The most useful starting point is not a fashionable model or platform: it is a specific decision that could improve, the data that can inform it, and an operating team able to act on the result.
Use cases range from personalizing offers and forecasting demand to identifying suspicious transactions and preventing equipment failures. Their value depends on whether the analysis reaches the right person in time and changes a measurable business outcome.
What can businesses use data science for?
Common business applications fall into four groups: growing revenue and improving customer experience, running operations more efficiently, managing financial and other risks, and creating data-enabled products or services. The same analysis can have different consequences in different businesses, so use cases should be judged by the decision they support rather than by the technique alone.
| Business goal | Example use cases | Decision or action informed |
|---|---|---|
| Grow revenue and improve customer experience | Customer segmentation, personalized marketing, pricing and promotions, recommendations, churn prevention, product development | Which customers to contact, what offer or price to present, what to recommend, or what product feature to improve |
| Improve operations and supply chains | Demand forecasting, inventory planning, predictive maintenance, quality inspection, bottleneck analysis, warehouse and route optimization | What to stock or schedule, where to inspect or maintain, and how to adjust production or shipping |
| Manage risk and financial decisions | Fraud and anomaly detection, credit assessment, cash forecasting, payables analysis, workforce retention and performance management | Which activity merits investigation, how to assess a risk, or where finance and HR teams should focus |
| Create data-enabled offerings | Data or analytics services, data-related products, and improvements to products or production using data | Whether a data capability can provide customer value as a new offering or improve an existing one |
How can analytics grow revenue and improve customer experience?
Segment customers and personalize marketing
Businesses can combine customer behavior, demographics, geography and transaction history to identify groups with different needs or purchasing patterns. A marketing team can then tailor communications and offers rather than sending the same message to everyone.
#1 Best Overall
IBM Think’s article, published November 6, 2025, describes European fuel retailer MOL using loyalty transactions to create product-purchase microsegments across its 2,400 service stations. IBM reports that personalized communications produced returns three times higher than general communications and customer-satisfaction levels 20% higher than competitors. IBM does not date the underlying case in that article; these are reported case results, not forecasts for another company.
Set prices, promotions and retention actions
Dynamic pricing can use demand, competitor prices and customer preferences to inform price changes. Analytics can also help businesses decide which promotions to run, where cross-selling or upselling may fit, and which customers may be at risk of leaving. McKinsey identifies these as customer-facing use cases, but the cited material does not establish a universal pricing formula. Businesses still need to apply their own commercial rules and customer context.
Recommend products and improve them
Viewing behavior can inform recommendations on entertainment services. IBM describes Netflix using viewing habits in this way. Product teams can also analyze diagnostics, telematics and customer or product data to spot possible improvements; IBM describes Honda using vehicle and driver data in engineering. These examples illustrate applications, rather than independently validating the full business effect of either company’s approach.
How can analytics improve business operations?
Forecast demand and connect the forecast to inventory
Demand forecasting estimates incoming orders or future demand so a business can coordinate inventory and supply decisions. Gartner describes forecasting incoming product orders alongside optimization, allowing organizations to respond proactively to changing supply-chain demand, including when historical records are incomplete or dirty. A forecast is useful only if it arrives early enough to inform a purchasing, production or allocation decision.
Schedule maintenance before equipment fails
Predictive maintenance uses equipment-condition and operating data to estimate failure risk. A maintenance team can use that estimate to schedule inspection or service before a breakdown, rather than relying only on a fixed timetable or waiting for failure.
OECD reports estimates attributed to Dilda et al. (2017): predictive maintenance typically reduces machine downtime by 30%–50% and increases machine life by 20%–40%. These are reported general estimates, not guaranteed results for a particular company; assets, data and implementation affect outcomes.
Find defects and production bottlenecks earlier
Predictive analysis and computer vision can help identify quality problems or inefficiencies earlier in production. IBM Think’s 2025 article reports that Frito-Lay used computer vision to assess potatoes and saved over USD 300,000. The article does not state when that implementation took place, and the reported result should not be treated as a general savings estimate.
