A data quality risk analysis is an analysis with regards to data quality.
Objective of a DQMS is that the data quality requirements are met. A risk analysis shows which situations or events could lead to these objectives not being met and which measures should be taken to reduce the risk to an acceptable level.
Purpose of a risk analysis is to determine actions that prevent data issues.
Phase | Activity |
---|---|
Plan | * Plan risk analysis |
Do | * Compose a risk analysis * Use the risk analysis |
Check | * Review/Evaluate risk analysis * Audit risk analysis |
Act | * Update risk analysis |
Characteristic | Requirement |
---|---|
Completeness | The risk analysis contains the most important situations and events. |
Effectiveness | The risk analysis leads to preventive actions that produce results. |
A risk analysis consists of the next elements:
The Fine and Kinney method shows which values should be assigned to exposure, probability and severity.
The factor exposure indicates the duration that a risk can occur. The scale varies from 0.5 to 10.
The probability or (mathematical) chance an incident will occur. The expectation is represented by ascribing a value from 0.1 to 10.
The factor severity indicates the possible damage, effects and consequences linked to a hazard. The scale reaches from 1 to 40.
The result of multiplying the parameters defines the risk-index: R = S x E x P.
Objective: Timely reporting to an external party.
Asset | Situation | Event | Measures taken | Exposure | Probability | Severity | Risk-index | Additional measures |
