Everything is “data-driven” these days. Data-driven marketing, data-driven management, data-driven business decisions — information is truly power for organizations. 

And to harness the full potential of data, businesses need to understand what’s called the data lifecycle — the stages that data passes through.

The data lifecycle is comprised of eight stages. We’ll explain each one, who is involved, and provide concrete examples through the lens of a sample project involving customer sentiment analysis. 

In this sample project, Company X wants to analyze customer sentiment from social media to improve its customer service approach.

What is the Data Lifecycle?

The data lifecycle encompasses a series of eight stages through which data passes — from its creation to its end use in decision-making. Each stage involves specific processes and stakeholders that ensure data is properly managed, analyzed, and utilized.

Understanding the data lifecycle helps organizations optimize their data-handling practices. This leads to better data quality, improved security, and smarter business decisions. By effectively navigating these eight stages, organizations can transform raw data into information they can really use to drive innovation.

6. Data Analysis

Data analysis, the sixth stage in the data lifecycle, is where real value is discovered by using analytical tools and techniques to identify patterns, trends, and correlations in data. The key components involved are:

  • Descriptive analytics: Summarizes past data to help organizations understand what has happened.
  • Diagnostic analytics: Examines data to determine why certain events or issues occurred.
  • Predictive analytics: Uses historical data and machine learning (ML) to forecast trends and future outcomes.
  • Prescriptive analytics: Guides future actions by predicting optimal steps to reach a specific goal.

This stage makes it possible to extract meaningful insights from data so businesses can make more informed decisions.

Who is involved in Data Analysis?

Perhaps obviously, the main role involved in data analytics is a data analyst, who oversees some of this work. For more advanced tasks around predictive and prescriptive analytics, a data scientist is usually involved. Business stakeholders will also be included in data analysis processes so they’re able to ask questions and provide information about company goals. Other roles typically involved in data analysis include:

  • Data analysts: Take on most data analysis tasks. For more complex tasks involving machine learning, they would rely on a data scientist.
  • Data scientists: Facilitate better decision-making by ensuring data is secure, accurate, and accessible, and doing advanced data work like predictive and prescriptive analytics.
