I frequently work with organizations at the lower end of the maturity scale, due to no fault of their own. In many cases business has rapidly outgrown the IT capability or capacity to support them, or there was a conscious prior decision to outsource much of the IT operation and is now being brought back in house albeit without the people or process infrastructure to support it. In these cases, IT Departments which demand to have solid business cases before they undertake any new work are doing themselves and their organizations a disservice.
