Remember that information systems often have a mixture of information. Some may be sensitive and must be hidden from other people. It might be Social Security numbers, age, voting history, salary, etc., etc., etc.
So the information must be organized so that certain people can get the information that they need and are allowed to get, but do not have access to information that they should not be allowed to get.
That all takes planning, manpower, computer equipment, software designed to give certain users the right information, passwords, coordination with management to get it all right.
It doesn't happen by magic.

Don't forget that every business process needs to be reviewed and updated to use the new system, and that everybody involved needs to be trained on the new system and the new processes.

And the transition to the new system must be done in such a way that the business continues to function, and doesn't lose the data from the old system.

None of that happens by magic, and none of it happens for free: people need to be paid to do this, and if it prevents them from doing their regular jobs in the meantime then other people need to be paid to do those.

There are generally two approaches to IT systems within an organisation or corporation.

1) Separate your IT director from the rest of the company and let him/her and their staff play with technology.

2) Give the IT director an objective to develop systems that support the business objectives and to maximise the benefit to the business of what the IT department produces.

Most IT people prefer 1) and just want to be left alone to play with technology!

And without planning what you need and what the company wants to get out of the system, it will not do its intended job properly.
