Steps Involved in Data Analytics
Next step to understanding what data analytics is to learn how data is analyzed in organizations. There are a few steps that are involved in the data analytics lifecycle. Let’s have a look at it with the help of an analogy.
Imagine you are running an e-commerce business and your company has nearly a million in customer base. Your aim is to figure out certain problems related to your business, and subsequently come up with data-driven solutions to grow your business.
Below are the steps that you can take to solve your problems.
1. Understand the problem:
Understanding the business problems, defining the organizational goals, and planning a lucrative solution is the first step in the analytics process. E-commerce companies often encounter issues such as predicting the return of items, giving relevant product recommendations, cancellation of orders, identifying frauds, optimizing vehicle routing, etc.
2. Data Collection:
Next, you need to collect transactional business data and customer-related information from the past few years to address the problems your business is facing. The data can have information about the total units that were sold for a product, the sales, and profit that were made, and also when was the order placed. Past data plays a crucial role in shaping the future of a business.
3. Data Cleaning:
Now, all the data you collect will often be disorderly, messy, and contain unwanted missing values. Such data is not suitable or relevant for performing data analysis. Hence, you need to clean the data to remove unwanted, redundant, and missing values to make it ready for analysis.
4. Data Exploration and Analysis:
After you gather the right data, the next vital step is to execute exploratory data analysis. You can use data visualization and business intelligence tools, data mining techniques, and predictive modeling to analyze, visualize, and predict future outcomes from this data. Applying these methods can tell you the impact and relationship of a certain feature as compared to other variables.
Below are the results you can get from the analysis:
You can identify when a customer purchases the next product.
You can understand how long it took to deliver the product.
You get a better insight into the kind of items a customer looks for, product returns, etc.
You will be able to predict the sales and profit for the next quarter.
You can minimize order cancellation by dispatching only relevant products.
You’ll be able to figure out the shortest route to deliver the product, etc.
5. Interpret the results: The final step is to interpret the results and validate if the outcomes meet your expectations. You can find out hidden patterns and future trends. This will help you gain insights that will support you with appropriate data-driven decision making.
