Even if you purchase reliable tools, you’ll need to plan for tools that break. When they break, what is your maintenance plan? Who will fix it: teachers, students, or technology staff? The key is to make a plan.
It is also crucial that there are processes in place which simplify the repair cycle. Is it easy for teachers to submit repair orders? Do some of them get lost? At my school, we created processes for users (mostly teachers) to follow. This came about because many teachers thought it would be convenient to just stop us in the hall and tell us that a printer had broken or that a projector was glitchy. The problem with that system was that sometimes those things fell through the cracks. So, we created a system to handle broken things efficiently and we did not regret it. Put these systems into effect and you won’t regret it, either.
