Final answer:
C) Brainstorming
SWOT analysis, Scenario planning, Brainstorming, and Competitive intelligence are all valid techniques for improving decision-making in strategic planning. However, the question, as it stands, does not contain an option that would qualify as not being a means of improving decision-making.
Step-by-step explanation:
The question asks which of the listed options is not a means of improving decision-making in the formulation and implementation of strategic plans.
The options presented include SWOT analysis, Scenario planning, Brainstorming, and Competitive intelligence.
Each of these options, except for one that is not mentioned in the question, can be very effective in strategic planning processes.
For example, SWOT analysis is instrumental in identifying the Strengths, Weaknesses, Opportunities, and Threats of a company.
Scenario planning allows organizations to envisage different future scenarios and prepare for them. Brainstorming opens up the floor to a wide array of ideas, encouraging creative solutions.
Lastly, Competitive intelligence involves gathering and analyzing information about competitors, which can significantly influence strategic decisions.
However, based on the context given in the question and the reference to other subjects, none of these options is incorrect as a technique to improve decision-making in strategic plan development.
It is possible that there might be confusion against another question that was not directly related to this one.
