Definition

Risk Matrix: a table composed of two rows for the risks and four columns for the charac­teristics. Table 1 gives the four characteristics, defined by [6] for the Vertical Risks considered. Each risk has four characteristics as indicated in Table 1.

Table 1 – Risk characteristics

N. Characteristic Data type
1 Occurrence Real
2 Business Impact Real
3 Gravity Real
4 Risk retention Percentage (%)
  1. Occurrence: The likelihood of the risk happening [6] measured with three possible outcomes:
Low 1 the risk may occur only in exceptional circumstances or is unlikely to occur.
Medium 2 the risk may occur at some time.
High 3 the risk is expected to occur.
  1. Business Impact: consequences of a risk event [6]. It can take three values:
Minor 1 Relatively minor changes in the company processes, and/or products and services.
Moderate 2 Some minor changes in the company processes and/or products and services.
Major 3 Company processes and/or products and services are altered significantly.
  1. Gravity: impact on the ability of the company to deliver compliant products to the customer; to the internal efficiency; to damage to people, the environment, or property measured in terms of the estimated time needed to restore normal business activities. It can take five values:
Irrelevant 1 The risk has no impact on the ability to deliver compliant products to the customer; no loss of internal efficiency; no damage to people, environment, or property. The estimated recovery time is from 1 to 8 hours.
Not very relevant 2 The risk has minor impacts on the ability to deliver compliant products to the customer; marginal loss of internal efficiency; no damage to people, environment, or property. The estimated recovery time is from 2 to 5 days.
Relevant 3 May result in significant sensitive consequences on product conformity or on-time delivery; may lead to a substantial loss of internal efficiency (massive rework or 100% selections); no damage to people and the environment but possible major damage to property. The estimated recovery time is from 3 to 10 days.
Very relevant 4 Can have very important consequences on the conformity of the products or the impossibility of their delivery; no damage to persons, any marginal damage to the environment or major property damage. The estimated recovery time is from 4 to 14 days.
Serious 5 The occurrence of the risk has very important consequences on the confor­mity of products or the impossibility of delivery; involves damage to peop­le, the environment or damage important damage to property. The estimated recovery time is greater than 15 days.
  1. Risk Retention portion of the risk that the Company decides to retain (percentage) [6].
