Agile is good beginning, but just that, a beginning.
Over the last ten years Agile has become a best practice, but a best practice is also a common practice.
If you are just practicing Agile then you are making no difference with any other.
I have worked with several methodologies over the years, from heavy ISO/IEC standards or Prince2 to eXtreme Programming.
I have arrived to something called Dragoon Dreaming which is a kind of nearly bug free code that provide great user experiences.
Agile is a set of methodologies that focus on delivering the maximum amount of code as soon as possible.
I believe in delivering actual Return Of Invesment to the software maker and not just more lines of code.
My biggest team was one that I had at ThyssenKrupp with over 40 developers for the updating of its ERP to .NET technology during 18 months.
I have experience writing commercial proposals, scheduling projects, doing budgets, controlling execution, recuiting people, motivating high performance teams, gaining executive support at organizations and reducing the deployment friction of applications.
