Why is it worth practising EA and what is the Return on Investment? One could argue that the ROI all comes from Information and its use, so it could be a Return on Information. Firstly, if the architecture (current) is documented, it is easier for people to find information. For example, if an audit is required of all application software, the information will be readily available. In my (large) organisation the Application Architecture is reasonably well documented and it was easy to provide our new outsourcer the information to support our applications. Secondly, if the organisation wants to promote re-use of processes, applications, data and infrastructure items, it needs to have these inventorised with views that can be understood by business as well as IT development staff.
