The fourth industrial revolution is characterized by intelligence: smart, hyperconnected agents deployed in environments where humans and machines cooperate to achieved shared goals — and using data to generate value.
Want to find out what Quality 4.0 really is — and start realizing the benefits for your organization? Check out this month’s issue of ASQ’s Quality Progress, where my new article (“Let’s Get Digital“) does just that. Quality 4.0 — which we’re working to bring to the practice of quality management and quality engineering at Intelex — asks how we can leverage connected, intelligent, automated (C-I-A) technologies to increase efficiency, effectiveness, and satisfaction: “As connected, intelligent and automated systems are more widely adopted, we can once again expect a renaissance in quality tools and methods. The progression can be summarized through four themes:
Quality as inspection: In the early days, quality assurance relied on inspecting bad quality out of the total items produced. Walter A. Shewhart’s methods for statistical process control helped operators determine whether variation was due to random or special causes.
Quality as design: Inspired by W. Edwards Deming’s recommendation to cease dependence on inspection, more holistic methods emerged for designing quality into processes to prevent quality problems before they occurred.
Quality as empowerment: TQM and Six Sigma advocate a holistic approach to quality, making it everyone’s responsibility and empowering individuals to contribute to continuous improvement.
Quality as discovery: In an adaptive, intelligent environment, quality depends on how quickly we can discover and aggregate new data sources, how effectively we can discover root causes and how well we can discover new insights about ourselves, our products and our organizations.”
This article originally appeared on the Intelex Community on 9/14/2018 at https://community.intelex.com/explore/posts/why-fema-monitoring-waffle-house-weekendSometimes the most informative metrics show up in the strangest of places.Case in point: with a hurricane making landfall today in North Carolina, and the prospect for catastrophic flooding over the weekend and into next week, emergency managers are mobilizing for action – and if you’re in the path of the storm, you may be doing the same. Have you started monitoring the Waffle House Index? The US Federal Emergency Management Agency (FEMA) has.Originally devised by W. Craig Fugate, former FEMA Director, the Waffle House Index is based on the observation that the popular 24-hour breakfast chain has historically been unusually well prepared for disasters. Part of their business model is to be the spot for emergency personnel to rely on for their coffee and nourishment – a valuable role when power crews, rescue teams, and debris removal workers are working long, hard hours.To do this, they make sure all employees have disaster training and stock all their restaurants with generators, and have a reduced menu specifically to be offered in the aftermath of a disaster. Over time, this even led to a more formal partnership between the organizations. FEMA first responders are known to set up initial operations in Waffle House locations. Waffle House now reports the status of each location to FEMA after a disaster to facilitate data collection.The Waffle House Index is a red, yellow, or green marker placed on a map wherever a Waffle House location is found. Under normal conditions, the marker is green. If the restaurant has shifted into emergency operations and is offering their limited menu, the marker is yellow. If the marker is red, that means that the Waffle House is closed – either the site itself is damaged or destroyed, emergency staff can not reach the site, the emergency generators are down or out of fuel, or there is a food shortage. When FEMA sees one or more reds, they know an area is in particularly bad shape – and they’ll need to help.What can you learn about risk-based thinking from the Waffle House index? Three things: first, that you can (and should) look outside your organization for risk indicators that might help you make better (and faster) decisions, particularly when those risks are activated. Second, that you should explore crowdsourced risk data as a source of up-to-date information.And finally – if Waffle House is closed, there’s a serious problem.AdditionalReading: McKnight, B., & Linnenluecke, M.

[Note: I’ve been away from the blog for several months now in the middle of very significant changes in my life. That’s about to change! In the next post, I’ll tell you about what happened and what my plans are for the future. In the meantime, I wanted to share something that happened to me today.]
A couple hours ago, I went to the ATM machine.
I don’t use cash often, so I haven’t been to an ATM machine in several months. Regardless, I’m fully accustomed to the pattern: put card in, enter secret code, tell the machine what I want, get my money, take my card. This time, I was really surprised by how long it was taking for my money to pop out.
Maybe there’s a problem with the connectivity? Maybe I should check back later? I sat in my car thinking about what the best plan of action would be… and then I decided to read the screen. (Who needs to read the screen? We all know what’s supposed to happen… so much so, that I was able to use an ATM machine entirely in the Icelandic language once.)
PLEASE TAKE YOUR CARD TO DISPENSE FUNDS, it said.
This is one of the simplest and greatest examples of poka-yoke (or “mistake-proofing”) I’ve ever seen. I had to take my card out and put it away before I could get my money! I was highly motivated to get the money (I mean, that’s the specific thing I came to the ATM to get) so of course I’m going to do whatever is required to accomplish my goal. The machine was forcing me to take my card — preventing the mistake of me accidentally leaving my card in the machine — which could be problematic for both me and the bank.
