I think there's a great deal of discipline used by those who do large-scale Ada development. I also think XP encourages a lot of reuse of software. (Indeed, the "once and only once" mantra could be considered a recommendation that software be maximally reused.) I think Ada is a programming language with a philosophy of programmers spending a lot of forethought and planning up front to get a high-quality robust result. I think XP is a programming philosophy where you spend a minimum of forethought and planning up front (for various reasons having to do with the nature of the requirements) and hence works well in a language where you don't need to do a lot of planning up front to get an initial result. The rest of XP is basically how to get a high-quality result in spite of not planning very far ahead. Personally, I like both Ada and Smalltalk. I wouldn't use them for the same thing, tho. -- Darren New San Diego, CA, USA (PST). Cryptokeys on demand. The 90/10 rule of toothpaste: the last 10% of the tube lasts as long as the first 90%.
