This is the foundation page for Things I Think I Know
The definitions and explanations contained herein are intended exactly as the title suggests: they are things I think I know. They should, therefore, not be taken as authoritative: I am no Granddaddy, and neither is this web site. Many are gleaned from my collection of System Engineering manuals collected over the years, the earliest of can be dated only as “pre-1980”. Some of the manuals are variants of the Defense Systems Management College textbooks, while others are specific to individual companies or authors.
Some items in the list are a bit speculative, but have worked well for me in the past and proven portable from one project to another. A few of the items are really just stress-relievers. Apparently, I cannot help myself in that regard1.
I have, to the best of my ability, linked between definitions/explanations to mitigate the redundancy that would otherwise have eventuated. The necessary consequence of that linking is that the reader will skip around in the site in order to gain a complete picture for many of the basic concepts2.
Unlike prior (printed) editions, the web version is searchable and contains crude categorizations to group items by topic.
