Question 1

List

Characteristics of Agile Process

Answer 1

Not suuitable for large, high-risk, or mission-critical projects
Minimal rules and documentation
Continuous involvment of testers
Easy to accomodate product changes
Depends heavily on stakeholder interaction
Easy to manage
Early delivery of partial solutions
Informal risk management
Built in continuous process improvement

Question 2

List

Characteristics of Spiral process

Answer 2

Not suitable for small, low-risk projects
Several steps required, along with documents done up front
Early involvement of testers (might be outside of main team)
Hard to accomodate product changes until prototype completed
Continuous stakeholder involvement in planning and risk assessment
Requires formal project management and coordination
Project end not always obvious
Good risk management
Process improvment handled
