Start a new iRR calculation to measure the impact of your project’s activity (steps 9 - 10)
Customize the Algorithm
Steps 1 – 5: Customize the algorithm based on the type of impact you will measure
Select & Customize Metrics
Steps 6 – 9: Select and customize metrics to define how well impact is delivered
Calculate your iRR
Steps 1 – 2: Enter data and receive your iRR results in the iRR Calculations section of the site
Steps 1 - 5: Customize the Algorithm
An iRR Configuration template is a pre-built selection of Impact Themes, Areas, Sub-Categories, Key Impact Indicator, Metrics, and Metric customizations.
Note: you may edit a template, however, if you de-select a Theme, Area, or Sub-Category, the system will automatically de-select associated Metrics and lose Metric customizations. If you do this in error, simply restart your iRR Configuration and re-select your desired template to re-load that template’s default selections.
Impact Themes are broad groups of societal benefit or detriment that include all types of impact that can be measured. Within each Impact Theme are Impact Areas, and within each Impact Area are Sub-Categories of impact. Make these selections based on your project activity’s type of impact.
Impact Themes include:
Impact Areas are filtered based on your previous Impact Theme selection. Impact Areas are groups of related sets of Sub-Categories of impact. For example, the Housing and Shelter Impact Area includes Sub-Categories such as Affordable Housing and Workforce Housing. The Energy Impact Area includes Sub-Categories such as Energy Production, Consumption, and Conservation.
Note: There are approximately 50 Impact Areas across the 5 Impact Themes.
Impact Area Sub-Categories are filtered based on your previous Impact Area selection. An Impact Area Sub-Category describes the type of impact to be measured, and this selection filters impact delivery methods (Key Impact Indicators) and Impact Metrics, which you will select in the following steps.
Note: There are approximately 150 Sub-Categories across the 50 Impact Areas.
A Key Impact Indicator (KII) is a unit of measure through which your activity delivers impact. For example, megawatt hours generated by a solar power project, acres of land sustainably farmed, patients treated at a hospital, or square feet developed for a sustainable real estate project.
The number of KII units represents the quantity or magnitude of your activity's impact – the higher the number, the more impact that is delivered. The unit is a clearly defined and straightforward metric directly tied to the activity’s impact goals.
Note: There are approximately 100 Key Impact Indicators across the 150 Sub-Categories.
Steps 6 - 9: Select & Customize Metrics
Impact Metrics make up a set of quantitative and qualitative measures that define how well impact is delivered by your project's activity. Selecting and customizing Impact Metrics creates a quality rating system for your activity (ranging from low quality impact to high quality impact). Users typically select between 10 and 30 Impact Metrics.
Note: If you wish to expand the list of possible metrics, return to steps 1 - 3 and select additional Themes, Areas, and/or Sub-Categories of impact.
Assign a weighting to each metric based on how important that metric is to your scoring. Very important metrics receive higher weights relative to metrics of less importance. For example, if you have 4 metrics total – 2 highly important metrics and 2 moderately important metrics – you might assign weights of 30%, 30%, 20%, and 20% respectively. This weighting sets a percentage of possible points available to each metric, and the total of all metric weights must sum to 100%.
Note: How an activity performs across these metrics indicates its quality of impact, and significantly affects the activity’s iRR results.
Each metric requires a rating scale to describe how well an activity scores for that metric. A score range is similar to a performance evaluation, where each metric is defined by stages along a range of performance. The bottom of the range describes poor performance (low impact), where an activity will receive few or no possible points. The top of the range describes high performance (high impact), which is associated with a high rate of possible points.
For example, if an activity reduces poverty in an area by 1%, and you defined the bottom of the score range as “2% or less”, then the activity would score poorly. Alternatively, if an activity reduces poverty by 6%, and you defined the top of the score range as “5% or more”, then the activity would score well.
Here are you defining these performance levels along a six-stage score range.
The system provides default score ranges for metrics, which you may customize in this step.
Each stage along the metric rating scale (the performance levels you defined in the previous step) is associated with a rate of possible points to award. For example, if an activity performs at the bottom of the range (poor performance or low impact) for a metric, it defaults to earning 0% of the possible points. The top of the range (high performance or high impact) defaults to earning 100% of the possible points.
Users generally use iRR to measure positive impact with metric score rates of 100%, 80%, 60%, 40%, 20% and 0%:
However, you may adjust these rates for each metric. For example, you may want to reward high (top range) performance for a metric with bonus points and set a score rate above 100% (e.g. 120%).
Or, you may want to account for negative impact and assign a negative score rate, such as -100%, for poor (bottom range) performance. By setting bottom range performance to a -100% score rate, for example, a metric performing at that level will subtract 100% of its possible points from the total points of all metrics.
This is the final step in customizing how the iRR system will score your Impact Metrics.
When you enter data in the iRR Calculations section, each metric will be awarded points based on three things:
The metric’s possible points, determined by the weighting you set in step 6
The metric’s performance level, for which you defined score ranges in step 7
The score rate for each performance level, which you set in step 8
