If someone has an idea of an improvement to make, they can put forward a business case for it. Then it gets reviewed by someone in management, and if they agree then time/resource/etc are allocated when scheduling permits. And when I say "business case", I don't mean anything particular formal or structured. Essentially just: * This is what I want to do. * This is the problem it solves. * I will need $days and $resources to do it. In terms of how they actually submit the request, it's done by creating an issue on one of our issue tackers (depending on what its related to), which can then either be reviewed asynchronously or discussed directly if required.
