2. Evaluation

2.1 Principle
  • Beckmann Model does not take into account the relative importance of benefit and risk criteria.
  • It does not integrate benefit and risk.
  • The model does not readily incorporate statistical uncertainty in input data into the analysis due to its category scoring system.
2.2 Features
  • It deals with benefits and risks separately without integrating them into a single measure.
  • The only weight in the model is driven by the 'evidence' parameters, which weigh the benefit and risk scores.
  • Other criteria within the benefit and risk scores are not weighted.

2.3 Visualisation
  • Visualisations similar to the one used in Principle of Threes may be used.

2.4 Assessability and accessibility
  • The analysis is simple.
  • It does not take into account stakeholder's value preferences.
  • It may be useful for quick initial assessments.
