What are the different roles and responsibilities of a data scientist?
Understanding the business problem : Before a data scientist could perform any operation, the first and foremost responsibility is to clearly understand the business problem. Understanding the problem also includes determining the objectives.
Probing : Asking several questions to avoid confusion and get the right information is also one of the major job roles of a data scientist.
Data collection : Once the problem is understood, a data scientist gathers data from multiple channels such as web servers, databases, etc. Retrieving the right data isn't an easy task as it demands a lot of effort and time.
Data Preparation : This process is divided into two categories. Namely, data cleaning and data transformation, The process of data cleaning consumes a lot of time as a data scientist encounters multiple complex scenarios to deal with. Working on inconsistent databases, duplicate data, misspelled attributes, etc are examples of the complex issues. Data transformation is the process of modifying the cleaned data considering the determined mapping route. Transforming the data that is understandable by the people involved in the project is a challenging task which any data scientist would encounter on a daily routine.
Data Analysis : Data analysis is the process of understanding what to be done with the derived data by applying various tools of data science. This process involves defining and refining the data. Data analysis is the most important phase of data science as it involves discovering the right way to execute the process using the given data.
Data Modeling : Data modeling is applying various approaches and systems to get the best model that fits the requirements to solve the existing business problems. Training the data models and testing them are two continuous processes involved in this specific phase of data science
Data Visualization and Communication : Creating effective reports is an important job role of a data scientist. Communicating with the clients and other people involved in the data science project to describe the derived solution by using various data visualization tools.
Data Deployment : Before deploying the project, data scientists will have to test them in a preproduction environment. Once it is successful, the data scientists would deploy it to the clients.
Data Maintenance :Once the project is delivered maintaining the analytics of the performance of the project would be the last duty involved in a data science project.
