• Academic, formal
• Loosely: the number of statements that can
not be expressed as simple flow structures
(e.g. if, else, while)
28. flog vs. saikuro
• Cyclometic complexity is disputed
• Flog is not academically proven
• Flog has better Ruby understanding
29. Tracking over time
• Snapshot metrics not very useful
• Comparisons very difficult
• Tracking over time spots problems
• Use CruiseControl.rb plus metric_fu
