So. Two international organisations that were based in London are now moving to France and the Netherlands. The UK has lost its seat on the world court in the Hague for the 1st time in…ever, and people are writing things like this:

“the decision to bow to mounting opposition within the UN general assembly is a humiliating blow to British international prestige and an acceptance of a diminished status in international affairs.”

Ya think Europe is going to let the UK have its cake and eat it too, without any sort of fuss? Idjits.

I was given a leaflet on the perils of cannabis this weekend. The information contained hasn’t really been updated since the Reagan “just say no” days, and is pretty much on par with reefer madness. 

The snark is strong in this one.

Across 33 rich countries, only 5% of the population has high computer-related abilities, and only a third of people can complete medium-complexity tasks.

One of usability’s most hard-earned lessons is that you are not the user. This is why it’s a disaster to guess at the users’ needs. Since designers are so different from the majority of the target audience, it’s not just irrelevant what you like or what you think is easy to use — it’s often misleading to rely on such personal preferences.

For sure, anybody who works on a design project will have a more accurate and detailed mental model of the user interface than an outsider. If you target a broad consumer audience, you will also have a higher IQ than your average user, higher literacy levels, and, most likely, you’ll be younger and experience less age-driven degradation of your abilities than many of your users.

There is one more difference between you and the average user that’s even more damaging to your ability to predict what will be a good user interface: skills in using computers, the Internet, and technology in general. Anybody who’s on a web-design team or other user experience project is a veritable supergeek compared with the average population. This not just true for the developers. Even the less-technical team members are only “less-technical” in comparison with the engineers. They still have much stronger technical skills than most normal people.

OECD Skills Research

A recent international research study allows us to quantify the difference between the broad population and the tech elite. The data was collected from 2011–2015 in 33 countries and was published in 2016 by the OECD (the Organisation for Economic Co-operation and Development, a club of industrialized countries). In total, 215,942 people were tested, with at least 5,000 participants in most countries. The large scale of this study explains why it took a few years to publish the findings.

The research aimed to test the skills of people aged 16–65, which is the age range referred to as “adults” in the report. While it’s true that people aged 66+ are rare in the workforce (and thus of less interest to this workforce-targeted project), they are a major user group for many websites. Our research with users older than 65 has found many important usability issues for this age segment, who often has lower technology skills than younger users. Thus, in assessing the OECD findings, we should remember that the full user pool has lower skills than what the study data shows.

The OECD project looked at a broad range of job-related skills, but of most interest to us is the test of technology skills. For this part of the study, participants were asked to perform 14 computer-based tasks. Instead of using live websites, the participants attempted the tasks on simulated software on the test facilitator’s computer. This allowed the researchers to make sure that all participants were confronted with the same level of difficulty across the years and enabled controlled translations of the user interfaces into each country’s local language.

The tasks ranged in difficulty from very straightforward to somewhat complicated. One of the easy tasks was to use the reply-all feature for an email program to send a response to three people. This was easy because the problem was explicit and involved a single step and a single constraint (the three people).

One of the difficult tasks was to schedule a meeting room in a scheduling application, using information contained in several email messages. This was difficult because the problem statement was implicit and involved multiple steps and multiple constraints. It would have been much easier to solve the explicitly stated problem of booking room A for Wednesday at 3pm, but having to determine the ultimate need based on piecing together many pieces of info from across separate applications made this a difficult job for many users.
Even the supposedly difficult tasks don’t sound that hard and I certainly expect all of my readers to be able to perform them speedily and with a high degree of confidence. However, my entire point is that just because you can do it, it doesn’t mean that the average user can do so as well.

The 4 Levels of Technology Proficiency

The researchers defined 4 levels of proficiency, based on the types of tasks users can complete successfully. For each level, here’s the percentage of the population (averaged across the OECD countries) who performed at that level, as well as the report’s definition of the ability of people within that level.

“Below Level 1” = 14% of Adult Population
Being too polite to use a term like “level zero,” the OECD researchers refer to the lowest skill level as “below level 1.” This is what people below level 1 can do: “Tasks are based on well-defined problems involving the use of only one function within a generic interface to meet one explicit criterion without any categorical or inferential reasoning, or transforming of information. Few steps are required and no sub-goal has to be generated.”
An example of task at this level is “Delete this email message” in an email app.

Level 1 = 29% of Adult Population
This is what level-1 people can do: “Tasks typically require the use of widely available and familiar technology applications, such as email software or a web browser. There is little or no navigation required to access the information or commands required to solve the problem. The problem may be solved regardless of the respondent’s awareness and use of specific tools and functions (e.g. a sort function). The tasks involve few steps and a minimal number of operators. At the cognitive level, the respondent can readily infer the goal from the task statement; problem resolution requires the respondent to apply explicit criteria; and there are few monitoring demands (e.g. the respondent does not have to check whether he or she has used the appropriate procedure or made progress towards the solution). Identifying content and operators can be done through simple match. Only simple forms of reasoning, such as assigning items to categories, are required; there is no need to contrast or integrate information.”

The reply-to-all task described above requires level-1 skills. Another example of level-1 task is “Find all emails from John Smith.”

