SSE SET (in Dutch SOM SET) is an online software tool that allows multiple colleagues in one organization to simultaneously enter and consult information about issues and stakeholders, from different locations and using almost any device. SSE SET automatically generates overviews (matrix of interests, tension barometer) and reports (issue and stakeholder files). SSE SET is frequently used by companies, ministries, municipalities, and water authorities to implement their stakeholder engagement strategy. The tool creates an overview for individual projects and across projects and helps to execute them more effectively and efficiently.
