An Apple a day — Use QFD to systematize Steve Jobs' design genius beyond a single individual

(image - An Apple a day keeps competitors away)
In my opinion, late Steve Jobs was a rare individual who had such an intuitive grasp of the fundamentals of QFD thinking. For example, in the April 1, 1989 interview with Inc. Magazine, he was asked by reporters Bo Burlingham and George Gendron, "Where do great products come from?"

This is what Jobs said:

"I think really great products come from melding two points of view-the technology point of view and the customer point of view. You need both.

"You can't just ask customers what they want and then try to give that to them. By the time you get it built, they'll want something new. It took us three years to build the NeXT computer. If we'd given customers what they said they wanted, we'd have built a computer they'd have been happy with a year after we spoke to them-not something they'd want now..."

Let me put this in QFD perspective.

We see two common flows in the way QFD is practiced: forward and reverse. Forward QFD begins with the voice of the customer which is often a mixture of "what they want," that is product performance, features, and technology. Because customers rarely know what the future may bring, their voice is typically tied to the past or present.

As Jobs points out, the product may be sufficient for the past, but insufficient at the time of launch or during its useful life. You can ask customers what they want as a starting point of a QFD analysis. The tool for this analysis is the Customer Voice table; its purpose is to translate voice of customer (VOC) into true customer needs. In this table, we explore with customers why they want something.

For example, a customer in a café may state "I need a hot cup of coffee," but what they really need is "I am cold and I want to warm up." Using Jobs logic, you could produce a cup of coffee that was too hot to drink, thus forcing the customer to wait until it cooled down. You would give them what they asked (hot), but not really meet their needs (warm up).

In modern QFD, we define a customer need as being product-independent, and that is the first step in creating great product.  Read More ...

Towards QFD-based Industrial Design

(image - QFD and Industrial Design)This paper reports how to improve web-based Learning Management Systems (LMS) through integration of the elements of Service Oriented Architecture (SOA) and Quality Function Deployment (QFD). Customer Orientation is achieved within QFD by a systematic approach. Within industrial design, requirements of the customer are also analyzed and deployed with the power of artistic creativity and less with a systematic or qualitative approach. This paper proposes an integration of QFD and industrial design to take advantage of the strength from each method. The presentation will include a case study and a framework for QFD-based Industrial Design.

QFD for activating a workplace Ba—Part 2


(image - workplace)The various components of QFD draw out member's tacit knowledge through "Ba" (the workplace gemba). In order to achieve this, the "Ba" must be invigorated with changes that encourage the individuals to express and share his/her tacit knowledge. This presentation, a sequel to the author's 2012 presentation, will examine the relationship between QFD and "Ba" from the viewpoint of cognitive engineering and social-psychology, including some examples from the author's company practice.

A Critical Analysis of the Turkish Literature on QFD


(image - state of QFD in Turkish region)This study, based on the published resources produced between 2000 and 2012, provides a holistic picture on the current state of QFD in the Turkish region, both in private industry sectors and academic research field.
Specifically, it identifies the levels of awareness and prevalence of QFD methodology in the region, the purpose for the usage, implementation levels, difficulties, and overall analysis. With economic activities rapidly globalizing and competitive pressure mounting, this knowledge can be the competitive differentiators for the developing nations such as Turkey as they will compete more on the global stage. It also offers academic researchers a solid comprehensive reference on the state of QFD applications and studies in this economically growing region.

QFD and Requirements Prioritization: A Survey on Security Requirements for Cloud Computing

(image - Clound Computing security)Prioritization is an essential task within QFD, and QFD is highly suitable for the development of Cloud Computing (CC) applications where non-functional requirements play a main role. Many of them are security requirements, often the main concern for CC investments. This paper introduces the usage of QFD for Cloud Computing (CC). In this research, CC security requirements were prioritized by pairwise comparison, showing that not all security requirements are equally important. With this finding, the appropriate usage of QFD for CC development will be discussed.

A Statistical Engineering Approach to Codifying the Voice of the Customer

(image - HOQ whats and hows)Virtually all design projects involve the collection/processing of the Voice of the Customer to develop a set of requirements to which the producer designs their process/product.Approaches to efficiently and effectively deriving those requirements involve multiple techniques from the fields of market research, quality engineering, design engineering, and inferential statistics. This paper proposes a way to create a logical flow for the Voice of the Customer processing by codifying a series of tools into a linear statistical engineering road-map, and thereby more efficiently populating the House of Quality matrix that uses the "whats" (functions) and "hows" (functional requirements) approach. The exposition is supplemented with a lucid hypothetical example.

