The Difference Between a Business Analyst and a Data Analyst

According to Forbes businesses using data analytics including business analytics are 23 times more likely to top their competitors when it comes to customer acquisition.

Data is knowledge, and knowledge is power - but only if you know how to harness it. The most successful organisations have learned how to do just that, and are consistently using business data to drive important decisions to improve their operational efficiency, boost sales and increase revenue among other things. 

But how do they do it? To interpret and derive competitive advantages from data, organisations must apply a combination of both business and data analytics. I.e. you’ve got to have a Business Analyst and a Data Analyst. 

To those not in the know, the two disciplines can seem interchangeable, as both work with data to make decisions and both share a few common skills.

However, the larger the organisation, the more distinct the duties of the roles become, making the differences between the two professions important to recognise.

In this article, we’ll examine what makes each role unique, as well the shared skills required to become a Business Analyst or a Data Analyst. By the end, you should have a better idea about which career path would be best suited to you.

Business analytics versus data analytics: what’s the difference?

Business analytics and data analytics share a few similarities. They are both concerned with manipulating and extracting insights from data and using the results to inform decision making within the business. However, the ways in which each function goes about that process differ.

Business analytics is about interpreting an organisation’s data to inform decisions that will have far reaching implications for the business as a whole.

Its main focus is to analyse data to provide the various types of information needed to implement change on an organisational level. For example, the steps needed to meet digital transformation goals.

Data analytics involves combing through massive datasets to reveal patterns, trends, risks, opportunities, draw conclusions about hypotheses, and support business decisions with data-driven insights.

Difference between business analytics and data anlytics

After reading the above definitions, on a surface level it’s easy to see why the two are often confused for one another! Let’s take a closer look at the individual responsibilities of a Business Analyst versus a Data Analyst for greater clarity.

What does a Business Analyst do?

As discussed above, a Business Analyst’s role is to analyse business data from various sources to identify problems and formulate strategic solutions. A Business Analyst usually sits and liaises between a technical and a business team.

Let’s consider five typical day-to-day duties to understand the role better. On starting a new project, a Business Analyst will:

1. Talks to the business and technical teams: Identifies any problems or questions that need to be investigated. In communicating with these teams, the Business Analyst will identify the specific digital/technological needs of stakeholders and begin the strategy formulation process.

2. Perform a requirement analysis: Based on that initial communication, the next step for the Business Analyst is to perform a requirement analysis and write up some accompanying requirement documentation. To put this in context, consider the following example.

Let’s say our Business Analyst talks to a large business and finds out that they are keen to move the majority of their business processes to the cloud.

The Business Analyst would carry out research and analysis to identify and understand which cloud facilities and services would benefit the business most in terms of minimising risks and costs among other things.

The Business Analyst would then prepare a requirement document listing these findings and specifications. This document serves as a reference roadmap or blueprint to the relevant teams that would handle the move to the cloud.

3 Prepare design mock-ups: The next step sees the Business Analyst prepare some designs and mock-ups to give stakeholders a better conceptual understanding of how the finished solution will look, feel and function.

Creating a mock-up ensures that both the Business Analyst and relevant stakeholders are on the same page about what is needed.

4 Prepare test case scenarios: Similarly, the Business Analyst will also prepare a few key test case scenarios, so that when the new system is complete, the engineers will know what kind of factors they need to test to assess that the system is doing what it’s supposed to be doing and is fit for purpose.

5. Communicate ideas effectively: A big part of a Business Analyst’s role is communication skills. A Business Analyst is expected to be able interpret data to prepare and confidently deliver business proposals, presentations and be able to communicate effectively with clients.

What does a Data Analyst do?

Similar to a Business Analyst, a Data Analyst usually sits and liaises between two teams - but in this case, the data team and a business team. The critical difference here is that where a Business Analyst would prepare some documentation as to what is required, they are not expected to build the technological solutions.

This is the responsibility of software developers and the testing is performed by test analysts, with the overall project being maintained by the project management team.

However, though a Data Analyst liaises between business and data teams, they are not only expected to understand what is required, it is also expected of them to deliver solutions. This requires a mix of data and technical skills.

On a typical project, a Data Analyst will be expected to:

1. Talk to the business and data teams: Data analysts find out what is required and what kinds of resources and information are available to deliver on those requirements.

To contextualise this idea, let’s say a business requires a new human resources dashboard. The Data Analyst would first contact the HR Manager to understand what they need and want from a dashboard and how it should function.

Next, the Data Analyst will liaise with the data team to find out what sorts of data are available and what sorts of systems are being used that could facilitate the new dashboard.

2. Analyse the data: Based on the two sets of information collected from the data and business teams, the Data Analyst will begin the process of analysing the data to build the requested report/dashboard/other data solution.

It’s at this point where the Data Analyst’s technical skills come into play and they will use tools like PowerBI, SAS, Python or Tableau among others to build a solution, as is the case in the example above, a new HR data dashboard.

3. Test the reports and/or dashboards: Before sharing it with other relevant parties, the Data Analyst must next test the report and/or dashboard to make sure that it is functional and producing the correct output and analyses.

This involves testing various scenarios. For example, what happens if the data changes? What happens if there isn’t enough data to fill all of the listed fields? How is it going to react?

4. Prepare design mock-ups: Like a Business Analyst, a Data Analyst will also prepare design mock-ups to facilitate effective communication. Oftentimes clients or relevant stakeholders don’t really know how a finished report or dashboard should look and only have an idea of what they want it to be able to do.

Creating mock-ups enables the Data Analyst to confirm whether or not they are on the right track before putting in the work to build a final solution.

Essential skills and prerequisites: Business Analyst versus Data Analyst

Now that we have a better idea of how the two roles differ in terms of day-to-day responsibilities, let’s take a look at the kinds of skills you need to become a Business Analyst versus a Data Analyst. We’ll also discuss the shared skills essential to excel in either role.


The skills needed to succeed as a Business Analyst:
