Tracking and Improving Software Quality

JC DelayPresented by

GNATdashboard

The big picture

• Track and reduce the Technical Debt on an ongoing basis

• Engage all developers from project day #1

• Raise warnings when Technical Debt is above quality thresholds

The seven deadly sins

• Duplications

• Bad distribution of complexity

• Spaghetti design

• Lack of tests & code coverage

• No enforced coding standard

• Not enough or too many comments & documentation

• Potential bugs

Code quality factors

• Maintainability

• Complexity

• Documentation

• Coding standard

• Test coverage

• Potential bug detection

Call for an orchestrator

• Compute & collect the data from each tool

• Raw, non-human friendly, output (CSV, XML, ...)

• Need to fit into a Continuous Integration system
