While there were numerous problems with the big corporate structures I worked in decades ago where everything was done by silos of specialists, there were huge advantages. No matter where there was a security, performance, network, hardware, etc. issue, the internal support infrastructure had the specialist’s pagers and for a problem like this, the people fixing it would have been on a conference call until it was fixed. There was always a team of specialists to diagnose and test fixes, always available developers with the expertise to write fixes if necessary, always ops to monitor and execute things, always a person in charge to make sure it all got done, and everybody knew which department it was and how to reach them 24/7.

Now if you needed to develop something not-urgent that involved, say, the performance department, database department, and your own, hope you’ve got a few months to blow on conference calls and procedure documents.

For that industry it made sense though.
