What measures a portfolio's progress in Business Agility?

Measuring a portfolio's progress in Business Agility involves evaluating how effectively the portfolio can adapt to changes in the business environment and how quickly it can respond to customer needs. The "Measure and grow" approach is particularly significant in this context because it emphasizes the importance of metrics and continuous improvement. This method encourages organizations to establish clear metrics that can track progress, enabling them to identify areas of strength and opportunities for development.

The concept is rooted in the principle that to embrace business agility, organizations must not only implement Agile practices but also assess the effectiveness of these practices over time. By measuring various aspects such as value delivery, customer satisfaction, and team performance, organizations can make informed decisions to adjust their strategies, improve processes, and foster an adaptive culture.

In contrast, the other options focus on various elements that contribute to a successful Agile environment, such as promoting an innovative culture or practicing customer-centric design. While these are essential for overall agility, they do not specifically encapsulate the process of measuring progress in business agility like "Measure and grow" does. Therefore, choosing this answer accurately reflects the importance of quantifiable assessment in achieving and sustaining business agility.
