Number 1 most important aspect of your MIS
Before I start, you know and I know where I work, I promise you this is not advertising, promoting or research at all!
I had an interesting conversation over lunch with a contact yesterday discussing MISs in general, and he kept referring to attendance recording as the number 1, above all else by far, as the most important aspect/module of such a system in schools today.
While I cannot agree, it got me thinking if you absolutely had to have one module, or lets say 1 module working without fail all the time, which would it be within your schools.
BTW, lets not turn this into MIS bashing, or error reporting, just overall interested to hear your thoughts.
