There are complex things and there are complicated things. You want to make complex things easier to understand by refining abstractions and eliminate complicated things alltogether. Constant refactoring and tabu word - intelligence - is the key here. It doesn't mean you have to reshuffle everything every week. It means spending maybe 5% - 20% of time on small things to improve code based on current knowledge. This has to be pushed by developers because semi-agile methodologies most companies use have built-in forces to move those tasks out of sprints.
