Which metric is commonly used to assess the success of an epic in Lean Portfolio Management?

The metric that is most commonly used to assess the success of an epic in Lean Portfolio Management is Return on Investment (ROI). This is because ROI provides a quantifiable measure of the benefits derived from a particular investment relative to its costs. In Lean Portfolio Management, epics represent significant initiatives or investments for the organization, and understanding their financial impact is critical for assessing their success.

By evaluating ROI, organizations can ensure that they are prioritizing and funding initiatives that will deliver the most value. This metric allows stakeholders to make informed decisions about whether to continue, pivot, or discontinue an epic based on its financial performance compared to expectations. Focusing on ROI aligns with the principles of lean thinking, which emphasizes maximizing value while minimizing waste.

Other metrics, while useful in different contexts, do not provide the same direct financial insight into the effectiveness of an epic. For instance, the Net Promoter Score measures customer satisfaction and loyalty, the Capability Index assesses performance relative to capability requirements, and the Customer Effort Score evaluates how easy it is for customers to use a product or service. Although these metrics are valuable for understanding quality and customer experience, they do not specifically quantify the economic success of an investment like ROI does.
