Part 1: 7.5 points
Assume you want to hire a mechanical engineer for your factory. You have short-listed five applicants out of forty, based on their resume and phone interviews. After conducting interviews in person with all of them, you are still not sure who to hire. You decide to use the analytical decision process (AHP) framework for this decision problem.
The job is an entry level position, thus, motivation and discipline seem to be the most critical competencies. Since the new employee will have to work in a team, it is also quite important for the selected candidate to be comfortable working in a team setting. Having good test scores comes after the personality traits. Experience in the industry is useful, but less critical than the other criteria. It is not clear that age makes any difference.
The following is information about these five applicants based on their resume and interviews:
1. Apply the AHP method to determine a ranking of the candidates.
2. To verify the adequacy of your ranking, calculate a consistency index.
Insert all calculation steps in a table format. Make sure you explain every step of the process in your own words.
