Group Decision Making

 The purpose of group decision making is to form a consensus on how to move forward on a topic (Hsieh et al., 2020). There are several methods that can be used by groups to make a decision. For this discussion post, we are tasked with defining two different group decision-making methods. Once defined, the two selected methods will be compared and contrasted.

Method 1: Brainstorming

            Brainstorming is one of the more well known method of decision making (Bang & Frith, 2017). This method is typically conducted with a group of people bouncing ideas off of each other to produce a potential solution to a problem. This method allows for free-flowing discussions and the whole group are able to share their input towards a solution.

Method 2: Weighted Scoring

            Weighted Scoring is a method of group-decision making where there are multiple possible solutions determined (Bang & Frith, 2017). The different ideas are weighed based on riskiness, cost, and how much of a value the solution brings. The ideas are given a numerical score based on these variables. The solution with the most ideal score is selected. This is a common decision making for businesses to determine the best solutions for business processes.

Compare and Contrast

            The first similarity between brainstorming and weighted scoring is that the decisions are made in a group. This is obvious, but this is one of the main advantages of this type of a decision making. An individual’s bias is reduced when the decision making is a consensus rather than a unilateral decision (Bang & Frith, 2017). The second similarity is that each member of the group can input their ideas to contribute to the decision.

            The main difference is how the decisions are made. Brainstorming may conclude in a solution, but it is used to produce ideas to solve a problem. A single solution may not be determined, but multiple potential solutions could be thought of. Weighted scoring has a list of solutions that the group must determine which solution is the most effective. The conclusion of weighted scoring will produce one solution per problem.

Forecasting and Innovation

  Infamous Prediction That Came True             The future is almost never certain. However, there are some methods that can be used in order to predict what the future may hold (Chermack et al., 2001) . Some of the predictions that were made in the past have come to fruition. One example of these predictions are the 15 advancements in technology that Bill Gate’s provided in 1999 (Gates, 1999) . While not the exact predictions, all 15 became commonplace in the current era. I won’t cover all of the predictions, but one of the most infamous can relate to his predictions on digital marketing. Summarization             The ninth prediction that Bill Gate made was "Devices will have smart advertising. They will know your purchasing trends, and will display advertisements that are tailored toward your preferences." (Gates, 1999) . Ever talk to someone about a certain produ...

Scenario Planning over Forecasting

Image
  There are moments in history where traditional forecasting methods have failed (Ademmer & Boysen-Hogrefe, 2022) . While it is not possible to completely what will occur in the future. Organizations can attempt to predict what may occur based on historical precedent and accumulated data (Klimberg et al., 2010) . While some errors do not have severe impacts, there are times in history where forecasting errors can have consequences. In this individual project, one of these forecasting errors will be discussed. Following the summary will be a discussion on how scenario-planning supports futuring and innovation. The forces that support scenario-planning will be identified as well. The project will conclude with the student considering how they will use scenario-planning for future innovation efforts. Forecast Failure: The Great Recession One of the more recent forecast errors that resulted in far reaching consequences was the economic crisis of 2007 – 2009 (Gadea Rivas &...

Planning

  When attempting to plan for the future, there are a few methods that can be used to make these plans. Organizations planning for future events in paramount to be able to successfully grow and expand (McKenzie & Sansone, 2019) . In this discussion post, we will compare two different methods of planning. The first method is scenario planning and the second is traditional planning. Scenario Planning             The first method of future prediction is scenario planning. Scenario planning is a method of prediction that provides a flexible long-term plan (Chermack et al., 2001) . The planning often includes a mix of qualitative and quantitative perspectives to make predictions (Chermack et al., 2001) . The organization will observe both what is motivating the organization such as the economy or evolving technologies. Then the organization will identify uncertainties with these motivations and begin to identify uncertaintie...
