Why Small Features Take Months on a Legacy Codebase
Why does a small feature take months?
Twelve modules move with the change, and coordination overhead is 40 hours. A 40-hour feature becomes 464 hours, which is 11.6 weeks of one engineer.
Where do the 464 hours come from?
The multiplier is 11.60. Hours are 40 times 11.60.
What does that feature cost?
At $150 an hour the feature costs $69,600. Vacuum cost is $6,000. At 24 features a year the annual figure is $1,526,400.
Which two inputs should I set first?
Set Connascence Degree to 12 and Vacuum Effort to 40. Keep the other inputs from the worked example.
