Core competencies are the company’s capabilities that distinguish a firm from its competitors. They help define the strategic advantages of the business and build the foundation of the company’s competitiveness. Furthermore, core competencies guide the brand reputation alongside enabling business growth and developing its marketing strategy. Failing to define and nurture the business’ core competencies will lose the battle against your competition. Therefore, you should start outsourcing with side competencies first. After the side competencies are covered well, you can gradually continue with outsourcing core competencies.
