Hiring a Freelance Data Analyst

Why and when you need a Data Analyst?

Who is able to identify the business needs and recognize how data science can address them? The Data Analyst or business analyst is a type of consultant whose goal is to improve the results of the company by using data, that is, create a data driven organization.

A data analyst consultant defines the business needs, works together with the business and with data scientists to assess, analyze and define application strategies to achieve an impact, across any area of the organization but usually with a focus on commercial activities to drive revenue, operations to bring costs down and improve service and on quality and innovation.

What is not defined cannot be measured. What is not measured can not be improved. What is not improved, is always degraded. - William Thomson Kelvin
