You know what you want to achieve and you have a gut feeling it's relatively simple. Right?
But, your IT department says you're in a long queue of higher priority projects and it's going to take, at a minimum:
6+ months before they can start evaluating your IT request
3+ months to create the specification
6+ months to build the solution
3+ months to test, debug, document and deliver it
(Oh, and you may need to spend a large part of your budget to make it happen..)
