The documentation distinguishes clearly between mission/purpose, objectives, strategy, and tactics. A mission statement declares what business the organisation is in and what it is intending to achieve—it is the overarching purpose that provides direction and is meaningful to stakeholders such as employees and customers. In contrast, objectives are specific goals that can be measured, while strategy and tactics describe approaches and detailed means of execution.

Option C is the best “purpose/mission style” statement because it communicates a broad intent and aspiration in plain language that can be understood by both internal and external audiences. It expresses what the organisation aims to be known for and the overall value proposition it wants to deliver, which aligns with the role of a mission in providing clarity and direction.

Option A is a measurable target (an objective) tied to SLA performance, not a purpose statement. Option B describes an internal method/approach (closer to tactics or operational improvement activity) rather than the organisation’s reason for existence. Option D is a specific policy or initiative (sustainability sourcing), which can support purpose, but it is too narrow to represent the overall company mission.
