Six Sigma


I came across an interesting question at the Customer Management IQ site today that should be of interest to any executive or manager responsible for voice of the customer at their organization. The questioner wanted to know how to leverage her VOC, and whether some customer opinions are more imortant than others. Here’s my $.02:

Her question really has several facets: (1) what type of VOC will be most leverageable? (2) How should that VOC be analyzed? (3) Which customers are most important?, and (4) How do you actually leverage that information? I’ll address those issues in that order.

(1) As you know, there are many types of VOC, ranging from the passive and reactive (complaints) to the more proactive but qualitative (interviews, focus groups) to the proactive and quantitative (surveys and panels). Each serves a purpose, but to truly leverage your VOC it should be proactive, purposive, and quantitative. Moreover, if you really want to leverage your customer information, you should extend VOC to become the Voice of the Market (VOM) – which means that you would be surveying not only your own customers but those of key competitors as well.

(2) Your next task will be to transform that survey data into meaningful metrics. By meaningful, I mean that the resulting metrics should (a) be predictive of future business performance, and (b) provide managerial direction. This will require a shift from the metrics of customer satisfaction to the metrics of customer value. There is now lots of evidence (Gale, Reidenbach, Reichheld, and others) that the metrics of customer satisfaction do not correlate well with business performance. Why would you rely upon a metric that is unrelated to your business goals? The metrics of customer value, on the other hand, have proven to be the best leading indicators of market share – leading to both high levels of customer acquisition and customer retention (loyalty).

(3) Now we get to the crux of the matter: the metrics of customer value are both product- and market-specific. People buying a luxury sedan will define value differently from people looking for a sports car. And the business user of a computer will define value differently than will the typical home user. You want to focus your investment in value metrics on those market segments that are most attractive for your business (they’ll provide the greatest ROI) – and you want to use those metrics to understand value within those segments better than anyone else against whom you are competing. There are some great tools available that will help you identify those high-priority segments.

(4) Finally, you want to be able to truly leverage your value metrics into superior business performance. Those value metrics should enable you to identify competitive performance gaps on those factors that are critical to quality from a market perspective (CTQs, in Six Sigma parlance). The nature of those gaps, whether positive or negative, will point you to the specific product (service), people, or process issues that you can improve to achieve or sustain a competitive advantage. You’ll find some great information on the “how to” in one of our most recent books, “Competing for Customers and Winning with Value.”

Several writers have commented on Six Sigma Marketing. The major thrust of these comments is focused on how to apply Six Sigma to Marketing. And, while making Marketing and Marketing activities more efficient, Six Sigma Marketing must focus on making Marketing more effective – actually acheiving sales and market share objectives.

Six Sigma Marketing is all about integrating the disciplined, data driven principles of Six Sigma with Marketing’s focus on revenue growth and market share. This integration has as its core the idea of value – creating and delivering the highest quality at the best price. Value has been shown to be the best leading indicator of sales and market share growth.

Six Sigma Marketing accordingly, requires a new set of tools not resident in either Six Sigma or Marketing. In other words, applying the tools of Six Sigma to Marketing will not do the job. You can’t pound a nail with a screwdriver. You have to learn how to use a hammer.

Six Sigma Marketing requires the jettisoning of much of the conventional wisdom surrounding both Six Sigma and Marketing. Chief among the ideas that have to change is the reliance on customer satisfaction as the principle metric. Satisfaction has little, if any, linkage to changes in sales and market share. Consequently it makes little sense to rely upon customer satisfaction as the strategic goal since it does not impact either sales or market share. Customer value does.

Market Value Solutions has been practicing Six Sigma Marketing for about ten years and experiencing significant successes. The tools of Six Sigma Marketing are powerful and provide a clear guidance for growing sales and share. No longer does Marketing have to be agenda driven or based on company lore. Six Sigma Marketing is driven by the voice of the market (VOM) and not the VOC (voice of the customer).

In subsequent blogs I will be discussing several other points of departure between Six Sigma Marketing and Six Sigma and Marketing as it is currently practiced.

“The time has come,” the Black Belt said,
“To talk of many things:
Of Markets, and value and quality
OF Six Sigma Marketing,
Why we are short of projects
And, how to move away from simple cost cutting.”

