Jane Searles is a UK-based Systems Practitioner and “systemic architect” known for facilitation, co-design workshops, and building shared models that help groups navigate Transformational Change in complex systems - systemspractice.org 
A recurring description of her work is that she has been developing a systemic modelling approach for decades, rooted in co-design workshops, with origins in enterprise/IT modelling practice (ICL, later Fujitsu) - metaphorum.org
She co-authored “Designing Freedom Together” with Roger Duck, a first-person case story about developing a visionary whole-system transition architecture in a UK regional transport context (2021), focusing on emergence, creativity, and design as an intrinsic aspect of change - systemspractice.org
This work has also been presented through Metaphorum (including a webinar and a recorded talk), which is useful if you want the “how they actually ran it” version rather than only the paper - metaphorum.org - youtube.com
