What is a systems approach?

Post 172469 by oprahgayle deleted for the following reason: Sorry, but this is a bit mixed up. If you would like to ask members for examples of successful systems approaches, the place to do that is Ask Metafilter. If you'd like to make a post about some examples of neat systems approaches with links to articles, and use the OECD white paper as support background reading, that would work (but keep personal editorial remarks out of the post, please). If you have questions, please contact us. -- taz
