User Story Limitation

User stories can sometimes miss important details or fail to fully capture the scope of requirements.

Incremental Development Testing

In incremental development, testing is automated and continuous, ensuring that all tests pass before development can proceed.

Test-First Development (XP)

Tests are written before the code, guiding the development process and ensuring that the code meets the requirements.

Customer Feedback in Incremental Development

Customers receive regular updates and feedback on the product's progress, enabling them to adjust requirements and ensure alignment with their needs.

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.
