Final answer:
The statement that once an effective strategy is designed, modifications are rarely required is false. Strategies must continually adapt to the dynamic nature of both internal and external factors, as evidenced across various disciplines including business and physics.
Step-by-step explanation:
False, once an effective strategy is designed, modifications are often required. Strategies must be adaptive to changes in the market, technology, competitors, and other external factors. Moreover, internal changes such as shifts in company goals or resources also necessitate strategy tweaks.
In the context of social and economic changes caused by events like the market revolution, it's evident that strategies must evolve. The market revolution indeed brought significant changes, emphasizing the dynamic nature of business and social environments. Similarly, in the case of displacement or the position vs time graph of an object that is speeding up, the principles of physics demonstrate that such simplifications are not always consistent with the complexities of real-world scenarios. Lastly, in terms of political strategies, majority rule can indeed fail to produce a preferred outcome, as observed in scenarios with multiple choices, showcasing the need for adaptability in strategy.
