An often-cited estimate is that around 90% of workplace success depends on understanding other people and using strong interpersonal (people) skills , with the remaining 10% attributed to technical skills and knowledge.

Where the “percent” comes from

  • A widely used business text notes that “up to 90 percent of our workplace success depends on an understanding of other people,” emphasizing interpersonal skills as the dominant factor in career progress.
  • Other sources referencing research with executives and leaders often quote similar figures, such as 75–85% of job success coming from people skills and only 15–25% from technical skills.

So, while the exact percentage is an estimate rather than a precise universal law, many business and leadership educators repeat numbers in the 75–90% range to stress how critical it is to understand and work well with others.

What “understanding other people” includes

  • Interpersonal skills: listening, empathy, collaboration, conflict management, and reading others’ needs and motivations.
  • Soft skills more broadly: communication, integrity, adaptability, leadership, and teamwork are consistently rated by executives as crucial for long‑term success.

In modern workplaces—especially in knowledge and service roles—these people- focused abilities often determine who gets promoted, trusted with key projects, and seen as a leader.
