2. develop a working prototype
3. use the prototype
4. if the user is satisfied, move to the operational prototype. If not, revise and enhance the prototype

Question 4

define end-user development

Answer 4

• allows end users to create simple information systems with little or no assistance from specialists
• rapid development, higher user involvement, and satisfaction

Question 5

define rapid application development (RAD) and Joint application design (JAD)

Answer 5

• RAD: creating workable systems in a short period
• JAD: end users and information systems specialists working together on design

Question 6

difference between agile and scrum

Answer 6

• agile involves frequent face-to-face meetings to modify, refine and test how the system meets user needs
• scrum is an agile ISD methodology focusing on iterative development through cycles called “sprints:

Question 7

Answer 7

• product backlog: a list of high-level features required by the product owner
• sprint backlog: selected requirements for each sprint, quarantined from further changes during the sprint
• sprint: a 2 to 3 week cycle where the scrum team designs, codes and tests software
• daily stand-up meetings: brief meetings for updating information
• sprint review: at the end of each sprint, the team presents what it has accomplished
• sprint retrospective: evaluates the sprint process to identify improvements

Question 8

Question 12

compare waterfall vs agile

Answer 12

• waterfall: sequential, all requirements defined upfront, less adaptable to change
• agile: iterative. requirements evolve incrementally, highly adaptable to change
  success rate:
• agile has higher success rate across projects of all sizes compared to waterfall
