Some key points

* Systems thinking is 'systemic'; relational thinking considering relationships amongst system elements, a larger concept than only 'systematic'; linear, procedural thinking.
* Western thinking is often "trapped" in overly systematic bias (OU, 2010, p. 44).
* It is [near] impossible to prevent or control change; but it may be managed (OU, 2010, p. 12).
* The change process is an iterative interaction between systemically desirable and culturally feasible (OU, 2010, p. 15-).
* Systemic inquiry is a "practice" and a "disposition", ideally accepting uncertainty and facilitating team work and social learning (OU, 2010, p. 29).
* The observer is part of a systemic inquiry (OU, 2010, p. 28).
* "Methodology .. means the logos, or logic of method" (OU, 2010, p. 39).
* A reflexive, or second order, perspective is  when something is applied to itself e.g. learning about learning (OU, 2010, p. 40).
* Reflection is the usual thinking about what we're doing. Reflexion is [?] second-order reflecting on that reflection. See "Reflection and reflexivity explained".
* Reflexion therefore considers the observer as part of the situation (OU, 2010, p. 40).
* Practice is a "relational dynamic" including a practitioner (P) applying a theory framework (F) and methods (M) in a situation (S) (OU, 2010, p. 37).
* The TU812 focus is on practitioner change (OU, 2010, p. 43); "change .. starts home" (Ison, 2010, p. 4).
* Social technologies; relationships mediated by technologies (cf. Ison, 2010, p. 7).
* "Adaptation as co-evolution": the ongoing coupling of system and environment, or rather "processes of mutually interaction" of  (cf. Ison, 2010, pp. 11-13).