“But wait a bit” the CEO cried,
“Our market share is low
With poor quality and poor value
How are we to make our sales grow?”
“No worries” said the Black Belt
Six Sigma Marketing is clearly the way to go!”

“The Voice of the Market,” the Black Belt said
“Is what we chiefly need-
Value and value tools besides
Are very handy indeed…
Now if you’re ready, O Six Sigma team
Let us plant, grow and nurture the SSM seed.”

“But lose the VOC?” the team cried
Turning a little blue,
“After such a long dependence, that would be
A very radical thing to do.”
“The path is clear,” the Black Belt said
For now, more than ever, we need the market view!”

“But what of DMAIC?” all the lesser belts did cry,
“Or the 4Ps?” the diffident marketers whined.
“No sweat” said the Black Belt
“Six Sigma and Marketing are now aligned.
It’s time for us to change,
For Six Sigma Marketing – this is the exactly time.”

Six Sigma Marketing” the Black Belt said
“Is what we need to do.
Forget the cost cutting
Instead, let’s concentrate on revenue.
It’s time to think externally
And how we can create and deliver superior value.”

“O defect reduction”, the Black Belt intoned,
“You’ve had a pleasant run.
Let’s turn our face to market share
And start to count the mun!
With Six Sigma Marketing our success is guaranteed
Our superior value will put all of our competitors quickly on the run.”

How many Six Sigma practitioners have been successful in migrating Six Sigma practices to marketing? Why have Six Sigma writers so often thought about the two “disciplines” as water and oil, art and science, fire and water and all of those other comparisons that express an incompatability? What are the success factors in merging the two? What will doom the integration? I am not talking about making marketing activities less expensive or making Six Sigma more “customer friendly”, but rather a full scale integration to create a new type of marketing and an extension of Six Sigma.

I know there is growing interest in this topic and would like to use an “open source” approach for discussing it. Let’s start a conversation regarding Six Sigma and Marketing and begin to explore some of these issues. As a start, you might want to read a couple of whitepapers that I have come across:

The Quest for Quality: Applying Six Sigma Principles to Marketing
The Power of Six Sigma and Marketing: Increased Marketing Effectiveness

Both of these whitepapers are free at www.Tocquigny.com.

Several days ago, an anonymous reader posted a pretty basic, but important question on the iSixSigma forum and was seeking assistance.  Basically, the reader was seeking to create an actionable survey instrument, was wondering about the utilty of an “importance-satisfaction” approach, and was looking for additional information on scaling and analyses.  Several readers provided helpful advice, with one especially helpful response from George Chynoweth. That said, most of those who responded seemed to overlook 4 critical questions underlying the original question:

1.  Are the metrics of customer satisfaction the right ones to be using for actionable results?

2.  What are the benefits/drawbacks to the importance/performance paradigm?

3.  What’s the best source of questions for a survey?

4.  What types of analyses will produce the most actionable results? (relates back to issue #1)

The answers to these questions are so critical to the original question that I include my responses here.

1.  The metrics of customer satisfaction have repeatedly been shown to lack a substantive connection to business results (see Reichheld.  See also Reidenbach.)  People make purchase decisions – whether buying pizza, cars, insurance, or tractors – based upon their perceptions of the value received.  And perceived value is a function of perceived quality relative to perceived price.  This interaction of quality and price (plus image) is simply not addressesed with the metrics of satisfaction.  For that, you need the metrics of value.

2.  There are several problems with the importance/performance paradigm.  One of those was addressed in the original iSixSigm thread,, namely, the issue of respondent fatigue and attrition.  Another has to do with the distinction between qualifiers and determiners.  Qualifiers are “table stakes: typically very important, but typically not a source of differentiation.  Airline safety would be a good example: very important, but probably not worth investing for differentiation.

3.  I applaud the suggestion by QualityColorado to couple surveys with focus groups, but would differ on the timing.  Focus groups (and/or customer interviews) should be the source of your survey questions.  For more information on designing good questionnaires based on value, I’d recommend the ASQ publication, Strategic Six Sigma for Champions: Keys to Sustainable Competitive Advantage, especially chapters 4 – 6.

