What is your ratio Bug fixing vs Enhancements? [closed]

Question

In the spirit of this question I wanted to have a sense of what is the proportion of time split between fixing bugs and implementing new features. If possible try to give an estimate for the product as a whole as opposed to individual developer stats and try to make an average over the course of a typical year. Do provide a general descriptive of the product/project to allow comparison. Specifically :

• Maturity of project
• Is it still actively developed or strictly in maintenance ?
• Size estimate of the product/project
• Size of team developing it (all inclusive)
• What is your team score on the Joel test.

Ex :

• approx 80% time spent bug fixes 20% new stuff
• Mature software (20 years old)
• Actively developed
• 1.5M Line of Text, approx 700k - 900k LOC
• 12-15 actively coding in it.
• we got 5/12 for sure, some would say 7/12.

Answer 1

I would estimate: New features 70%, Bugs 10%, Technical debt (refactoring etc.) 20%

• Maturity: 2 years
• Actively developed
• Team size: 8
• LOC: 50k-100k
• Joel Test: 9/12

You didn't ask for technology stack but if you are interested it's Ruby on Rails