Why have I never seen this before? Why don’t other ATMs do this? I went on an intellectual fishing expedition and found out that no, the idea is not new… Lockton et al. (2010) described it like this:
A major opportunity for error with historic ATMs came from a user leaving his or her ATM card in the machine’s slot after the procedure of dispensing cash or other account activity was complete (Rogers et al., 1996, Rogers and Fisk, 1997). This was primarily because the cash was dispensed before the card was returned (i.e. a different sequence for Plan 3 in the HTA of Fig. 3), leading to a postcompletion error—“errors such as leaving the original document behind in a photocopier… [or] forgetting to replace the gas cap after filling the tank” (Byrne and Bovair, 1997). Postcompletion error is an error of omission (Matthews et al., 2000); the user’s main goal (Plan 0 in Fig. 3) of getting cash was completed so the further “hanging postcompletion action” (Chung and Byrne, 2008) of retrieving the card was easily forgotten.
The obvious design solution was, as Chung and Byrne (2008) put it, “to place the hanging postcompletion action ‘on the critical path’ to reduce or eliminate [its] omission” and this is what the majority of current ATMs feature (Freed and Remington, 2000): an interlock forcing function (Norman, 1988) or control poka-yoke (Shingo, 1986), requiring the user to remove the card before the cash is dispensed. Zimmerman and Bridger (2000) found that a ‘card-returned-then-cash-dispensed’ ATM dialogue design was at least 22% more efficient (in withdrawal time) and resulted in 100% fewer lost cards (i.e. none) compared with a ‘cash-dispensed-then-card-returned’ dialogue design.
I don’t think the most compelling message here has anything to do with design or ATMs, but with the value of hidden gems tucked into research papers. There is a long lag time between recording genius ideas and making them broadly available to help people. One of my goals over the next few years is to help as many of these nuggets get into the mainstream as possible. If you’ve got some findings that you think would benefit the entire quality community (or quality management systems or software), get in touch… I want to hear from you!

In previous articles, we introduced Quality 4.0, the pursuit of performance excellence as an integral part of an organization’s digital transformation. It’s one aspect of Industry 4.0 transformation towards intelligent automation: smart, hyperconnected(*) agents deployed in environments where humans and machines cooperate and leverage data to achieve shared goals.
Automation is a spectrum: an operator can specify a process that a computer or intelligent agent executes, the computer can make decisions for an operator to approve or adjust, or the computer can make and execute all decisions. Similarly, machine intelligence is a spectrum: an algorithm can provide advice, take action with approvals or adjustments, or take action on its own. We have to decide what value is generated when we introduce various degrees of intelligence and automation in our organizations.
How can Quality 4.0 help your organization? How can you improve the performance of your people, projects, products, and entire organizations by implementing technologies like artificial intelligence, machine learning, robotic process automation, and blockchain?
A value proposition is a statement that explains what benefits a product or activity will deliver. Quality 4.0 initiatives have these kinds of value propositions:
Augment (or improve upon) human intelligence
Increase the speed and quality of decision-making
Improve transparency, traceability, and auditability
Anticipate changes, reveal biases, and adapt to new circumstances and knowledge
Evolve relationships and organizational boundaries to reveal opportunities for continuous improvement and new business models
Learn how to learn; cultivate self-awareness and other-awareness as a skill
Quality 4.0 initiatives add intelligence to monitoring and managing operations – for example, predictive maintenance can help you anticipate equipment failures and proactively reduce downtime. They can help you assess supply chain risk on an ongoing basis, or help you decide whether to take corrective action. They can also improve help you improve cybersecurity: documenting and benchmarking processes can provide a basis for detecting anomalies, and understanding expected performance can help you detect potential attacks.

Artist’s rendering of Bitcoin. THERE ARE NO ACTUAL COINS THAT LOOK LIKE THIS. Don’t ever let anyone sell you one.
Today, many cryptocurrencies lost ~35-50% of their value. Reddit even posted contact information for the National Suicide Prevention Hotline in /r/cryptocurrency, knowing how emotional investors were bound to be today. Bitcoin, which was nearly $20K in mid-December and has been hovering near $14K this past week, dropped nearly $4K and almost sunk below the $10K milestone. I usually track the price of Bitcoin at http://bitcointicker.co, which can show the posted prices from several exchanges (web locations where people go to buy and sell, like Ebay). There are hundreds of cryptocurrencies and many of them dropped in value today.
