ISEAL's Kristin Komives presents a webinar in the Sustainability Standards Essentials series on key concepts in the development of a Theory of Change (ToC) for a standard system. This webinar broadly covers the key elements of a ToC and three important applications: M&E, strategic planning and communications. In presenting this, Kristin draws on lessons learned from standards systems about how to successfully engage stakeholders in the process of developing a ToC. Kristin illustrates all the core concepts with examples from ISEAL members’ ToC. This webinar is useful for any organisation wanting to learn more about what makes a robust M&E system, a precondition for a credible standards system.
