Reach, Impact, and Confidence

Reach

Reach is an indication of how many users are affected by the defect.

• To determine Reach, consider how many customers will be impacted by the defect within a defined time period
  • Consider a time period of 3 months by default as this aligns with a quarterly cadence
• Reach options
  • Extensive / Widespread
  • Significant / Large
  • Moderate / Limited
  • Minor / Localized
  • Isolated

Impact

Impact is a measure of the consequence (like severity) of the defect.

Impact should not be confused with an impact radius (Reach).

• Impact options
  • Significant Adverse Consequences
  • Disruptive, clinic-level impacts
  • Disruptive, provider-level impacts
  • [Some impact, but] has workaround
  • Minor annoyance, no real impact

Confidence

Considering available data and information how confident are you of the Reach and Impact selections?

• Confidence options:
  • High [the default value for the CDR Model]
    • Ample data, good clarity on who is impacted and the extent/reach of the defect
  • Medium
    • Clear understanding of the domain, a fairly good understanding of reach and impact
  • Low
    • Highly subjective, lack of data with significant obstacles/impediments to overcome for improved confidence
