The best and lowest-maintenance pieces of code our team has written were carefully designed and thought out before a line of code was written. I'd say 20% of the actual work was coding, 30%/30% for design and testing and 10%/10% for requirements analysis and deployment. However, often we know that we don't know how to properly design something and we start implementing too early. The end result is sth like: 50% coding, 30% testing and the rest is squeezed into testing, deployment and requirements analysis.
