A repeatable method for deciding what your information and systems are worth, with the reasoning recorded so the result can be defended a year later.
 
Most organizations assess system value once, in a workshop, and end up with a spreadsheet of numbers nobody can explain six months on. The SRMBOK Information and System Value Assessment gives you a complete workbook and a fully worked example, so you get consistent, defensible results across a whole system portfolio without building the method from scratch.
 
Each system is assessed for confidentiality, integrity and availability against eight consequence categories with calibrated Business Impact Levels. The workbook records the resulting impact level, sensitivity label, caveats and, critically, the reasoning behind each judgement.
 
What's included
The complete assessment workbook:
Information and system ownership and service elements
Eight consequence categories with 0 to 5 impact criteria
Confidentiality, integrity and availability assessment
Business Impact Level and sensitivity classification
ICT lifecycle, hosting, backup, disaster recovery and access management
Built-in formulas, lookups and rating logic
Glossary, FAQ, and PSPF, NIST and commercial classification crosswalks
 
The fully worked Riverina Water Corporation example
Five systems assessed end to end: SCADA, customer information, laboratory, public-facing and asset management. It shows the judgement behind the numbers: why the highest credible consequence governs rather than the average, why zero is a legitimate rating, how external controls affect system value, and why a highly valuable system does not necessarily hold secret information. Use it as a reference, a training aid for new analysts, or a starting point for your own assessments.
 
Built to be adapted
Consequence criteria, sensitivity labels and information categories can be recalibrated to your own risk framework and policies. Once configured, the same method applies consistently across the portfolio.
