Impact

Impact is a measure of the effect of a risk on one or more project objectives if it occurs. It helps teams assess how significantly a risk event could influence cost, schedule, scope, quality, or stakeholder expectations.

Key Aspects of Impact

  • Used in Risk Assessment – Helps determine how severe a risk event would be.
  • Measured Qualitatively or Quantitatively – Can be expressed in terms of cost, time, or stakeholder impact.
  • Essential for Decision-Making – Prioritizes which risks require mitigation.
  • Works with Probability for Risk Analysis – A key factor in risk response planning.

Impact Levels in Risk Analysis

Impact LevelDescription
LowMinor effect; easily managed without major changes.
ModerateNoticeable impact; requires some adjustments to resources or schedule.
HighSignificant disruption; project success may be at risk.
CriticalMajor failure; severe impact on project objectives.

Example Scenarios

Software Development

  • Risk: A key developer resigns mid-project.
  • Impact: Moderate to High – Potential delays while onboarding a replacement.

Construction Project

  • Risk: A supplier fails to deliver materials on time.
  • Impact: High to Critical – Delays may halt construction and increase costs.

Marketing Campaign

  • Risk: A social media backlash against an ad campaign.
  • Impact: Critical – Brand reputation damage and loss of customer trust.

Why Impact Matters

  • Improves Risk Prioritization – Helps teams focus on the most severe risks.
  • Enhances Decision-Making – Supports proactive mitigation strategies.
  • Prevents Costly Surprises – Ensures teams prepare for high-impact risks.
  • Strengthens Project Resilience – Helps teams adapt effectively when issues arise.
