Tailoring Is an Engineering Decision, Not Administrative Paperwork

MIL STD 461G is intentionally written to require engineering judgment. It assumes that test requirements will be tailored based on the actual installation environment, the intended platform, the power architecture, and the cable configuration. Applying every available test without discrimination does not increase rigor. It increases risk. Poor tailoring leads to failures irrelevant to real-world operation, drives unnecessary test scope, and inflates cost and schedule without improving confidence. Results generated under those conditions often lack technical meaning.

Proper tailoring aligns test methods with credible operational threats and realistic coupling mechanisms. It ensures that failures indicate fundamental design weaknesses rather than artificial test conditions. Laboratories that skip or minimize this step are executing procedures. They are not performing engineering.
