Agile Foundation guidance describes co-creation as a collaborative approach where value is created together by people who share common attitudes, values, and goals. This makes option C the correct answer. Co-creation goes beyond simply assigning work or motivating individuals to meet predefined objectives. Instead, it emphasizes collective ownership, shared understanding, and active participation by all relevant stakeholders in shaping outcomes.

In Agile environments, co-creation is rooted in the belief that the best solutions emerge when diverse perspectives work together in an open and trusting environment. Teams, customers, users, and stakeholders collaborate continuously to explore needs, generate ideas, and refine solutions. This shared mindset ensures that everyone involved is aligned on purpose and value, rather than working in isolation or following instructions without context.

Option A focuses on motivation to meet objectives, which reflects performance management rather than co-creation. While motivation is important, it does not necessarily involve shared ownership or joint value creation. Option B, agreeing ways of working, relates to establishing working agreements or team norms, which support collaboration but do not define co-creation itself. Option D, instructing the execution of tasks, represents a command-and-control approach that is contrary to Agile principles and does not encourage shared responsibility or creativity.

Agile Foundation documents emphasize that co-creation strengthens engagement, trust, and innovation. When people share attitudes, values, and goals, they are more likely to challenge assumptions constructively, learn from each other, and adapt solutions based on feedback. This approach supports Agile principles such as collaboration, customer focus, and continuous improvement. Co-creation ensures that value is not simply delivered to stakeholders but created with them, leading to better outcomes, higher satisfaction, and more sustainable Agile ways of working.
