Agile


Comparison of methods

Waterfall Iterative Agile

Strengths • Easy to understand• Supports creation of detailed

plan

• Deliver business value• Responsive to change

• Faster time-to-market• Constant feedback• Highest business value

delivered early

Weaknesses • Brittle if requirements change• Wasteful if business strategy

changes• Big Up Front Planning / Design

• Requires mind shift• Increased uncertainty for “far”

iterations• Fixed feature / price contracts

• Dependency on people and their interactions creates cultural resistance to change

• Hazardous if not ALL parties embrace the Agile Manifesto

Project Suitability • Legacy environment• Stable team with significant

domain / technology experience

• Minimal change

• Fluid requirements• New / untried technology• Cohesive teams, even if

geographically dispersed

• Evolving requirements• Niche technologies / few

legacy dependencies• Dependent on end user
