How computing systems facilitate planning: what are the key advantages that computers bring to managerial planning under uncertainty?

Introduction / Context:
Managerial planning frequently involves uncertainty, multiple scenarios, and complex trade-offs. Computing systems transform planning by enabling rapid analysis, iterative modeling, and wide scenario coverage. The question asks which advantages computers provide in this context.

Given Data / Assumptions:

• Managers need speed, breadth of scenarios, and computational power.
• Planning models can be complex (optimization, simulation, forecasting).
• Timeliness of information is critical to decision quality.

Concept / Approach:
Computers allow planners to enumerate and test many “what-if” possibilities, apply sophisticated algorithms to complex problems, and deliver results quickly for decision meetings. These benefits are complementary: breadth (many possibilities), depth (complex models), and timeliness (quick answers). Hence, the correct response is that all listed advantages apply.

Step-by-Step Solution:

Verification / Alternative check:
ERP, BI, and analytics platforms demonstrate these benefits daily: planners iterate quickly across scenarios, solve complex models, and obtain timely insights.

Why Other Options Are Wrong:
Each single benefit is accurate but incomplete; only the inclusive option conveys the full value proposition.

Common Pitfalls:
Overreliance on speed without validating data; ignoring model assumptions when exploring many scenarios.

Final Answer:
All of the above
