Is it typically in the defining the business phase where a written set of core values is developed?

During the defining the business phase, it is indeed common practice for organizations to establish a written set of core values. This phase is critical as it shapes the foundation of the organization, guiding its mission, culture, and decision-making processes. Establishing core values helps ensure that everyone within the organization understands the principles and ethics that drive its operations and interactions.

Core values articulate what is important to the organization and reflect its aspirations and priorities. By developing these values at the outset, organizations set a clear direction and create a cohesive environment where employees can align their actions with the overarching goals of the business.

In contrast, options that suggest it happens only for non-profits or solely in the implementation phase do not align with the typical practices observed in business. Core values are essential for all types of organizations and should be defined early in the business's development to ensure that they are integrated into all future planning and operations.
