Final answer:
4)Quantitative management is the management perspective centered on decision-making, cost-effectiveness, mathematical models, and computer usage.
Step-by-step explanation:
The management perspective that focuses on decision-making, cost-effectiveness, mathematical models, and the use of computers is known as Quantitative management. This approach applies quantitative techniques to managerial problems, especially in the areas of planning and operational decision-making. It leverages statistics, optimization models, information models, computer simulations, and other mathematical methods to improve an organization's ability to make solid, rational decisions.
Contrasting with other management perspectives like Operations management, Financial management, and Strategic management, which may encompass broader organizational roles and issues, Quantitative management deals with more focused, analytical methods. While the first two mentioned often involve hierarchical roles within organizations, and the latter takes a holistic approach, Quantitative management is much more data and model-driven, providing detailed analysis for decision-making processes.
