One would think that by now that software applications, online services, and electronic appliances that are poorly designed and difficult to learn and operate would be a thing of the past. After thirty years of CHI conferences, twenty years of UPA conferences, and countless books, articles, and websites about usability and interaction design, shouldn’t all software developers “get it” by now that careful task-focused design and usability are crucial for the success of interactive products and services?

Alas, it is not so. In fact, more companies than ever still don’t get it: They are churning out bad interactive products and services with little or no awareness that they are doing so, and/or no idea how to do better.

Certainly, the fields of HCI, interaction design, and usability have matured. The knowledge they have developed has spread worldwide—no longer is UI design practiced exclusively in the western, industrialized world.

Explosion in Digital Technology

However, the marketplace and the pervasiveness of interactive computer-based technology also has grown immensely. When interactive computing was first emerging, the main products were computers themselves and their operating systems and applications.

Today, just about every product—e.g., watches, cameras, telephones, microwave ovens, PDAs, GPS units, cars, music players, even toasters—has one or more computers inside it. Companies that used to make watches now make digital watches, calculators, and music players. Companies that formerly sold typewriters now sell multi-function printer-fax-copiers. Companies that once made chemical titration tubes and litmus paper now make genome sequence analysis instruments and corresponding control and analysis software. Other examples of products that have become digital include: home heating systems, home security systems, refrigerators, parking meters, transit ticket kiosks, books, thermometers, cameras, metronomes—even picture frames and toilets. Furthermore, functionalities that were formerly provided in separate devices have been merged, e.g., camera-phone-music-players, printer-fax-copiers, pen-recorders, gas-station-pump-TVs. Finally, entire new functionalities have emerged, e.g., GPS position-tracking.

In addition, the Internet’s importance today means that any company, organization, or person in the developed world will have some sort of presence on the Web and in social media. Regardless of whether this presence is a full-blown website, a blog, a Facebook “wall,” a LinkedIn profile, a YouTube channel, or a Twitter feed, the owner has to design it (within the constraints of the platform). That effectively makes every company, organization, and person with any Internet presence into a software designer, whether or not they are one in the offline world. Of course, this is especially true for companies and organizations with websites providing online services, such as sales, reservations, maps, document creation and storage, and online forms.

Many Old Companies Are Software Development Neophytes

These changes mean that the number of companies and organizations developing interactive software is exploding. Unfortunately, knowledge about interaction design and usability is absent in many companies and is not being disseminated fast enough to keep up. As a result, the proportion of interactive products created without benefit of good UI design thinking and process is growing. So usefulness and usability is falling behind.

In our experience with helping companies and organizations create usable, useful, popular products and services, we find that a large number of our clients are at what Eric Schaffer (2004) calls Usability Maturity Level 0 (clueless) or Level 1 (piecemeal usability). That is, they have no one on staff with (a) UI design or evaluation experience; (b) knowledge of the HCI literature, and in some cases knowledge that there even is such a literature; and (c) membership in professional societies devoted to human-computer interaction and usability (e.g., ACM SIGCHI, UPA, ISO TC13, and HCI International). In some companies that develop software, there are no employees who even know what interaction design is—many confuse it with graphic design.

It’s not just about knowledge; development processes add to the problem. Of course in companies that lack awareness of the need for interaction design, it is not surprising that there is little place for interaction design in their software development processes. What is surprising is the lack of a place at the product development table for interaction design at companies that do know about its importance. In our experience, we often see companies in which there are no managerial champions for usability and no organizational structures or processes to support good interaction design.

The result is that despite the arrival of innovative, useful, and easy-to-use products such as the iPhone, a great many new products are simply horrible from a usability perspective. One new toaster has a digital display and a touch pad with 14 buttons. Some companies develop appliances, then outsource the supporting utility and application software to development firms that apparently lack any interaction design skill, resulting in promising appliances with disappointing supporting software. The 1980s joke about people not knowing how to program their VCR has now broadened into the sad fact that people cannot fully control many of the appliances they own, e.g., “My oven turned itself off in the middle of baking a turkey yesterday, but I have no idea why, so I took it over to a neighbor’s house and had them bake it for me.” Alan Cooper was right when he lamented that when computer technology is added to appliances, the result is usually more like a computer than an appliance (1999). One person we know, on discovering that his new high-end car became completely inoperable when its startup-controller crashed, returned it to the dealer, saying, “I wanted a car, but what you sold me is a computer.”

