Answer: False
Explanation: The opposite of the stated is true. An effective operations management effort must have a mission so it knows where it is going (a mission is the purpose for which an organization exists) and a strategy so it knows how to get there (an organization's strategy are its action plans at different areas/levels that are laid down for achieving the organization's mission).
While missions can be achieved by three conceptual ways (differentiation, cost leadership and response), an organization's strategy for operations may include time and quality based strategies, outsourcing, supply chain management, integration etc.
