In Memoriam: Remembering Peter Checkland
The System Dynamics community mourns the passing of Peter Checkland, the visionary developer of Soft Systems Methodology. Peter’s work fundamentally shaped Operational Research, and in many ways, anticipated the rise of data science and change management disciplines in the century that followed.
Our sincerest condolences go out to his family, friends, and colleagues. His legacy will continue to inspire generations. A full obituary and tributes to his remarkable achievements will follow in due course.