Why did the prices drop so much on Tuesday? Here are some likely influences:
The government of South Korea announced its plans to prepare a bill banning cryptocurrency trading (specifically Bitcoin, Ethereum, Ripple); trading volume has been high in South Korea this past year, and the transactions have propped up global cryptocurrency prices.
Market prices are usually driven by supply and demand — for example, if there aren’t that many lobsters available in a particular area at a particular time, and you go to a restaurant hoping to order one — you’ll pay a premium. But that price is also influenced by the quality of the product, the image of the product, which influences your perception of its value. Quality reflects how well something satisfies stated and implied needs or expectations.
Value, however, is quality relative to price, and influenced by image. And people are not always rational: they’ll pay a premium for image, even if the value of a product isn’t particularly high. Just think of all the Macs on display at schools, coffee shops, and airports. Price is related to value… usually, price goes up as value goes up.
Where’s the value of cryptocurrency? A Bitcoin does not, on its own, have any inherent value — just like a dollar or a Euro (a “fiat currency”). But the prospect of an asset that will increase in perceived value — where you can buy low, hold (sometimes just for a few days), and sell high because there are lots of people willing to buy it from you — will have perceived value. Hundreds of early adopters — or “Bitcoin millionaires” — are getting people excited about the prospect of making small investments and reaping huge rewards. That this has happened so recently lends a mystique to ownership of cryptocurrencies and Altcoins (or “alternatives to Bitcoin,” like Ether) in addition to the novelty.
Value is attributed to things by people, and cryptocurrencies are no exception. The quality of the currency itself, and the technical solidity of the platform upon which one is based, isn’t really tied to the cryptocurrency price right now — although this will probably change as knowledge and awareness increases.
Is this the end of Bitcoin? That’s doubtful — there are too many innovators who insist on exploring the technological landscape of cryptocurrencies and blockchain technology, and lots of investors willing to fund them. In the meantime, there are unlikely benefits: because cryptocurrencies are not yet mainstream, a “crypto crash” is not as likely to ripple through the whole economy (no pun intended) like the subprime mortgage crisis of 2008. But if you do decide to buy cryptocurrency, don’t invest any more than you can afford to lose.
We’re teaching a class on blockchain and cryptocurrencies this semester, and since the field is so new and changing rapidly, we’ve asked our students to make finding and reviewing articles part of their learning practice this semester. This is a particularly challenging topic for this task because there’s so much hype, marketing, and fluff around these topics. We want to slice through that, and improve the signal-to-noise for people new to learning about blockchain and cryptocurrencies. Here are some tips I just prepared for our students — they may be helpful to anyone writing article reviews, especially for technology-related areas.
0 – Type of Source. Reviews or articles from from arXiv, Google Scholar were strong; reviews from Coindesk, CNN were weak; reviews from WSJ and Hacker Noon went both ways. Here are two submissions that were publishable with only minor edits:
1 – Spelling & Grammar. Most of you are college seniors, and the few who aren’t… are juniors. Please use complete sentences that make sense, with words that are spelled correctly! If this is hard for you, remember that every one of you has spell check. One way to remember this is to draft your posts in Word, and then perform spell check before you copy and paste what you wrote into WordPress.
1 – Your job is to create the TL;DR. What’s the essential substance of the source you’re reviewing? What are the main lessons or findings? If you were taking notes for an exam, what elements would you capture? (Using this perspective, commentary about how good or bad you think the article was, or what it didn’t cover well, would not help you on an exam.)
2 – Choose solid source material — primary sources, e.g. research papers, if possible. If the article is less than ~400-500 words, it’s probably not detailed enough to write a 250-300 word summary/analysis. Your job in this class is to break down complex topics & help people understand them. If your article is short and already very easy to understand, there’s nothing for you to do.
3 – Avoid “weasel words” (phrases or sentences that sound like marketing or clickbait but actually say nothing) and words/sentences that sound like you’re writing a Yelp or Amazon review rather than a critical academic review. Here are a couple weaselly examples drawn from this week’s draft posts (see if you can spot what’s wrong):
It is clear how beneficial blockchain can be to smaller businesses.
Blockchain has the potential to change the world.
Each other the topics covered in the article deserve their own piece and could be augmented upon greatly.
There is a degree of uncertainty that comes with an emerging technology.
Blockchain can bring them into the 21st century to compete with larger corporations.
Many people are scared of the changes, and governments will seek to regulate it.
4 – Answer the “so what” question. Why is this topic interesting or compelling?
5 – Choose information-rich tags. For example, in our class, don’t include blockchain as a tag… pretty much everything we do will be related to blockchain, and everyone will tend to use it, so there won’t be much information contained in the tag.
