Modularity applies at different levels and the purpose of modularity varies according to the level. Code can be modular at one level and not modular at another.

Modularity applies at different levels and the purpose of modularity varies according to the level. Code can be modular at one level and not modular at another. Functional, domain knowledge, deployability, organisational alignment (e.g. operational support and maintainability), etc I see lots of people getting confused these days about modularity and people missing the point altogether. What is it you're after? What's most important to you? That's where you need to focus your modularity efforts.
