After 20 years in software development, my frustations with watching organizations hurt themselves from bad practices finally boiled over in my article, Reality Driven Development. The response and discussion from Hacker News lead me into the work of Donald Reinertsen, who laid out the math that validated everything I was experiencing. Much of the Scaled Agile Framework is based on his work, which lead into my journey with SAFe 3 years ago. Join me on December 9th for my first class, Leading SAFe 5.1.
