Being an information technology, or IT, worker is not a job I envy. They are the ones who, right in the middle of a critical meeting, are expected to instantly fix the projector that’s no longer working. They have to tolerate the bad tempers of colleagues frustrated at the number of times they’ve had to call the help desk for the same issue. They are also the ones who know there are systems that are more powerful, reliable and faster, but their employer simply will not put up the funds to buy them.

        According to a recent survey, employees who have a job reliant on IT support consider IT a major source of job dissatisfaction. Through no fault of their own, they can suddenly find their productivity deteriorating or quality control non-existent. And there’s little they can do about it.

        The experience of using IT penetrates almost the entire work field. It has become a crucial part of employees’ overall work experience. When IT is operating as it should, employee self-confidence swells. Their job satisfaction, too, can surge when well-functioning machines relieve them of dull tasks or repetitive processes. But if there’s one thing that triggers widespread employee frustration, it’s an IT transformation project gone wrong, where swollen expectations have been popped and a long list of promised efficiencies have been reversed. This occurs when business leaders implement IT initiatives with little consideration of how those changes will impact the end user.

        Which is why managers should appreciate just how influential the IT user experience is to their employees, and exert substantial effort in ensuring their IT team eliminate programming errors and application crashes. Adequate and timely IT support should also be available to enable users to cope with technological issues at work. More importantly, IT practitioners need to understand what employees experience mentally when they use IT.

        Therefore, businesses need to set up their IT infrastructure so that it is designed to fit in with their employees’ work, rather than adjust their work to fit in with the company’s IT limitations.

解析：A。根据题干中的business和experience in using IT可定位至原文最后两段。倒数第二段强调了改善信息技术用户体验的重要性，最后一段则指出，因此，企业需要建立起自己的信息技术基础设施，使之与员工的工作相适应。A项与此内容相符，其中的designing systems对应最后一段中的set up their IT infrastructure，suit their needs是对fit in with their employees’ work的同义概括，故A项为正确答案。

错项排除：B项利用原文倒数第二段中的ensuring和mentally设置干扰，但mentally在这里指的是员工的“心理体验”，并不是要确保员工的心理健康，故B项排除。原文结尾提到，企业应建立起信息技术基础设施，使之与员工的工作相适应，而不是让员工调整自己的工作来适应企业在信息技术上的局限，C项与原文意思相悖，故错误。D项在原文中无依据，故排除。
