| - | An **Argument** is a rule that provides the bridge between what we know or are assuming (sub-claims, evidence) and the claim we are investigating. The argument used depends on the type, trustworthiness and extent of available evidence and the nature of the claim. Note that "argument" is an overloaded word and we are using with a specific meaning here. | + | An **Argument** represents logical propositions intended to support a [[ddsf:public:guidebook:06_append:glossary:c:claim]] through reasoning or logic that links [[ddsf:public:guidebook:06_append:glossary:e:evidence]] to a claim. Arguments define the relationships directly linking each claim and/or [[ddsf:public:guidebook:06_append:glossary:s:subclaim|sub-claims]], and piece of evidence, used by an argument to the claims immediately supported by the argument. An argument is the explanation of how the evidence can be interpreted as supporting a claim or sub-claim. |
| - | Source: [[https://claimsargumentsevidence.org/notations/claims-arguments-evidence-cae/]] | + | Arguments can also include any unusual events or conditions that are within the context of the claim. The argument can contain considerations of potential causes of failure and appropriate corrective actions if failure occurs. Hence, an argument may include conditions, assumptions, and judgments about the system, its use, and its operational environment, threats, and likelihood of occurrence, for which the claims and evidence are being marshaled as part of an overall assurance case. |
