We have had great success simply by involving staff from i.e. the project department in our fast track development projects. Once they have participated, been part of it, they know it is not the wild west. Developed in hippie land. By innovation freaks. It is about doing only things that improve the product. And knowing instead of guessing and hoping. And it gives the software engineer the opportunity to do his or her very best. And that is value for money too!
