Assumptions about the users’ capacity to operate the devices, adapt to changes, and operate the systems effectively all affect how systems are designed. For those who have experience managing IT in organizations where all the users are adults and those who have completed typical IT programs in schools (including trade schools, community colleges, and universities) make very different assumptions about IT users than are true of school users. Many IT professionals who honed their craft in organizations other than K-12 schools find school users are unfamiliar and the strategies that produce usable systems in other organizations are not effective in schools, or at least they are less effective than they are in other organizations.
