No, you didn't take that far enough.
Of course, that would require IT to buy, install, administer these simple tools, maybe take the time to learn how to use tools, which is not free, and for the requesting department to fund all of it, and we all know that is asking too much.
That last part about funding is the sticking point. Sure, there is some stretch room for manpower, but it all costs money. Everyone has to justify their budget, from marketing, to sales, to IT, to software engineering, to industrial hardware support, to archiving, to facilities maintenance, to HR, to legal, and to probably other things that I am likely forgetting.
As a caveat to those who talk about IT being a cost and sales bringing in the money, I am not in IT. For any company to be even moderately successful, you must be a team. Get rid of any relevant department to your company above, and it will fail. No toilets? No PBX system? No intranet? No Internet? No Email? Your PC not functioning? No heating/air conditioning? No copier/printer? Signing contracts without legal advice? And on and on?
You are fucked.
Granted this is not as important at 5 employees. Think about 500 employees,or 5000.
And I have a slight problem with sales in any company over about 50 people or so. They will gladly srew over the customer and 70% of their workforce for their own benefit.
