Scoring Guidance

Stakeholders score each IRO on a scale of 1 to 5. The dimensions scored depend on the type of IRO. This page explains what each dimension means and how to apply the scale consistently.

Positive impacts

Positive impacts are scored on three dimensions:

Dimension	1	2	3	4	5
Scale	Negligible benefit	Minor benefit	Moderate benefit	Significant benefit	Transformative benefit
Scope	Affects very few	Affects a small group	Affects a moderate number	Affects a large group	Affects a very large number
Likelihood	Very unlikely	Unlikely	Possible	Likely	Near certain

Negative impacts

Negative impacts are scored on four dimensions:

Dimension	1	2	3	4	5
Scale	Negligible harm	Minor harm	Moderate harm	Significant harm	Severe harm
Scope	Affects very few	Affects a small group	Affects a moderate number	Affects a large group	Affects a very large number
Irremediability	Fully reversible	Mostly reversible	Partially reversible	Mostly irreversible	Permanent/irreversible
Likelihood	Very unlikely	Unlikely	Possible	Likely	Near certain

Financial opportunities

Financial opportunities are scored on two dimensions:

Dimension	1	2	3	4	5
Magnitude	Negligible financial effect	Minor effect	Moderate effect	Significant effect	Very large effect
Likelihood	Very unlikely	Unlikely	Possible	Likely	Near certain

Financial risks

Financial risks are scored on two dimensions:

Dimension	1	2	3	4	5
Magnitude	Negligible financial effect	Minor effect	Moderate effect	Significant effect	Very large effect
Likelihood	Very unlikely	Unlikely	Possible	Likely	Near certain

tip

Encourage stakeholders to use the full range of the scale. Scores clustered at the top or bottom of the range make it harder to distinguish between material and non-material topics.
