Risk-aversion, cost of relatively small changes can look large, and the tendency to "design by committee". You can send an email out to some colleagues throughout other units of the business and get inundated with reasons why it won't work, and edge-cases you need to handle, whereas if you'd just implemented it, they'd likely work-around or improve their processes and everyone would have been better off.
