Software Development Practices and Challenges

Study Notes

Disadvantages of User Stories

Difficulty judging if enough user stories cover all requirements
Difficulty judging if a single story accurately represents an activity
Experienced users may omit details in descriptions
It is difficult to judge if enough user stories have been developed to cover all of the essential requirements
It is also difficult to judge if a single story gives a true picture of an activity.
Experienced users are often so familiar with their work that they leave out some details in their descriptions.

Incremental Development vs. Plan-Driven Development

Key difference in testing approaches
Extreme Programming (XP) emphasizes automated testing
During development, one of the important differences between incremental development and plan-driven development is in the way that the system is tested.

Extreme Programming (XP) Testing Features

Test-first development
Incremental test development from scenarios
User involvement in test development and validation
Use of automated testing frameworks
Development cannot proceed until all tests have been successfully executed.

Benefits of Incremental Development

Customers see on-time delivery of increments and receive feedback
Minimizes last-minute surprises concerning software delivery
Builds trust and a positive project culture
Customers see on-time delivery of increments and gain feedback on how the product works.
They are not faced with last-minute surprises when a team announces that software will not be delivered as expected.
Trust between customers and developers is established, and a positive culture is created in which everyone expects the project to succeed.
