I came across an interesting piece about systems thinking in the realm of accessibility and share it with you here: Full article: Systems thinking for assistive technology: a commentary on the GREAT summit (tandfonline.com). It ties in with something I stress to people with whom I work and others: accessibility cannot be viewed just as an add-on, a checklist, an onerous set of requirements. It has to be baked into our designs, specifications, and activities, so we don’t think about it; it is just there. By being "just there” our designs, specifications, and activities will react to advances in the state of the art.
