Proprietary and Confidential 2/29 08:31 Damon Poole  Founder/CTO of AccuRev, the leader in Agile SCM.  Focused on methodology for 17 years  Designer/architect of award-winning software  Creator of Hyper Agile methodology  Most recent product, AccuWorkflow, developed using Hyper Agile  Author of various articles on Agile development

Proprietary and Confidential 3/29 08:31 Problems with Traditional Development  Poor usability  Slow to respond to customer/market demand  Extremely difficult to accurately predict  Questionable quality  Lots of inefficiencies from rework and cancelled or shelved work  Hard to see the root cause of problems  “This time we’ll do it right!”  Burnout, job dissatisfaction

Proprietary and Confidential 4/29 08:31 Problems with Agile Development  Exact benefits are often poorly articulated  The exact relationships between specific practices and specific benefits are poorly articulated  The perception that:  it scales poorly/it is only for small teams  you need to use 3x5 cards, collocation, and pair programming  it requires generalists  it requires a team of all senior engineers  Confusion about what exactly to do (“Agile isn’t a methodology, it is a set of principles”)

Proprietary and Confidential 5/29 08:31 Requirements for Mainstream Agile  Clear benefits  Uses existing team members  Independent of application domain  Can be adopted piecemeal  Straightforward implementation  Scaleable  Appropriate for distributed development  How and why it works is obvious to everyone involved
