC)
Many people believe the best performance you can ever get from a process is at the very beginning. Over time there is expectancy that slowly things will get a little worse until finally it is time for another major effort towards improvement. Contrasted with this is the Kaizen approach that seeks to make everything incrementally better on a continuous basis. The sum of all these incremental improvements can be quite large. As part of the six sigma approach performance tracking mechanisms and measurements are in place to assure, at a minimum, that the gains made in the project are not lost over a period of time. As part of the control step we encourage sharing with others in the organization. With this the six sigma approach really starts to create phenomenal returns, ideas and projects in one part of the organization are translated in a very rapid fashion to implementation in another part of the organization.

Benefits of Six Sigma
There are numerous benefits of six sigma as a way to address issues and problems. Among the benefits of six sigma is the decrease in defects that are allowed to reach the customer. You can get some sense of the benefits of six sigma by reviewing some six sigma projects. Other benefits of six sigma include:
• Focus on customers.
• Improved customer loyalty.
• Reduced cycle time.
• Less waste.
• Data based decisions.
• Time management.
• Sustained gains and improvements.
• Systematic problem solving.
• Employee motivation.
• Data analysis before decision making.
• Faster to market.
• Team building.
• Improved customer relations.
• Assure strategic planning.
• Reductions of incidents.
• Measure value according to the customer.
• Better safety performance.
• Understanding of processes.
• Effective supply chain management.
• Design and redesign products/services.
• Knowledge of competition, competitors.
• Develop leadership skills.
• Breakdown barriers between departments and functions.
• Management training.
• Improve presentation skills.
• Integration of products, services and distribution.
• Use of standard operating procedures.
• Better decision making.
• Improving project management skills.
• Sustained improvements.
• Alignment with strategy vision, and values.
• Increased margins.
• Greater market share.
• Supervisor training.
• Lower costs to provide goods and services.
• Fewer customer complaints.

Maslow's hierarchy of needs


One of the many interesting things Maslow noticed while he worked with monkeys early in his career, was that some needs take precedence over others. For example, if you are hungry and thirsty, you will tend to try to take care of the thirst first. After all, you can do without food for weeks, but you can only do without water for a couple of days! Thirst is a “stronger” need than hunger. Likewise, if you are very very thirsty, but someone has put a choke hold on you and you can’t breath, which is more important? The need to breathe, of course. On the other hand, sex is less powerful than any of these. Let’s face it, you won’t die if you don’t get it!

Maslow took this idea and created his now famous hierarchy of needs. Beyond the details of air, water, food, and sex, he laid out five broader layers: the physiological needs, the needs for safety and security, the needs for love and belonging, the needs for esteem, and the need to actualize the self, in that order.

1. The physiological needs. These include the needs we have for oxygen, water, protein, salt, sugar, calcium, and other minerals and vitamins. They also include the need to maintain a pH balance (getting too acidic or base will kill you) and temperature (98.6 or near to it). Also, there’s the needs to be active, to rest, to sleep, to get rid of wastes (CO2, sweat, urine, and feces), to avoid pain, and to have sex. Quite a collection!
Maslow believed, and research supports him, that these are in fact individual needs, and that a lack of, say, vitamin C, will lead to a very specific hunger for things which have in the past provided that vitamin C -- e.g. orange juice. I guess the cravings that some pregnant women have, and the way in which babies eat the most foul tasting baby food, support the idea anecdotally.

2. The safety and security needs. When the physiological needs are largely taken care of, this second layer of needs comes into play. You will become increasingly interested in finding safe circumstances, stability, protection. You might develop a need for structure, for order, some limits.
Looking at it negatively, you become concerned, not with needs like hunger and thirst, but with your fears and anxieties. In the ordinary American adult, this set of needs manifest themselves in the form of our urges to have a home in a safe neighborhood, a little job security and a nest egg, a good retirement plan and a bit of insurance, and so on.

3. The love and belonging needs. When physiological needs and safety needs are, by and large, taken care of, a third layer starts to show up. You begin to feel the need for friends, a sweetheart, children, affectionate relationships in general, even a sense of community. Looked at negatively, you become increasing susceptible to loneliness and social anxieties.
In our day-to-day life, we exhibit these needs in our desires to marry, have a family, be a part of a community, a member of a church, a brother in the fraternity, a part of a gang or a bowling club. It is also a part of what we look for in a career.

4. The esteem needs. Next, we begin to look for a little self-esteem. Maslow noted two versions of esteem needs, a lower one and a higher one. The lower one is the need for the respect of others, the need for status, fame, glory, recognition, attention, reputation, appreciation, dignity, even dominance. The higher form involves the need for self-respect, including such feelings as confidence, competence, achievement, mastery, independence, and freedom. Note that this is the “higher” form because, unlike the respect of others, once you have self-respect, it’s a lot harder to lose!

The negative version of these needs is low self-esteem and inferiority complexes. Maslow felt that Adler was really onto something when he proposed that these were at the roots of many, if not most, of our psychological problems. In modern countries, most of us have what we need in regard to our physiological and safety needs. We, more often than not, have quite a bit of love and belonging, too. It’s a little respect that often seems so very hard to get!