4.  Finally, the anonymous questionner was correct in assuming that one of the primary analytical tools will be regression-based.  But, for a market-focused definition of CTQs, you’ll need to precede your regression analyses with factor analyses.  Then you’ll need to identify specific competitive value performance gaps – whether positive or negative – because these gaps will serve as the starting point in identifying and prioritizing Six Sigma projects.  Chapters 1 – 3 of Strategic Six Sigma for Champions will explain just how that works

If you’d like more information regarding the issues you’ve raised, or have additional questions, you can contact me offline.  Providing your organization with the type of information that can drive both competitive strategy and significant process improvements will make your services invaluable.  

I get so sick and tired of hearing clients refer to coworkers as “customers”. It usually arises when talking about process improvements. Typically the client says he or she needs to understand how their “customers” define value so that they can change their processes to provide greater value. The “customer” is the coworker that is on the receiving end of the process – not the end user who buys the product or service. This coworker is not the “customer” nor is he or she the “internal customer”.

Splitting hairs? Not really. The idea that there are “internal customers” leads to a seductive attitude that drives much process improvement. The so-called “internal customer” is easy to talk to, understand, lives in a highly controlled environment, is less costly to access and, in short, represents an easy target. It is a concept that has evolved making it easier for lean and six sigma gurus to extoll the need for the voice of the customer (VOC) in driving process improvements. Instead of surveying, or conducting focus groups with real customers, it is now possible to redesign processes and value streams in response to the needs of “internal customers”. The CTQs associated with internal custmers are likely to be significantly different from the CTQs of real customers. Do the resultant improvements actually help the organization’s competitive value proposition or do they simply make another employee’s work easier, reduce the number of employees, or cut costs? Over time people are deluded into thinking that they are using the VOC to drive process improvements when they are actually ignoring it. The organization eventually institutionalizes the wrong notions regarding customers and becomes even more internally focused than ever.

If there is no line of sight between the internal process and the end user, be careful. It is entirely possible that process changes do not improve the organization’s competitive value proposition and may, in fact, do harm to it.

Virtually all Six Sigma gurus opine regarding the importance of the voice of the customer (VOC). Many organizations, however, simply pay lip service to customer needs. Most of the information that drives their Six Sigma deployments is internally generated either from “reliable sources” or more likely “myths” and customer “lore”. Here are a couple of points that you might want to consider if you are serious about using the VOC to drive your Six Sigma initiatives.

• First, there is typically more than one VOC. Most organizations serve more than one group of customers. Breaking these customers down into more homogeneous groups (markets or market segments) has a major benefit. The clarity of their wants and needs is crisper, more understandable, and more actionable. By focusing on markets or segments you eliminate one of the sources of measurement variance – between group variance – and deal only with within group variance – the two sources that make up total variance. This makes your measurement of customer CTQS (critical-to-quality factirs) more focused because the standard error of the mean (a measure of variability) is likely to be smaller. You have eliminated a portion of the noise that can confound interpretation. Second, the VOC is dependent not only on segments but also the products or services that these segments use. Men buying sports cars will have different needs than women buying minivans. The criteria they use to evaluate the different autos will vary significantly. Failure to capture the VOC at this level of granularity can lead to wrong conclusions and greatly warp your analyses.
• Second, if you are seeking to use Six Sigma as a tool to improve your market performance (increase top line revenues or market share) you will need to listen not to the VOC but to the VOM (voice of the market). Market share is won or lost based on the competitive dynamics of the marketplace, not solely the whims of your own customers. Customers are won either as new entrants to the market or as acquired customers who have chosen your product or service because of your superior value proposition. Consider what happened to Cadillac and AT&T during the 1980s. Both organizations were enjoying strong customer satisfaction scores among their own customers but were losing market share to their competition. What was happening was that these organizations were focusing on the VOC and not the VOM. Had they been focusing on the latter they would have understood that their competition was providing superior value and that they were losing customers to these competitors. Focusing only on the VOC can produce misleading guidance.
• Third, some product/markets (markets/segments that use specific products or services) are worth more to your organization than others. It is not uncommon to find organizations investing in product/markets that are actually unprofitable. Your Six Sigma initiatives are one such investment. Prioritizing product/markets based on such criteria as:
o Margins
o Competitive intensity
o Market share
o Market growth rates
o Synergies with other product/service offerings
insures that your organization is not wasting its resources investing in “dry holes”. Picking those product/markets that are most important to your future economic growth insures that your Six Sigma initiatives are congruent with your overall growth strategies. These are the VOMs that you will want to listen to.

