I believe that the 70/30 for success is completely justified. If anything, 70% interpersonal skills is too low. The most important thing in life is the relationships you foster. Your relationships define your network and the opportunities that are opened to you. A persons social growth translates directly over to their professional growth. If you can carry yourself with a high-level charisma and convey your thoughts effectively, people will listen to you. However, one cannot successful communicate their thoughts without a strong technical background. This technical background is still massively outweighed by a successful person’s interpersonal ability. Top level positions in an organization requires a wide social scope from understand the interactions of their organization and staying away of external factors that influences corporate interest. Having these abilities are driven by a person’s interpersonal capabilities. It is important to acknowledge how our education system focuses primarily on developing technical skills. These technical skills are applied to enhances the ability to communicate details to people. Many students excel academically through their technical abilities, but are fearful of social settings. While this person certainly has plenty of knowledge that can contribute enormously to a project, that knowledge isn’t particularly useful if the person cannot work effectively in applying that knowledge and working with the other team members in a project.
