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)

6/20/20146

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.

6/20/20147

Other iconoclasts banded together to form the Agile alliance to promote Agile/Scrum methodologies.• Scrum is the management framework for product

development promoted by the alliance.

Agile though based on empirical experiences borrows from Lean Manufacturing, Six sigma, Wideband Delphi etc.

6/20/20148

We value

Individuals and interactions over processes and tools

Working software over comprehensive documentation

Customer collaboration over contract negotiation

Responding to change over following a plan

subsequent sprints.

productive work every working day.

Vacations and holidays are included in

planning.

Team decides the available capacity.

Additional specialized capacity has to be

accounted for like DBAs etc.
