Integration Readiness Assessment
These fifteen questions cover the five dimensions that decide whether an integration will work on a live site. The assessment scores each dimension separately. Four strong scores cannot offset one critical weakness, because that pattern is common in projects that fail.

UNIT 07These are the sources for the reasoning on this page. We mark standards that you must pay to read. Where a free document covers the same subject better, we list it first.
- NIST SP 800-82 Rev. 3NISTGuide to Operational Technology Security. It is free, several hundred pages long and the most useful single document in this field. Our segmentation planner follows its model of zones and conduits.
- ISA-95Paid standardISAThe standard for integrating enterprise and control systems, and the source of the Purdue level model. It gives the official definitions of Levels 0 to 4.
- ISA/IEC 62443Paid standardISAThe series of security standards for industrial automation. Customers and insurers usually cite it when they ask how your operational technology (OT) is secured.
- ISO 42001 explainedISOISO's free summary. Read this first to decide whether certification is relevant to you before you buy the standard.

Each of these tools is a short version of a conversation with one of our engineers. If your result raised a question you want to discuss, book a scoping call and bring your result with you.
