Scrum



Scrum

» W. Edwards Deming's philosophy: "When people and organizations focus primarily on quality, quality tends to increase and costs fall over time. However, when people and organizations focus primarily on costs, costs tend to rise and quality declines over time."

» “Fail fast”: Scum can not make sure your project will be successful but it will make your project failed within 30 days.

» Shorter cycles = Faster feedback



Scum

» "Scrum is a framework for developing complex products and systems. It is grounded in empirical process control theory. Scrum employs an iterative, incremental approach to optimize predictability and control risk."

» History

∀ In 1986, Hirotaka Takeuchi and Ikujiro Nonaka described a new approach to commercial product development that would increase speed and flexibility, based on case studies from manufacturing firms in the automotive, computer, photocopier, and printer industries

∀ In 1995, Sutherland and Schwaber jointly presented a paper describing the Scrum methodology

∀ Schwaber and Sutherland collaborated during the following years to merge the above writings, their experiences, and industry best practices into what is now known as Scrum.