Study of Applying QFD to Modularity Strategy

(image - Modularity design)
Japanese manufactures are excellent at developing integral type products, such as cars and complicated machines that need fine tuning (e.g. semiconductor manufacturing machines). However, many products are currently shifting toward modular systems which require better architectures and modularity logic and rules. This presentation will show how to better define modular product architectures through the analytic structure of QFD, specifically how to arrange many complex issues such as customer needs, cost, technology, manufacturing feasibility, serviceability and so forth in a series of matrices so that modularity can be better simulated.

Can ordinal scale numbers kill you?

This May 19, 2013 article in USA Today might make you nervous. According to a study of 1400 sunscreen products by the Environmental Working Group, many continue to carry SPF ratings that some experts consider misleading and potentially dangerous. The reason, the article states is that:

(photo of sunscreens, source FDA)"SPF numbers like 100 or 150 can give users a false sense of security, leading them to stay in the sun long after the lotion has stopped protecting their skin. Many consumers assume that SPF 100 is twice as effective as SPF 50, but dermatologists say the difference between the two is actually negligible. 

"Where an SPF 50 product might protect against 97% of sunburn-­causing rays, an SPF 100 product might block 98.5% of those rays. There is a popular misconception that the SPF figure relates to a certain number of hours spent in the sun. However this is incorrect, since the level of exposure varies by geography, time of day and skin complexion."

In other words, people believe (as did I until I read this), that SPF numbers were ratio scale and that 100 provided twice the protection of 50. In fact, as this article postulates, they are ordinal and SPF 100 is only 1.5% more protection than SPF 50.

This is the problem with ordinal scales. They confuse people into interpreting numbers the wrong way.

QFD experts have known this problem for many years, and in our early days (1966-1985), we didn't have an easy solution to obtaining ratio scale values from subjective judgments. In the House of Quality (HoQ), rating customer needs or competitive performance on a 1-5 ordinal scale, or enumerating relationship weights using 1,3,5 or 1,3,9 ordinal numbers are examples of ordinal scale subjective judgments. Like SPF, you cannot meaningfully add, subtract, multiply, or divide them.

The solution to the problem came to us QFD folks in 1986 when Dr. Saaty's Analytic Hierarchy Process (AHP) became available as a PC program, allowing us to accurately convert subjective judgments into ratio scale values. It took me a few projects to see the difference in accuracy. For example, a judgment of "4" on the ordinal scale is usually perceived to be two times a judgment of "2."  But if you convert the 1-5 to ratio using AHP, it turns out that the judgment of " 4" is 26.0% and "2" is 6.8%.  26/6.8= 3.82 meaning that the judgment of a "4" is almost four times the judgment of a "2." Imagine the impact this mistake could have on a multi-million dollar project!

So, if you are not using AHP to calculate ratio scale judgments in your QFD, switch now, before the summer sun kills you.

Delivering crystal-clear brand identity from end-to-end

"Drunk With Power," an October 14, 2012 New York Times article by Daniel Duane, describes an on-line wine seller named Jon Rimmerman Jon, who earned  his retail cred while at Starbucks. Jon summarizes it as this:

photo of wine
 “the beauty of retail marketing … can be roughly translated as defining a crystal-clear brand identity and then ensuring that everything from the product to customer relations reinforces it."

I like his words, and would like to give them a QFD flavor.

The purpose of modern Blitz QFD® is to define and prioritize with crystal clarity, that which is most important to the customer, and then ensure that everything from the product to customer relations reinforces it.

Let me explain.

"Crystal clarity" of what matters most to customers. In QFD, this means having a customer need that truly states the value proposition to the customer. Typically, this is the benefit a customer receives from having a problem solved, an opportunity enabled, or image enhanced. It should be independent of the product, its features, and its technology. A Voice of Customer (VOC) statement such as "fits in my pocket" is not a customer need, but rather a fuzzy set of dimensions.

With the Customer Voice table, a Blitz QFD® tool, you can translate that into true customer needs such as "I can carry with me easily," "Easy to store in my pocket," "Easy to retrieve from my pocket," "Stays in my pocket when I move around," "Does not damage my pocket,"  etc. This helps us understand these true benefits and avoid later design mistakes resulting in "the product falling on floor when I lean over," "the product tearing my pocket off," "the product is too hard to remove from my pocket when I want to get it out quickly," etc.

Crystal clarity means the need statement must be at a sufficient level of detail to be actionable in design, which is typically a tertiary level on a customer needs hierarchy. Abstract expressions such as "convenient" should be deployed to more detail.

