Applying Agile Methodology- Harmeet Sudan, PMP 2011 Capgemini. All rights reserved.1Waterfall vs. AgileThe Waterfall approach to product development may conflict with the goals of maximum speed and flexibility. Instead a holistic or rugby approach where a team tries to go the distance as a unit, passing the ball back and forth may better serve todays competitive requirements.

Rather than doing all of one thing at a time......Scrum teams do a little of everything all the timeRequirementsDesignCodeTestSequential vs. overlapping development4Scrum is an agile process that allows us to focus on delivering the highest business value in the shortest time.It allows us to rapidly and repeatedly inspect actual working software (every two weeks to one month).The business sets the priorities. Teams self-organize to determine the best way to deliver the highest priority features.Every two weeks to a month anyone can see real working software and decide to release it as is or continue to enhance it for another sprint.Scrum in 100 words5Self-organizing teamsProduct progresses in a series of month-long sprintsRequirements are captured as items in a list of product backlogNo specific engineering practices prescribedUses generative rules to create an agile environment for delivering projectsOne of the agile processes
