This paper provides a brief comparison between Soft Systems Methodology (SSM) and the Work System Method (WSM) by S. Alter. The latter is a relatively recent systems approach specifically developed with the needs of the Information Systems field. It focuses on previous criticisms towards SSM and suggests how WSM might compare against them. The insights in the paper might be useful for planning and justifying the use of SSM and WSM in an Information Systems project.
