Resumo
This manuscript presents an account of the Sociotechnical Systems Safety
Analysis Group’s (GASSST) application of Soft Systems Methodology (SSM) to a
complex safety issue at the Nuclear and Energy Research Institute in São Paulo, Brazil
(IPEN-CNEN/SP). Drawing from both theoretical foundations, based on the
documentation produced by Peter Checkland and other researchers, and practical
experiences, the study explores the SSM approach in addressing challenges that involved
technical and human factors. The principal results include the identification of key
stakeholder perspectives, the development of a rich picture to capture the complexity of
the problem, and the initiation of potential solutions. However, the full application of
SSM was curtailed due to proactive interventions by the facility staff, which resolved the
initial problem before all SSM steps could be completed. The process was further
interrupted by the COVID-19 pandemic-induced hiatus, during which facility staff were
absent for 1 year and 10 months. The study concludes that timely application of SSM and
the expertise of facilitators are critical for navigating complex safety issues effectively.
This experience underscores the need for experienced practitioners and a more prompt
application of SSM to fully leverage its potential in addressing organizational challenges.
GASSST's reflections and documented experiences contribute valuable insights to the
ongoing discourse on SSM's practical relevance in similar contexts.
