QbD and Digitalization’s need for Designing Quality into Solutions


“[They] lost their quality leadership to new, aggressive competition. The most obvious consequence was lost of market share (…) [due to] quality features that were perceived as better meeting customer needs [and] they did not fail in service as often.”

“Loss of market share is not the only reason behind [it] (…) a second major force has been the phenomenon of life behind the quality dikes. We have learned that living in a technological society puts us at the mercy of the continuing operation of the goods and services that make a society possible (…) without such quality we have failure of all sorts (…) at the least these failures involve annoyances and minor costs. At their worst they are terrifying.”

“A third major force has been the gathering awareness by companies that they have been enduring excessive costs due to chronic quality-related wastes (…) about a third of what we do consists of redoing work previously done (…) lacking expertise in the quality disciplines, they are amateurs in the best sense of that word.”

J.M. Juran’s assessment on Quality issues in the 1960s-70s.


 

What follows are some of the insights driving the work that I’m doing on reviewing, leveraging and updating QbD (Quality by Design) in the context of today’s fast growing and all-encompassing digitalization.

I am dusting off my research from 2010 on the 3Q Model. Back then I was a senior manager at Alcatel-Lucent’s Solutions & Technology Introduction Department. My current role is Senior Studio Director at Nokia Software’s Solutions Engineering. Note that the scope is End-to-End Solutions. These are holistic system-wide (cross-sectional and longitudinal) undertakings intersecting different domains to deliver the higher value of the whole. I have discussed QbD for Digital Transformation projects at the Design Thinking 2018 event and at the IEEE (Institute of Electrical and Electronics Engineers) conference on CQR (Communications Quality and Reliability) back in April and May of this year. Interestingly enough, both events were held in Austin, Texas.


Juran on QbD book.jpg

QbD was first coined by Juran, a renown pioneer of quality practices, whose work on that specific topic started in the mid 80s. He linked Quality to customer satisfaction and reliability as the two dimensions to focus on:

“Features” were defined as “quality characteristics,” which meant properties intended to satisfy specific customer needs. That would also include “promptness of delivery,” “ease of maintenance,” and “courtesy of service” to name some examples. “The better the features, the higher the quality in the eyes of customers.”

As far as reliability and, therefore, replicability and consistent performance, “freedom from deficiencies” conveyed the fact that “the fewer the deficiencies the better the quality in the eyes of customers.” A “deficiency” is a failure that triggers dissatisfaction, which calls for incurring higher costs to redo prior work.

“Fitness for use” was mentioned as an attempt to capture the above two together. The so-called Juran Trilogy entails Quality Planning, Quality Control, and Quality Improvement.


More than three decades have passed since Juran started to work on “New Steps for Planning Quality into Goods and Services.” Let’s decompose QbD’s acronym at face value and distill its essence.

As a designer, my belief & practice system focuses on “serial innovation” consistently delivering superior value. This is achieved by means of purposeful and elegant solutions equipped with capability models and optimal functionality leading to Quality Experiences.

Customer Delight, rather than just satisfaction, being the sought after outcome. This applies to both small and large undertakings, and as A. Kay, a pioneer in graphical user interfaces, best put it, “simple things should be simple, complex should be possible.”

Following that train of thought, “Designing Quality into Solutions” should become center stage to: (a) collaborative and iterative ideation, (b) agile development, (c) continuous delivery and (d) the dynamic diffusion of (e) new and mass-customizable digital services for consumer and enterprise markets, as well as no-for-profit. Overall, QoB is key to Operational Excellence.


Usability Testing Project


In a world where “Continuous Improvement” leads to incremental and breakthrough innovations, Quality’s critical KPI, Key Performance Indicator, can be expressed in terms of measurable advances in QoUX, the Quality of the Users’ Experiences. These are lagging (outcome) metrics that are far from static because they evolve within and over lifecycles. Therefore, reliability is not just applied to production operations, but also to the solution’s consistent performance and serviceability over time and under changing scenarios and events.


Given Quality’s unequivocal narrative around the “experiential” paradigm and, therefore, human-centric-optics, QbD’s best work should optimize for user “delight,” which is defined as superior “satisfaction,” rather than just aiming for requirements compliance.

