Which significant bodies have made a solid case for systems thinking?

A friend of a friend is facing some push-back on the status of systems thinking as compared e.g. to managemen, psychology, other organisational thinking. This could potentially have impacts on her immediate career prospects.

So we are looking to create a collection of high profile organizations who have stated that we need more systems/holistic/joined-up/integrated/etc. thinkers to solve world problems.

Ellen Lewis contributed three stonking examples:

1. 2017, UN Chief Executives’ Board for Coordination described systems thinking as a “key way of working” and an essential “leadership characteristic” needed to respond to the “interconnectedness and indivisibility” of the United Nations’ 2030 Agenda for Sustainable Development and its 17 Sustainable Development Goals (SDGs).

2. In 2018, the Governance Directorship of the OECD declared that “the time for piecemeal solutions in the public sector is over” and they recommended the use of systems thinking to instigate innovative solutions to cross-cutting and complex issues.

3. The International Council for Science (ICSU), which reports to the UN, has released a report saying that a massive shift towards systems thinking for coordinating the SDGs is needed. This report is more systems-focused than any I have seen before, and ICSU are putting their money where their mouths are: they are integrating themselves with the Social Science equivalent body, to have a more systemic approach themselves.

And I came up with (clearly linked to (2) above):
4. OECD-OPSI (Observatory of Public Sector Innovation) said this strongly:

5. Paulibe Roberts (who has featured here more than once as www.systemspractitioner.com) adds the World Health Organisation: www.who.int/alliance-hpsr/resources/9789241563895/en/

Any more for any more?
