There's no incentive to improve it and lots of disincentive to change at all. In software projects I was often brought in by clients when the CEO realized they had fallen way behind competitors. What you would find was layers of process built over years as an immune response to any mistake ever made. No VP was willing to put their name on removing any part of that process because the upside was "things are 5% more efficient" and the downside was "Sheila removed the process and it broke, so she should be fired".