It is very tempting to rally around core competencies within comfort zones that exist, and then settling on just aiming for “customer satisfaction” around “must-meet” baseline requirements. Though, that might not suffice given the necessity to innovate and better compete by leveraging unique sources of sustainable differentiation.


Let’s now state the obvious: “designing” Quality Experiences into digital solutions is best addressed by means of Human-Centered methodologies that optimize for (f) users’ “acceptance criteria” and (g) the kind of “adoption levels” that foster user base growth.

The opposite approach would risk the adverse effects (and hidden costs) that can be incurred when technical myopia leads the way. A. Cooper’s “The Inmates are Running the Asylum” captures that very well. His book is referenced below.

Just for the record, the year is 2018 and we are gearing for a pervasive digital world dominated by software defined systems. The 4th Industrial Revolution’s floodgates are set wide-open.

Low and high tech perform best when playing a supporting role. Technology enables “Services” which justify it, otherwise the so-called Chasm and Valley of Death wait around the corner. It pays to emphasize that “Services” are defined by “Use Cases.” So, it shouldn’t take much effort to see that “Use(case)ability” (“usability” being the proper term) is a CSF, Critical Success Factor. “Fitness for use” in other words.

Let’s take that further and couple “usability” with designing for usefulness,” “utility,” “consumability & serviceablity” as well as “affectivity” because perception and human affects orient satisfaction and dissatisfaction levels.

QbD cannot be put to work without adequately addressing Human Dynamics, which entails psychological (e.g. cognitive models, information architecture) physiological (e.g. device form factor, workstation ergonomics) and social dimensions (e.g. network effects increasing value for users.) That happens to be the SoW (Scope of Work) of HFE’s (Human Factors Engineering) interdisciplinary teams in Design Studios… and the topic of my next post on QbD’s Intellectual Capital.


 

A few more thoughts…

In spite of one’s day-to-day work and/or belief system being either closer to or removed from the kinds of jobs and tasks that make tech human, it makes sense to engage in meaningful outcome oriented and goal driven practices by applying HCD, Human-Centered-Design. The purpose is delivering quality and achieving customer acceptance and delight, given that customers are human beings. That is the reason why Design Thinking has outgrown the field of industry design and is applied to a wide variety of domains and disciplines nowadays.

Tech’s roller-coaster industry is packed with well intended technologies that fail. We all know that this is a fiercely competitive environment in constant change. Though, it is also true that, in many of those cases, UX, User Experience, professionals were not engaged at any part of the process, or were purposely involved at the back-end, or were called to come to the rescue in the eleventh hour. That leaves no room for Design to make a difference. Superficial changes just amount to bells-and-whistles and shiny-objects to disguise the underlying quality issues that are likely to re-surface at some point.

QbD’s top objective should be excelling at effectively & efficiently addressing our customers’ acceptance and adoption criteria. That remains true even in the context of full automation. Humans still get promoted and demoted (or fired) based on those system’s performance. D. Newman’s recent article on Forbes magazine rightly states that “you cannot run your business without people (…) you cannot operate technology without people (…) research have shown that people are a critical component for digital transformation.”

Today’s best practice calls for “reverse engineering” solutions by working from that human-centered understanding around Human Machine Systems (HMS.) That is substantially different from only relying on a far riskier “if you build it, they will come” model and its costlier brute-force mindset. 

When dealing with challenging, intractable and complex projects, overlooking that fact typically results in exponential project risk and plenty of the, otherwise, avoidable zig-zagging course corrections ahead (e.g. opportunity costs in financial analysis and hidden and latency costs in systems engineering.)

Agile’s iterative development and ability to pivot shouldn’t be a refuge for either subpar or no design effort, but a vehicle to best implement QbD and augment development capacity while minimizing technical debt. This is why this revision of QbD for today’s tech industry calls for Design Sprints to lead the way.

Last but not least, before dismissing this QbD revision as a philanthropic and humanistic only endeavor, I suggest deep thinking around its (1) business criticality and (2) contribution to risk mitigation.

Nokia LeanOps Digital Transformation – DX Videos

 


“The debate surrounding digitalization has gained increased practical importance […] changes in business approaches, opportunities for organizations in operational and business process development, with effect on the internal and external efficiency of IT.”

