Key Responsibilities – The Day-to-Day of a BI Analyst

[bdjakaria76]

Data Scientist: Data Scientists typically work with more complex, often unstructured data, employing advanced statistical modeling, machine learning algorithms, and predictive analytics to uncover deeper insights and build data products. While a BI Analyst might use predictive models, their toolkit is often more focused on descriptive and diagnostic analytics.

vs. Data Engineer: Data Engineers are focused on the infrastructure and architecture of data. They build and maintain the systems that collect, store, and process data, ensuring data is available and accessible for analysts and scientists. BI Analysts are consumers of the data pipelines built by Data Engineers.
The specific tasks of a BI Analyst can vary based on the whatsapp number list organization's size, industry, and data maturity. However, a common thread of responsibilities runs through most BI Analyst roles:

Understanding Business Requirements:

Collaborating with business stakeholders (e.g., management, sales, marketing, operations) to understand their challenges, goals, and information needs.
Translating vague business questions into specific, answerable analytical queries.
Defining key performance indicators (KPIs) and metrics relevant to business objectives.
Data Collection and Preparation:

Identifying and accessing relevant data sources (databases, data warehouses, APIs, flat files, etc.).
Performing data extraction, transformation, and loading (ETL) processes, though often this is supported by Data Engineers.
Cleaning and validating data to ensure accuracy, completeness, and consistency. This can involve handling missing values, outliers, and inconsistencies.
Integrating data from multiple sources to create a unified view.
