Step 5: Assess scale and value

Key Takeaways

  1. Based on your IMP analysis, you must evaluate the value of impact from -5 to +5.

  2. The scale is assessed from 1 to 5, following an exponential rate. It should be evaluated by looking at the breadth, depth and persistence of the impact.

Assessing value and scale

Once you have written your analysis, you must attribute a value and scale to the impact described.

For this, you should base yourself on the Logic Model and IMP evaluation you undertook, and then think about two questions:

1. How positive or negative is this impact?

2. What is the scale of this impact?

👉Before reading this article, we recommend that you first go through Step 1: Understand Impact.

1. How to rate the value

Is the impact that you described negative or very positive for the environment or society? And to what extent?

The scale goes from -5 (very negative) to +5 (very positive).

How can a company impact the planet and/or society?

  • Through its processes and practices

Examples: industrial pollution or decent job creation

  • Through its products and services

Examples: health issues or increased mobility

  • Through its influence on society

Examples: disruptive technology or market transformation

Can the same issue have a very different impact on distinct groups of people?


  • Some people might benefit while others will not.
  • Some groups are more sensitive to impact than others (i.e., children, refugees, etc.)

Can the same issue have a very different impact whether it is short or long term?


  • Some issues might bring short-term positive impacts but create more problems in the long run.
  • Some issues might seem negative today but are in fact very positive for the future.

2. How to rate the scale

Rate the scale of the company’s impact from very small to very large. Will the impact that you described have an influence on a large group of people? Will it last over generations? Take into consideration both the breadth, depth, and persistence of the impact when rating the scale of the impact.

The scale goes from 1 to 5, 1 being a very small impact and 5 being a very large impact.

1/ Take into account the breadth of the impact

  • Is the impact local, national, or global?
  • How many people are concerned? Thousands? Millions? Billions?

As a rule of thumb, if it affects at least 1 million people it is considered significant. Although, please bear in mind that this is not always the case, as at times, it could be considered unfair to expect an impact to touch that many lives. Thus, this is flexible.

2/ Take into account the depth of the impact

  • Is the life of people concerned deeply affected, or are they just marginally impacted by the issue?
  • Are the changes brought by the issue profoundly changing society or the planet?

3/ Take into account the persistence of the impact

  • How long would the impact described last for? Months? Years? Decades?
  • How reversible is the impact described in the Impact Analysis? Can it be easily stopped/extended?

3. How to rate the quality

Impaakt is about grouping like-minded people, who create high-quality and critical content. There are robust processes in place to ensure quality, so as a writer, you should always aim for 5 stars! As a rater, your opinion matters!

Keep these criteria in mind when rating analyses, and writing your own:

1 = Very Poor

This analysis is none of the following criteria: insightful, creative, informative, clever.

2 = Poor

This analysis shows some of the following criteria: insightful, creative, informative, clever.

3 = Average

This analysis shows many of the following criteria: insightful, creative, informative, clever.

4 = Very Good

This analysis includes the majority of the following criteria: insightful, creative, informative, clever

5 = Outstanding

This analysis includes all and more of the following criteria: insightful, creative, informative, clever.

Why is it important to use equivalents and proxies?

Using equivalents and proxies helps readers to effectively gauge the scale and value of the impact analysis. Even more, analyses written within the same genre can more easily be compared.


I want to report British American Tobacco’s impact and human death, but this data is not reported by the company or an independent source. Don’t worry. As a topic like this is relevant to the core business of the company, we allow contributors to use approximations. In this specific example, analysts have previously used the number of deaths linked to tobacco consumption and the market share of the company in this sector to calculate the estimated number of deaths the company is responsible for.

Here are a few resources that could be useful for equivalencies:
