 The basic idea of agile, which everybody has in common agrees to, of doing small steps like a week or two or something like that, that's fine, but they fail to do something I described as early as my 76 book, that you need to measure, get measurable feedback about whether you're delivering customer results and you need to use that feedback to alter things if you're not going in the right direction. In other words, feedback and learning. The agile we know today is more like produce some code to do this functionality and accumulate it, but there's no clear idea that we're trying to improve security by 50% and we need to, you know, 1% at a time build up from 50% security to 90% security. There's no such notion in what people do. So in other words, what the agile we have today is largely we have organizing programmers to program and code. It is not a way of building systems that successfully and regularly deliver extremely good results to their customers. And again, I refer to the Standish reports, which is based on 50,000 projects, which clearly say that agile fails only slightly less than waterfall and it has done so for decades. So, you know, our whole community is failing whether they use agile or not.
