Technical Report on Raster field test at a Water Board

Risk assessment of unavailability of telecommunication services is an important part of an organisation’s business continuity management. We developed the Raster method to enable organisations to assess their telecommunication service unavailability risks. To validate Raster in practice we conducted two field tests in which the Raster method was applied at a typical target organisation. This document reports on the second field test, at a Water Board in the Netherlands. This report describes the research goals, method, and results of this field test, and compares the results to those of the first field test. This field test reconfirms the usefulness of the Raster method, and adds some new lessons-learned.