Crystal clarity also means that we have accurate priority values. The QFD community replaced the 1960s' ordinal scale weights with AHP-derived ratio scale weights in the mid-1980s, first in Japan and then later in the US. Unfortunately, most English language QFD books and articles were written before this and missed the update. Even today, new QFD texts still cite these early works, and continue the math errors resulting from using ordinal weights in both customer needs and matrix relationships, as well as misuse of matrices including using a House of Quality matrix (HOQ) when it is not needed.

click to go to International QFD Green Belt® Certificate Course
This is why the QFD Institute Green Belt® and Black Belt® courses are strongly recommended for professionals in product/service/business development, marketing, design, sigma/lean/DMAIC black belts and so forth. You will learn how to use the modern AHP approach and we provide updated Excel templates. Without AHP clarity, your limited resources risk missing what is truly important and deploying lower priority things.

"Ensuring that everything from product to customer relations reinforces it" is the QFD call for end-to-end quality assurance. Depending on your industry, product, and company, this will vary, but typically describes, end-to-end, the full development, commercialization, and retirement of the product, service, or software. In other words, we must assure that any weakness related to the most important customer needs are made robust. For example, if poor packaging compromises the sterility of a medical supply item, it becomes scrap (let's hope!), wastes money, ruins reputations, could result in injury or death, etc., no matter how well the function and performance of the item was designed.

In classical QFD, each of the design, develop, test, procure, produce, assemble, package, ship, store, sell, support, and other commercialization dimensions has its own matrix. Since the matrix only compares two dimensions at at time, anywhere from four to thirty matrices have been identified in the literature. Maybe in the 1960s-80s, we had enough time and people to analyze these, but that is difficult these days.

In Blitz QFD®, all these matrices have been replaced for the most part by a single Maximum Value table. One tool goes end-to-end through all the dimensions. How do we do it – with crystal clarity focus on what matters most to customers. This is where we apply our best efforts, first. Makes sense, doesn't it? The Maximum Value table is one of the key tools taught in the QFD Green Belt® Course and QFD Black Belt® Course.

Additional training dates will be published at QFD Training & Events Calendar as they become confirmed. Or you can e-mail to us.

Laundry detergent pods mistaken for toys as well as candy

In a recent blog "Design for Safety? The dirty laundry of NPD!", I wrote how dangerous the new laundry detergent pods are for small children because they look like colorful jelly candy and are packaged in clear "candy jar" container that is a magnet for a child's attention.

I thought the problem was limited to children ingesting them, but now there are more safety modes to consider.

image - pods detergentIn a new story on this news video, it seems that just squeezing the pouches like a balloon can cause them to spray out on the child's face and eyes. The pouch's outer skin is thin for easy dissolving in water, and the concentrated chemicals (one small pouch replaces a cup of standard detergent) are so caustic that they can immediately begin burning the lining of the eyes.

While the manufacturers are busy describing the cautionary language on the packaging (which pre-school toddlers can't read), parents are having to choose between laundry convenience and their children's eyesight.

For those of us concerned with product and packaging design, I again urge a safety mode and effects analysis akin to FMEA ((Failure Modes and Effects Analysis). Sure, we can blame the customer, but that does not build business and trusting relationships. As companies go global with their products, we have to consider the context not only of our familiar homes, but the different use modes and environments of the global customers to whom we wish to sell.


PS: You may also need a better RPN calculation when designing for a black swan event. See "How To Handle VOC Issues — Lessons from Japan crisis: Anticipating Improbables with Irreversible Consequences"

Design for Safety? The dirty laundry of NPD!

I don't get to the supermarket as often as I should. But when I do, my eyes cast around for lost opportunities for product improvement.

On a recent shopping trip, I happened by the laundry detergent shelf and my eyes were drawn to a large, clear plastic container that contained small, 3/4" diameter colorful balls of laundry detergent.

You drop these detergent balls into the washing machine according to the amount of clothes and without the trouble of accurate measure or the mess of spilled powder. The container design was such that anybody could easily open it with one hand, which I guess is handy if you have the other arm full of dirty clothes.

What struck me immediately was that these colorful balls looked like candy in a candy jar that any child could open, and then put in their mouth.
image - a clear plastic jar of candy gums

How could a company that caters to families and household cleaning products (and also some snack foods), design something with such potential risks of a child eating laundry soap thinking it was a cookie? Certainly, this must have been thoroughly tested.

A quick Internet search on the smart phone told otherwise. Just three weeks earlier, in fact, a news report indicated that across the U.S., as many as 10 emergency calls were being made to the Poison Control Center each day regarding this product. Small children were "vomiting, wheezing and gasping" within minutes of biting into the detergent balls.

The manufacturer's response was  “We encourage consumers to keep the products out of the reach of children as with any household chemical.”

So what's the QFD connection?

Just like reliability, safety is a critical design element. Danger Mode and Effects Analysis should be a part of Safety Deployment in your QFD analyses. For users of Modern QFD, this means there should be a section in the Maximum Value table that addresses product and package safety concerns associated with critical customer needs.

For users of Classical QFD matrices, this means a Safety Deployment consisting of one or more matrices to identify and prioritize potential danger modes for additional study.
