Paper Overview
• “Information Visualization for Agile Software Development Teams”• By: Julia Paredes, Craig Anslow & Frank Maurer
Research Questions1)What information visualization techniques are used in Agile Software
Development?2)What information visualization techniques raise awareness of
artifacts in Agile software development teams?
Information Visualization
• Information Visualization – “Use of visual representations of abstract data to amplify cognition.”[1]
• Effective visualizations should:• Quickly identify relevant information• Understand the relationships between elements of the visualization
• “Make the structure, behavior and evolution of software, such as code organization, software state and bugs, more understandable.”[1]
Information Visualization - Design
• Low Fidelity Sketches• Input Diagrams
• Both typically used to make design decision & communicate information.
Information Visualization – Design cont.• Formal Diagrams• Example UML
• Explain & Share Information• Empirical Study• 35 / 50 Developers did not use
UML• Others only used in very early
stages

Design - Example Software
•Microsoft SketchFlow•ActiveStory• Low Fidelity Sketches• Easy to produce/edit• Support gesture/touch

Design – Example Software – ActiveStory
Information Visualization - Development• Problems in source code• Areas suitable for refactoring• “restructuring the existing code without changing the external behavior”
• Continuous Integration• Automated Testing• SQA Mashup
Development Software – SQA Mashup• Tool Requirements• 1) Able to located quality hot-spots in source code• 2) Permit dynamic arrangement of information shown in the UI• 3) Provide awareness of the activities of peers• 4) Discover immediately where changes occurred, when they were made &
how made them• 5) Provide an interactive visualization of roles (developer vs. manager)• 6) Interoperate with other software engineering tools• 7) Permit independent development of UI
Development Software - CodeCity
Information Visualization - Communication• Verbal vs. Non-verbal• “Big Picture”• Standard Aspects• Dashboards
Information Visualization – Progress Tracking• Burn charts• Importance of work completed• Completion definition?• Task assigning• Estimation• MSE’s
