It is important for standard programmes to develop a system for measuring, reviewing and demonstrating the impacts the standards are having. This is important for identifying key areas of success but also vital for identifying potential areas for improvement. It also allows a wide range of stakeholders to contribute and provides mechanisms for discussing developments across a company’s governance structure which in turn, allows it to guide strategy decisions.

Impacts are defined by ISEAL as “positive and negative long-term effects resulting from the implementation of a standards system, either directly or indirectly, intended or unintended.” These factors are all considered and measured where possible within the Monitoring, Evaluation and Learning (MEL) system (for more information please see the MEL page here).

In order to achieve the goal of demonstrating impacts, a standard systems needs to have the following:

  • A Theory of Change outlining the statement of change and main impacts with how they link to the rest of the company’s activities
  • A Monitoring, Evaluation and Learning (MEL) system providing more details on how change is measured within the programme
  • Impact Evaluations to measure and demonstrate the aims of a programme and to delve into attribution and specific challenges. These should ideally be done by an external party to ensure impartiality.

In this Impacts section of the website, we take a deeper dive into the ongoing work by MarinTrust on the above items as well as additional work being done in line with the MEL system.
