What are the methodologies for impact assessment?


  • Scoping (e.g., checklists)
  • For qualitative analysis (e.g., focus groups)
  • For quantitative analysis (e.g., life-cycle assessment, material flow accounting, modelling)
  • Aggregation and comparison of options (e.g., cost–benefit analysis)
  • Analysing coherence (e.g., Gender IA)

What is impact analysis methodology?

The impact assessment methodology for planned activities takes into consideration impact magnitude and receptor sensitivity. A matrix is also used to derive impact significance, for pre- and post-mitigation conditions. The concept of likelihood is included in the methodology for unplanned events.

What is impact analysis?

In practice, impact analysis is a detailed study of business activities, dependencies, and infrastructure. It reveals how critical products and services are delivered and examines the potential impact of a disruptive event over time.
