I update this article periodically to keep it current. The principles never change though.
Do things the right way.
When you (as the IT manager or contractor) hear frases like “it should be easier” or “but why can’t it just be like…” you know staff are not using the computer network in the intended way. They’re using email as a CRM or their desktop as their filing system. For example, if the businesses needs a CRM then get one and stop using email for contact management. To continue the example, staff will start to ask how they can share their contacts, calendar appointments and resource bookings. It’s a slippery slope and one you want to avoid at all costs.