“When planning for digital transformation, organizations must factor the cultural changes they’ll confront as workers and organizational leaders adjust to adopting and relying on unfamiliar technologies.”

“Digital transformation has created unique marketplace challenges and opportunities, as organizations must contend with nimble competitors who take advantage of the low barrier to entry that technology provides.”

“Additionally, due to the high importance given today to technology and the widespread use of it, the implications of digitalization for revenues, profits and opportunities have a dramatic upside potential.”

Human Factors Engineering: leveraging the Internet of Things and Mobile Sensing Networks with Big Data and Social Analytics


“The ultimate test of a practical theory, of course, is whether or not it can be used to build working systems. It is good enough to use in the real world? […] Almost uniquely among the social sciences, this new social physics framework provides quantitative results at scales ranging from small groups, to companies, to cities, and even to entire societies […] it provides people –e.g., government and industry leaders, academics, and average citizens- a language that is better than the old vocabulary of markets and classes, capital and production […] the engine that drives social physics is big data: the newly ubiquitous digital data now available about all aspects of human life. Social physics functions by analyzing patterns of human experience and idea exchange.”Social Physics by Alex Pentland.

Back in 2010 I worked on the Amazing Learning Unit, a research project leading to a proof of concept demonstration. The anecdote behind it’s name was that by calling it A.L.U. we played with the fact that those same three letters formed Alcatel-Lucent’s stock ticker. On a more serious note, we partnered with Lego and the Illinois Math & Science Academy (IMSA) to unveil a simulation at Mobile World Congress in 2011, which was very well received.

The Amazing Learning Unit’s concept entailed “Lego robotics” equipped with Touchatag’s RFID readers and Android phones and tablets. As you can see in the above picture, these “mobile units” were designed to look, behave and roam around like autonomous screens, cameras and sensors with wheels.

Driven by human factors engineering principles, the thinking behind the project was centered not on technology, but on taking down the classroom’s physical walls, which can make today’s schools and school districts behave like “geofenced silos”. This is an environment that can constrain kids’ exposure to an outside world that’s growing more connected and diverse. The project’s main goal was to enable boundariless collaborative learning, our technologies being the means to that end.

The concept called for the robots to roam around the classroom and sense what a kid was playing with, or what book she/he was reading. Classroom’s objects and books would feature the Touchatag’s stickers to that end. The result is a mobile sensing network that falls in the IoT, Internet of Things, category.

Leveraging social analytics, we thought of a “serendipity engine” which would then connect the kid with another child from any other school who would be engaged in a similar activity, and whose skill and learning behaviors happened to be a good match for them to play together. The smartphone screens would prompt interactive online activities jointly with video calls engaging them in context-aware and “peer-to-peer collaborative learning”.

We discussed what’s now known as collaborative filtering and matchmaking options to promote role model behaviors and how to adequately display them to help realize everyone’s potential, and to do so in everyone’s best interest. We also looked into sensitive matters centered on behavioral analytics, privacy and the pros and cons of emotional and persuasive design features.

As part of the project’s research, gamification techniques were thought out to incentivize players, such as competitive challenges, progressive skill levels, in-game rewards and scoreboards. Circling back with a recent post on working with personas, the ones created for this project were modeled after our own children and my kid inspired and enjoyed participating in the project’s living lab.

The prototype unveiled at Mobile World Congress showcased some of the above concepts. It is worth sharing that the business goal was to help experience some as complex as the IP Multimedia Subsystem (IMS) in a new and radically light back in 2010. I strived to humanize what can otherwise come across as overlay technical and rather obscure sets of technologies behind network infrastructure, platforms and telecommunication services, the essence of our company’s product portfolio. Therefore, we purposely placed the emphasis on creating new experiences such as the one delivered by the Amazing Learning Unit. Our inventiveness and technologies became transparent and were in place to deliver the magic.

Interestingly enough, this research project led to discussions with MIT and a leading global network operator. That time around, we looked at how this kind of experiences can be applied in enterprise environments to raise productivity and foster collaborative and multi-disciplinary workstyles. Enabling new organizational and decision making cultures in other words. The following phase of the research was titled Immersive Mobile Systems, IMS in short : )
