Most companies approach software development as follows:
 dream up a project.
 set a date for launch
 hire a bunch of coders
 whip them until they’re half dead.
 hire some testers
 testers reports bugs
 PM blames testers for bugs while reporting ‘green’
 Business has no idea what was accomplished
 Time passes quickly…Its already 2years
 Unfortunately the market has changed and we are out with the
project is technically obsolete
Start over.

Concept first discussed by H. Takeuchi
and I. Nonaka in their seminal HBR article
"The New New Product Development
Game“ (Jan 1986)

Jeff Sutherland was frustrated by this cycle
and wanted to deploy new products fast
without the ‘death-march’ aspect. He
discovered Scrum in an HBR article and
first implemented it in 1993 at Easel Corp.

experiences borrows from Lean