Level 2 = 26% of Adult Population
This is what level-2 people can do: “At this level, tasks typically require the use of both generic and more specific technology applications. For instance, the respondent may have to make use of a novel online form. Some navigation across pages and applications is required to solve the problem. The use of tools (e.g. a sort function) can facilitate the resolution of the problem. The task may involve multiple steps and operators. The goal of the problem may have to be defined by the respondent, though the criteria to be met are explicit. There are higher monitoring demands. Some unexpected outcomes or impasses may appear. The task may require evaluating the relevance of a set of items to discard distractors. Some integration and inferential reasoning may be needed.”

An example of level-2 task is “You want to find a sustainability-related document that was sent to you by John Smith in October last year.”

Level 3 = 5% of Adult Population
This is what this most-skilled group of people can do: “At this level, tasks typically require the use of both generic and more specific technology applications. Some navigation across pages and applications is required to solve the problem. The use of tools (e.g. a sort function) is required to make progress towards the solution. The task may involve multiple steps and operators. The goal of the problem may have to be defined by the respondent, and the criteria to be met may or may not be explicit. There are typically high monitoring demands. Unexpected outcomes and impasses are likely to occur. The task may require evaluating the relevance and reliability of information in order to discard distractors. Integration and inferential reasoning may be needed to a large extent.”

The meeting room task described above requires level-3 skills. Another example of level-3 task is “You want to know what percentage of the emails sent by John Smith last month were about sustainability.”

Can’t Use Computers = 26% of Adult Population
The numbers for the 4 skill levels don’t sum to 100% because a large proportion of the respondents never attempted the tasks, being unable to use computers. In total, across the OECD countries, 26% of adults were unable to use a computer.

That one quarter of the population can’t use a computer at all is the most serious element of the digital divide. To a great extent, this problem is caused by computers still being much too complicated for many people.

Tech Skills by Country

You might say that you’re not designing for the whole of the OECD. You’re only designing for the rich and privileged country in which you most likely live. Fair enough, but the conclusions don’t change much, even when we look at the richest countries, as shown in the following chart (which is sorted in ascending order by the number of people at the highest skill level — i.e., people like yourself):

Data from the OECD study of technical skills show the distribution among skill levels across countries as well as the average for all OECD countries.
(Scandinavia is the average of Denmark, Finland, Norway, and Sweden. The UK is the population-weighted average of England and Northern Ireland, since Scotland and Wales didn’t participate in the research.)

Although there’s a lot of variation in the number of people who can’t use a computer at all, there are only very slight differences in the number of people at the highest skill level.

Overall, people with strong technology skills make up a 5–8% sliver of their country’s population, whatever rich country they may be coming from. Go back to the OECD’s definition of the level-3 skills, quoted above. Consider defining your goals based on implicit criteria. Or overcoming unexpected outcomes and impasses while using the computer. Or evaluating the relevance and reliability of information in order to discard distractors. Do these sound like something you are capable of? Of course they do.

What’s important is to remember that 95% of the population in the United States (93% in Northern Europe; 92% in rich Asia) cannot do these things.
You can do it; 92%–95% of the population can’t.

What does this simple fact tell us? You are not the user, unless you’re designing for an elite audience. (And even if you do target, say, a B2B audience of nothing but engineers, they still know much less about your specific product than you do, so you’re still not the user.)
If you think something is easy, or that “surely people can do this simple thing on our website,” then you may very well be wrong.

If you want to target a broad consumer audience, it’s safest to assume that users’ skills are those specified for level 1. (But, remember that 14% of adults have even poorer skills, even disregarding the many who can’t use a computer at all.)

conclusion: keep it extremely simple, or two thirds of the population can’t use your design.

Nestlé has announced a reorganisation of its infant nutrition business and the departure of its chief technology officer in the latest strategy changes by new chief executive Mark Schneider.

The Swiss company said its baby foods business, around which it was founded more than 150 years ago, would in future be regionally rather the globally managed. The move, announced on Wednesday, is the latest attempt by the world’s big consumer groups to shorten reporting lines in order to compete better with local rivals and start-ups.

Nestlé is the world’s largest food and drinks company. Mr Schneider, who took over as Nestlé boss at the start of the year, has identified infant nutrition as future growth opportunity. Nestlé said heads of the infant foods business would be appointed for each of the Europe, Americas and Asia regions. Nestlé Nutrition had sales of SFr 10.3bn last year and operating profit margins of 22.7 per cent.

Heiko Schipper, head of Nestlé Nutrition, will leave the Swiss group at the end of the year to head the consumer health division at Bayer, the German drugs group. Separately, Nestlé said Stefan Catsicas, chief technology officer, was leaving to “pursue entrepreneurial and venture capital activities” outside the group. He will be replaced by Stefan Palzer, head of its research centre.

Nestlé is braced for overall sales growth this year to weaken further from 2016’s historical low. Mr Schneider has promised to boost the pace of expansion by focusing on markets for coffee, pet care and bottled waters as well as infant nutrition. But he has also shifted the Swiss group away from its focus on sales, and has set for the first time a target for increasing profit margins.

So, two executive VPs are added to the ever-growing list of people leaving to follow exciting opportunities, or spending more time with their family, or taking early retirement. There’s a serious tree-shaking exercise at the top, and we have no bloody clue what that’s going to mean for us peons.

Or at least he likes my stench. If he’s not on my side of the bed curled up near my pillow, he’s on my clothes.
