Soft Skills: Communication and Teamwork

Data analysis skills are not all technical. To succeed as a data analyst today, strong soft skills are equally as worthy as technical abilities. Communication and teamwork skills allow analysts to effectively share insights, collaborate with colleagues, and drive business decisions.

Communication

Data analysts need to explain complex analysis and insights in a clear, compelling way. They must be able to do this to audiences with varying levels of technical expertise. Strong written and verbal communication skills are key for preparing reports, presentations, and suggestions. These reports must resonate with both executives and frontline employees. The ability to listen well and have constructive discussions about various views or approaches is also a key.
