     92 We are wasting up to 20% of our time on computer problems, says study

     97 
     98 Even though our computers are now better than 15 years ago, they still
     99 malfunction 11%–20% of the time, a new study from the University of Copenhagen
    100 and Roskilde University concludes. The researchers behind the study therefore
    101 find that there are major gains to be achieved for society by rethinking the
    102 systems and involving users more in their development.
    103 
    104 An endlessly rotating beach ball, a program that [56]crashes without saving
    105 data or systems that require illogical procedures or simply do not work:
    106 Unfortunately, struggling with computers is still a familiar situation for most
    107 of us. Tearing your hair out over computers that do not work remains very
    108 common among users, according to new Danish research.
    109 
    110 In fact, so much that on average, we waste 11%–20% of our time in front of our
    111 computers on systems that do not work or that are so difficult to understand
    112 that we cannot perform the task we want to. And this is far from being good
    113 enough, says Professor Kasper Hornbæk, one of the researchers behind the study.
    114 
    115 "It's incredible that the figure is so high. However, most people experience
    116 frustration when using computers and can tell a horror story about an important
    117 PowerPoint presentation that was not saved or a system that crashed at a
    118 critical moment. Everyone knows that it is difficult to create IT systems that
    119 match people's needs, but the figure should be much lower, and one thing that
    120 it shows is that [57]ordinary people aren't involved enough when the systems
    121 are developed," he says.
    122 
    123 Professor Morten Hertzum, the other researcher behind the study, emphasizes
    124 that most frustrations are experienced in connection with the performance of
    125 completely ordinary tasks.
    126 
    127 "The frustrations are not due to people using their computers for something
    128 highly advanced, but because they experience problems in their performance of
    129 everyday tasks. This makes it easier to involve users in identifying problems.
    130 But it also means that problems that are not identified and solved will
    131 probably frustrate a large number of users," says Morten Hertzum.
    132 
    133 [INS::INS]
    134 
    135 The problems are only too recognizable
    136 
    137 To examine this issue, the researchers have been assisted by 234 participants
    138 who spend between six and eight hours in front of a computer in their
    139 day-to-day work.
    140 
    141 During one hour, the researchers told them to report the situations in which
    142 the computer would not work properly, or where the participants were frustrated
    143 about not being able to perform the task they wanted.
    144 
    145 The problems most often experienced by the participants included: "the system
    146 was slow," "the system froze temporarily," "the system crashed," "it is
    147 difficult to find things." The participants had backgrounds such as student,
    148 accountant, consultant, but several of them actually worked in the IT industry.
    149 
    150 "A number of the participants in the survey were IT professionals, while most
    151 of the other participants were highly competent IT and computer users.
    152 Nevertheless, they encountered these problems, and it turns out that this
    153 involves some fundamental functions," says Kasper Hornbæk.
    154 
    155 The participants in the survey also responded that 84% of the episodes had
    156 occurred before and that 87% of the episodes could happen again. And, according
    157 to Kasper Hornbæk, we are having the same fundamental problems today that we
    158 had 15–20 years ago.
    159 
    160 "The two biggest categories of problems are still about insufficient
    161 performance and lack of user-friendliness," he says.
    162 
    163 Morten Hertzum adds, "Our technology can do more today, and it has also become
    164 better, but at the same time, we expect more from it. Even though downloads are
    165 faster now, they are often still experienced as frustratingly slow. "
    166 
    167 88% use a computer at work
    168 
    169 According to Statistics Denmark, 88% of Danes used computers, laptops,
    170 smartphones, tablets or other mobile devices at work in 2018. In this context,
    171 the new study indicates that a half to a whole day of a normal working week may
    172 be wasted on computer problems.
    173 
    174 "There is a lot of productivity lost in workplaces throughout Denmark because
    175 people are unable to perform their ordinary work because the computer is not
    176 running as it should. It also causes a lot of frustrations for the individual
    177 user," says Kasper Hornbæk.
    178 
    179 This means that there are major benefits to be gained for society if we
    180 experienced fewer problems in front of our computers. According to Kasper
    181 Hornbæk, the gains can, for example, be achieved if more resources are invested
    182 in rethinking how faults are presented to us on the computer.
    183 
    184 "Part of the solution may be to shield us from knowing that the computer is
    185 working to solve a problem. In reality, there is no reason why we need to look
    186 at an incomprehensible box with commands or a frozen computer. The [58]computer
    187 could easily solve the problems without displaying this, while it provided a
    188 back-up version of the system for us, so that we could continue to work with
    189 our tasks undisturbed," says Kasper Hornbæk.
    190 
    191 At the same time, IT developers should involve the users even more when
    192 designing the systems to make them as easy to use—and understand—as possible,
    193 because according to the researcher, there are no poor IT users, only poor
    194 systems.
    195 
    196 "When we're all surrounded by IT systems that we're cursing, it's very healthy
    197 to ascertain that it's probably not the [59]users that are the problem, but
    198 those who make the systems. The study clearly shows that there is still much
    199 room for improvement, and we therefore hope that it can create more focus on
    200 making more user-friendly systems in the future," concludes Kasper Hornbæk.
