Information Visualization as an aid to Agile Software Development

Explore the use of information visualization to enhance agile software development teams' awareness and decision-making. Learn about techniques like low-fidelity sketches, formal diagrams, and design tools, such as ActiveStory. Understand how visualization aids in identifying code issues, tracking progress, and communication within the team. Discover software tools like CodeCity and SQA Mashup that support agile development requirements. Discuss the implications of these visualization techniques and overcome adoption barriers in agile practices.

  1. Information Visualizationas an aid toAgile Software Development By: Andrew J. Armstrong

  2. Agile Software Development Overview[4] • Manifesto • Individuals and interactions over processes and tools • Working software over comprehensive documentation • Customer collaboration over contract negotiation • Responding to change over following a plan

  3. Agile Software Development Overview cont. http://images.vertex42.com/ExcelTemplates/excel-gantt-chart-MF_large.gif http://cdn.ttgtmedia.com/WhatIs/images/pert_chart.jpg

  4. Paper Overview • “Information Visualization for Agile Software Development Teams” • By: Julia Paredes, Craig Anslow & Frank Maurer Research Questions • What information visualization techniques are used in Agile Software Development? • What information visualization techniques raise awareness of artifacts in Agile software development teams?

  5. 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]

  6. Information Visualization - Design • Low Fidelity Sketches • Input Diagrams • Both typically used to make design decision & communicate information.

  7. 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 http://www.uml-diagrams.org/examples/class-diagram-example-hasp-licensing-domain.png

  8. Design - Example Software • Microsoft SketchFlow • ActiveStory • Low Fidelity Sketches • Easy to produce/edit • Support gesture/touch http://blogs.msdn.com/cfs-filesystemfile.ashx/__key/communityserver-blogs-components-weblogfiles/00-00-01-06-46-metablogapi/7041.donate_5F00_thumb_5F00_1A04D12A.png

  9. Design – Example Software – ActiveStory

  10. 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

  11. 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

  12. Development Software - CodeCity

  13. Information Visualization - Communication • Verbal vs. Non-verbal • “Big Picture” • Standard Aspects • Dashboards

  14. Information Visualization – Progress Tracking • Burn charts • Importance of work completed • Completion definition? • Task assigning • Estimation • MSE’s https://www.atlassian.com/wac/software/jira/agile/tourBlocks/0/screenshotTourSection/01/imageBinary/jiraagile-02_whyja_1_flexibleplanning.png

  15. Discussion & Conclusions • Design • Sketches • ActiveStory • Development • Understanding Code • Physical Objects • Communication • Information Radiators • Dashboards • Progress Tracking • Taskboards

  16. Discussion & Conclusions cont. • Implications • Barriers to adoption of technologies
