It’s always useful to carry out what I call an ICT health check. It’s like a medical health check: rather than wait for symptoms of disease to manifest themselves, it is far better to be proactive and have a “once over” every so often, say once a year. We rarely do, of course. Another analogy might be farmers’ footing, the practice whereby a farmer will walk around the farm every day to make sure no fences have blown down or anything like that. In short, the idea of a health check is to nip any potential problems in the bud. So what should an ICT health check look like?
