Mouse Hotel severity/occurrence risk matrix | Better Mouse Trap Co. samples

Sample — fictitious company. All numbers and people are invented scenario assumptions. This is draft concept paperwork; no physical testing, customer evidence, certification, filing or sign-off has occurred.

Severity increases upward; occurrence increases to the right. Bins group the illustrative 1–10 ratings in pairs. Color guides review; it never signifies accepted risk. Every item remains open.

Severity × occurrence — initial proposed risk
Severity ↓ / occurrence →	1–2	3–4	5–6	7–8	9–10
9–10	—	DF02 DF05 DF11 DF12	DF06 DF08 DF09 DF13 DF15 DF16	—	—
