Data assessment and audits
Data assessment and audits enable consultants to identify opportunities for improvement, uncover risks, and recommend optimal strategies for data adoption, modernization, analytics, etc. Assessment and audits are essential to helping companies make smarter decisions based on facts, rather than a gut feeling.

Predictive modeling
Predictive modeling is a process used to anticipate future events by examining patterns in a given dataset. It’s a process that calculates current and past data to make the most accurate forecast possible.

Data management
Data management involves gathering, arranging, safeguarding, and storing an organization’s data to enable analysis to take place. In the face of organizations generating and utilizing data at unprecedented rates, data management solutions have become crucial for interpreting large quantities of data.

Data visualization
Many data analytics consultancy companies offer data visualization services that can help companies identify trends, patterns and anomalies using pie graphs, charts and other visual aids. Doing so is effective; some say our brains are hard-wired to quickly analyze and understand visualizations much quicker than reading text.

Data storytelling
Data storytelling is much like regular storytelling, but with the added benefit of walking the audience through a data “journey” — complemented with graphs and charts. This helps company higher-ups fully understand the findings and empowers them to make decisions quickly and with confidence. 

Customer data platform consulting
A Customer Data Platform (CDP) is software that gathers information from various tools and creates a single, central database with details about every interaction customers have had with you. This database can then be utilized in many different ways to make more personalized marketing campaigns that resonate with customers.

Testing and personalization
Data analytics consultancies offer testing and personalization services that involve conducting experiments to optimize strategies, content, and user experiences. Through A/B testing, multivariate testing, and personalized content deployment, these services aim to enhance customer engagement and satisfaction while maximizing business outcomes.

Data and AI engineering

Integration with AI systems, the development of ELT and ETL pipelines, cloud migration, and engineering support are the typical services that fall into this category.

Monitoring and support
Monitoring is central to preventing AI analytics issues like model drift, ensuring compliance, and maintaining the high performance of data infrastructures. A consultancy firm can set up monitoring solutions, provide ongoing support for both technical solutions, and continually enhance a company’s data analytics capabilities.

4 types of data analysis

The four types of analytics found below form a continuum, with each stage building upon the previous one to extract more value from data. Organizations often use a combination of these analytics types to gain a comprehensive view of their data, and make changes to their customer engagements and internal operations.

Descriptive analytics
Descriptive analytics summarizes historical data, describing what has happened in the past and providing a clear picture of events or patterns. This type of analytics uses techniques like data aggregation, data mining, and visualization to present data in a way that’s understandable and useful. Typical examples include sales reports, summaries of website traffic, or demographic data.

Diagnostic analytics
Diagnostic analytics dives deeper into data patterns to uncover the root causes of specific events. Once descriptive analytics reveals what happened, diagnostic analytics aims to explain why. This type of analysis relies on drill-downs, data segmentation, and correlation analysis to identify relationships and uncover the factors influencing certain outcomes. For instance, it might help a company figure out why sales decreased in a particular region, or why website traffic peaked during a specific period.

Predictive analytics
Predictive analytics focuses on forecasting future outcomes. It uses statistical algorithms, machine learning techniques, and modeling to make predictions about what might happen. Predictive analytics can estimate probabilities and trends, fostering informed decisions about potential future events. Examples include sales forecasting, predicting customer churn, or anticipating equipment failures.

Prescriptive analytics
Prescriptive analytics goes beyond predicting what might happen by pointing to a specific course of action to take. It leverages optimization algorithms, simulation, and machine learning to recommend actions that can maximize desired outcomes or minimize undesired ones. For instance, it might suggest optimal pricing strategies, inventory management plans, or treatment plans in healthcare.

Data analytics use cases by industry

Data analytics consulting is revolutionizing industries across the board, from healthcare to retail and financial services. Let’s take a closer look at how data analytics is being utilized in these sectors.

What to look for when hiring a data analytics consultancy

There are plenty of companies out there offering analytics and big data consulting. Inevitably, some of them will be better than others. This is why it’s important to do your homework before selecting a data analytics company. Here are a few things to consider.

Look into their past projects
Selecting a data consultancy requires an in-depth review of the consultancy’s track record. Thoroughly evaluate their historical projects, case studies, and client feedback.

Find out if they have an ethics policy
Working with data consultants often involves dealing with sensitive and confidential data, which means the consultancy must not divulge anything they see in the data. This might sound like a no-brainer, but some data analytics consultants are more scrupulous than others.

Look at their range of services offered
A comprehensive suite of services suggests a well-rounded understanding of data management, data analytics, and business intelligence. It also shows the company has a holistic view of big data consulting, and can likely handle any aspect of your data objectives.

Figure out how they are at communication
As with any leadership or consultancy position, communication is critical. Even if you have the right ideas and solutions, it will not be as effective if you cannot communicate them correctly to the team efficiently and timely.

Ask if they have experience in your industry
Another good idea is to find out if the data consultant has performed data analytics in your industry. Data analysis is not a one-size-fits-all field, so finding someone who understands the unique challenges and nuances of your industry is crucial.


Data is abundant in every modern business and highly valuable, so much so that it’s been called “the new oil.” And just like oil, data’s value is only revealed when it is refined.
This value of data analytics is reflected in how fast the market is growing. The size of the data analytics market worldwide is estimated to be around $112.8 billion USD in 2023. It is projected to balloon to around $303 billion USD by 2030.
If your business has been considering a big data consultancy but hasn’t yet pulled the trigger, then 2024 may be the right time. You must assume that your competitors are leveraging the power of data analytics, and to delay any longer, your company risks falling behind.
