Key Points Decision-Making

Decision-making is the process of making choices by identifying a decision, gathering information, and assessing alternative resolutions. Using a step-by-step decision-making process can help you make more deliberate, thoughtful decisions by organizing relevant information and defining alternatives.

Important Points Henry Mintzberg proposed that there are 4 modes through which managers make decisions: 

Entrepreneurial mode - 

• Strategy is made by one powerful individual who has entrepreneurial competencies like innovation and risk-taking. 
• The focus is on opportunities. 

Adaptive mode - 

• The adaptive mode is where managers create reactive solutions to existing problems, rather than a proactive search for new opportunities.
• This s a fragmented approach to strategic decision-making.
• Because of the lack of directed focused development, there is generally a lack of clarity and consensus on strategic goals. 

Planning mode - 

• The planning mode of strategic decision-making is characterized by the systematic gathering of relevant information for situation analysis
• The generation of feasible alternative strategies, and the rational selection of the most appropriate strategy. 

 Logical Incrementalism mode- 

• Logical Incrementalism is a fourth decision-making mode was added  to Mintzberg’s modes by James Bryan Quinn (1980).
• This approach appears to be useful when the environment is changing rapidly, or resources must be developed before committing the entire corporation to a specific strategy.

Hence, the correct answer is (A) and (C) only.