It’s Getting Worse, Not Better

While knowledge of good interaction design and usability engineering principles has definitely grown and spread over the past several decades, we daresay that the number of companies and organizations producing poor interactive products and services due to sheer ignorance is larger now than three decades ago.

Most software developers, especially newcomers, focus on software technology. They hire skilled software architects and programmers. Few consider the interaction that people have with technology as a subject matter requiring experience and expertise in its own right. Fewer make interaction the focus of their design efforts. Therefore, no matter how advanced the fields of human-computer interaction, interaction design, and usability become, that knowledge does not get to those who need it to make their products useful and usable. Instead, many product developers today consider the work of using technology to be a problem for the users, not a problem for the designers or their companies.

Previous Alerts to the Problem

We of course are not the first to complain about the poor state of software design and usability. Winograd (1996) presented perspectives and recommendations on the state and future of software design from several industry experts. Tom Landauer (1996), Don Norman (1999), and Alan Cooper (1999) each devoted an entire book to describing the problem and outlining their recommended solutions. One of us (Johnson, 2000), in a book on common graphical user-interface (GUI) design mistakes, included a chapter explaining that mistakes by management are the root cause of many GUI design mistakes.

However, those arguments concerned the state of software design before the above-described recent explosive growth of digital devices and services. Over the last decade, the problem has grown much worse.

We Haven’t Hit Bottom Yet

Furthermore, the problem will continue to worsen. Although colleges, universities, technical book authors, and technical trainers are working hard to educate current and future software designers and developers in user-centered and task-centered design and usability testing, the ones being educated and trained are not the ones who make the decisions.

Middle and upper managers make the decisions, structure the organizations, allocate resources, and determine development processes, schedules, staffing, and budgets. Few managers—especially upper managers—are naturally endowed with the depth of insight that the late Steve Jobs had on the value of giving customers products and services that are productivity-enhancing, easy to use, and delightful. Most managers need education on that—lots of education. But, for the most part, they—especially upper managers—aren’t getting any such education.

Thus, in most companies, organizations, and agencies, until we change managerial thinking and practice, we can educate and train software designers and engineers all we want, but they will be severely limited in what they can do to improve how software is designed.

Our Last Hope: Teach Management to Optimize UX

To turn things around, HCI experts must convince management of the benefits of optimizing the users’ experience with digital products and services. (Another approach is for enough of us to become management, but that is harder because management requires temperaments, intuitions, and skills that many of us in the HCI field do not have. In such cases, we can hope that when we are in a position to do something, the forces at work on us in those positions will not prevent us from doing what we know must be done.)

Our previous books (Johnson, 2000; Johnson, 2007; Johnson, 2010; Johnson & Henderson, 2011) and training efforts have been aimed mainly at the engineers who design, develop, and test interactive products and services, but now we are expanding and re-directing our educational efforts toward management. One of us recently began presenting at management conferences and manager training events, and the two of us are planning a book on maximizing the user experience aimed precisely at managers.

Reaching managers requires more than just a change in vocabulary; it requires a change in mindset. Managers are generally not interested in the “how-to” details of task-focused design and usability testing; they have teams of designers and engineers for that. They need an understanding of the “what” and the “why,” presented briefly, clearly, and succinctly. For example, they need to know the following:

The above is what managers need to learn. But how do we teach it to them? How do we get the opportunity to educate managers? How do we even get an audience with them? Here are some ideas that can help:

If more people in the HCI and usability fields would turn their focus towards educating management, we might be able to turn the interactive products industry around. The dream is that many companies besides Apple will have people lined up outside stores awaiting new products and releases.

Well, we can dream, can’t we?
