I’m looking for some statistics about the costs of homegrown development. A firm I’ve been talking to is fighting a battle with their IT department – the IT department insists on building every application themselves, while marketing and management are now leaning towards buying us (a fully-built CRM system tailored to their market).
What I don’t have are numbers that identify the cost – hidden and otherwise – of homegrown software development. This seems like something that should be easy to find, but so far I’ve come up empty. Anyone care to point me in the right direction?
