The question is about deciding which outsourcing firm to choose based on a weighted rating system. The rating system takes into account four criteria: Flexibility, Trustworthiness, Price, and Delivery. Each criterion is assigned a weight based on its importance. The higher the weight, the more important the criterion. Each outsourcing firm is then rated on each of these criteria. The rating for each criterion is multiplied by its weight to get a weighted score. The weighted scores of all criteria are then added up to get a total score for each firm. In this case, Manila Call Center has the highest total score, making it the best-rated firm. This is because it has high ratings in the criteria that are considered most important (those with higher weights), such as Trustworthiness, Price, and Delivery. This method of decision making is known as a weighted scoring model, which is a valuable tool in decision making as it allows for subjective qualities to be somewhat objectively quantified
