External Factor Evaluation (EFE) matrix method is a strategic-management tool often used for assessment of current business conditions. The EFE matrix is a good tool to visualize and prioritize the opportunities and threats that a business is facing. The EFE matrix is very similar to the IFE matrix. The major difference between the EFE matrix and the IFE matrix is the type of factors that are included in the model. While the IFE matrix deals with internal factors, the EFE matrix is concerned solely with external factors. External factors assessed in the EFE matrix are the ones that are subjected to the will of social, economic, political, legal, and other external forces. EFE MATRIX:

List factors: The first step is to gather a list of external factors. Divide factors into two groups: opportunities and threats. Assign weights: Assign a weight to each factor. The value of each weight should be between 0 and 1 (or alternatively between 10 and 100 if you use the 10 to 100 scale). Zero means the factor is not important. One or hundred means that the factor is the most influential and critical one.  The total value of all weights together should equal 1 or 100. Rate factors: Assign a rating to each factor. Rating should be between 1 and 4. Rating indicates how effective the firm’s current strategies respond to the factor. 1 = the response is poor. 2 = the response is below average. 3 = above average. 4 = superior. Weights are industry-specific. Ratings are company-specific. Multiply weights by ratings: Multiply each factor weight with its rating. This will calculate the weighted scorefor each factor. Total all weighted scores: Add all weighted scores for each factor. This will calculate the total weighted score for the company.
