From my experience of having worked in many large multi national corporations , it is not unusual to find many mini applications running out of someone's desktop tucked away under the table or in a cupboard somewhere. They seem to largely cater to automation tasks that someone in the business had asked a developer to develop or something a developer had developed that has become the norm. I still see a lot of excel macros and spreadsheet consolidation "applications" that have graduated from the cottage industries within the organisation. Having said that they never ever tend to be business critical. They dont run the business. These are the types of stuff that will make a few business operations folks lives easier. They are not meant to run the business. Any large business that has an application that is responsible for revenue to the tune of millions would definitely be audited frequently. If and big If this is true , the controls and oversight process is horrendous in this case