A couple of questions: Does your organization have an effective market segmentation schema and do you prioritize your product/markets based on economic opportunity?

One of the more frequently asked questions that I encounter has to do with the periodicity of measuring the voice of the customer (VOC). To get a handle on this, the first thing you need to do is to distinguish between the strategic use of VOC and its tactical use. When the intent is to use VOC strategically (e.g., for the identification of Six Sigma projects that will maximize performance on CTQs), then the appropriate interval will depend upon just how dynamic your industry is. If you are operating within a very dynamic industry (e.g., software, wireless telecom) you may want to do VOC as frequently as every three to four months. If yours is a rather mature industry (e.g., the manufacture of agricultural equipment), then you need to conduct VOC surveys only annually, or even less frequently. Keep in mind, however, that the strategic use of VOC requires measuring more than the perceptions of just your own customers. You really need to measure perceptions of your customers and those of your competitors. The point is to identify competitive gaps in your performance relative to key competitors, and then identify Six Sigma projects that will either leverage positive gaps or close negative gaps. This is the only way to use Six Sigma strategically — for the purpose of increasing market share and revenue. If you don’t begin with strategic measures of VOC, your Six Sigma projects will likely be limited to cost cutting exercises. For a good article on the strategic use of VOC, see the Sept issue of Quality Progress Magazine: Market-Focused, Value-Driven: It’s All About Gaps.
As for the tactical use of VOC, here’s where you want to measure your own customer reactions to improvements that you’ve made – whether those are product, people, or process improvements. Those improvements will serve no strategic purpose unless they are actually seen, felt, or observed during the customer experience. That means that you should be measuring the perceptions of your own customers on an ongoing transactional basis. Identify those transactions that are being impacted by your value stream improvements, and measure a sample of those on a daily or weekly basis. This can be done very inexpensively when conducted by your own call center personnel, using a web-based, menu-driven “CATI” system. Essentially, you’ll be using call center time that’s likely already available to make outbound calls conducting a very short survey that then automatically updates your database, providing real-time reporting for your entire management team.
To summarize: When conducting VOC for the strategic purpose of identifying Six Sigma projects that will increase revenue and market share, do this on a very limited basis, but use the data to identify competitive performance gaps. When using VOC data for the tactical purpose of monitoring customer reactions to your improvements measure frequently and track progress.

Just two questions: Are you measuring the voice of the customer and how do you do it?

The conventional wisdom says that a satisfied customer is a profitable customer. Reality, as is often the case, denies the conventional wisdom. Here is some unconventional wisdom about satisfaction.

• Satisfaction is a lagging indicator. It is a reactive response to an experience.
• It is synonymous with happy. A satisfied customer is a happy customer. This is an emotion.
• Satisfaction typically focuses only on the organization’s customers and ignores the competitive dynamic that drives changes in market share and top line revenues.
• Satisfaction ignores the interaction of price and quality. It is this interaction that makers value the powerful concept that it is.

All of the above reasons explain why satisfaction has little, if any, linkage to changes in market share. This is why:

• during the 1980s AT&T was losing market share while experiencing some the highest satisfaction scores in their history.
• during the same period, Cadillac was losing market share among its most satisfied customers.
• one of our clients was churning 50% of its satisfied customer base.

Moreover, Fredrick Reichheld, writing in the Harvard Business Review (2003) about the lack of linkage between satisfaction and performance states:

Indeed, in some cases, there is an inverse relationship; at Kmart, for example, a significant increase in the company’s ACSI rating was accompanied by a sharp decrease in sales as it slide into bankruptcy…Our research indicates that satisfaction lacks a consistently demonstrable connection to actual customer behavior and growth. This finding is borne out by the short shrift that investors give to such reports as the American Consumer Satisfaction Index. The ACSI, published quarterly in the Wall Street Journal, reflects the customer satisfaction ratings of some 200 U.S. companies. In general, it is difficult to discern a strong correlation between high customer satisfaction scores and outstanding sales growth. (p. 4)

This lack of linkage makes it even more perplexing why many Six Sigma writers and practitioners hang their hats on customer satisfaction as an objective especially when the stated target is increased value. If value is the objective, then value should be measured, not satisfaction!

Two questions: How many are still using customer satisfaction as a strategic metric and how successful have you been in linking it to market performance (top line revenues, market share or profitability?