Optimize warehouse and shipping work
Inventory, shipping and route data can help locate logistics bottlenecks. IBM reports that truck-parts distributor FleetPride used data mining and predictive analytics in warehouse and shipping operations, doubling productivity and reducing shipping costs. IBM does not provide a percentage reduction for shipping costs in the cited account.

Flag suspicious transactions for investigation
Fraud and anomaly detection looks for patterns in transaction activity that may warrant review or intervention. The practical purpose is to prioritize attention and help a team respond—not to treat every flagged transaction as confirmed fraud. IBM and McKinsey both identify fraud detection as a business application of analytics.
Broaden credit assessment carefully
Credit assessment can combine traditional repayment records with other information, such as income, rent, utility payments or account-transaction histories. IBM describes these data sources as a way to assess creditworthiness. Wider data coverage does not remove the need to consider data quality, fairness, privacy and applicable law. The cited material does not provide jurisdiction-specific legal advice.
Support finance and workforce decisions
Analytics can inform cash forecasts, payables performance and demand forecasting in finance, as well as performance management and retention in HR. In an example involving a global agrochemical company, McKinsey reports these as priorities for the respective functions. They are reported priorities, not a universal ranking of what every finance or HR team should tackle first.
Can data analytics create new products or services?
Some businesses use data to improve existing products or internal processes; others use it to create data-related products or offer data and analytics as a service. McKinsey distinguishes these new business models from customer-focused top-line use cases and internal process improvements. OECD similarly discusses selling or licensing data, creating data-related products, and applying data to improve products and production.
Rank #4
A data asset is not automatically a business offering. A company needs to consider whether it has the rights to use or license the data, whether the data is fit for the proposed purpose, and whether customers receive meaningful value. The cited sources do not support treating raw data as automatically monetizable.
What do big data analytics and data science mean in practice?
“Big data” is not a synonym for every analytics project. IBM describes its relevant characteristics in terms of volume, velocity, variety, veracity and value; which characteristics matter depends on the use case. A business may have a worthwhile analytics opportunity without every one of those dimensions being prominent.
It also helps to distinguish what analysis does from what a business does with it:
- Descriptive reporting summarizes what has happened or what is happening.
- Predictive analysis estimates what may happen, such as future demand or equipment failure risk.
- Prescriptive analysis or optimization helps compare possible actions, such as inventory or supply decisions.
A score or forecast is not itself a decision or an action. Gartner’s examples pair forecasting or simulation with defined actions or optimization, and its stated role for data and analytics is to equip businesses, employees and leaders to make better decisions and improve decision outcomes.

How should a business choose its first use case?
Compare candidate projects by the decision they could improve and the conditions needed to put the result to work. McKinsey frames prioritization around strategic questions, expected impact and barriers such as poor data, dependencies and privacy.
- Name the decision. Specify who will decide what, and what action could change if the analysis is useful.
- Check strategic relevance and likely impact. Link the decision to a business priority and identify a concrete outcome to measure.
- Assess the data. Check availability, quality, freshness and integration effort. A model cannot compensate for information that is missing, stale or difficult to connect.
- Set the timing requirement. Establish how quickly the result must arrive to affect the relevant decision, such as a maintenance schedule or supply response.
- Consider error costs and barriers. Weigh the consequences of false alarms or missed events, along with privacy, legal, governance and dependency constraints.
- Confirm an operating owner. Identify the team that can take the recommended action and the process in which the result will appear.
- Define measurement before implementation. Set a baseline and an outcome measure appropriate to the use case so the business can assess whether the work changed the decision or result.
How should a business measure results?
Choose measures that match the decision rather than reporting model activity as business value. For example, a company can examine forecast usefulness alongside inventory decisions, maintenance analysis alongside downtime, or targeted communications alongside their returns and customer response. These measures are evaluation choices, not performance guarantees.
Published figures differ in source and scope. OECD cites Müller, Fay and vom Brocke (2018) for an association between adoption of big-data-related assets and an average 3%–7% improvement in firm productivity. That association does not prove an analytics project caused the improvement. The predictive-maintenance estimates attributed to Dilda et al. (2017) are a different type of evidence, while the MOL, Frito-Lay and FleetPride figures are company results reported by IBM Think in its 2025 article. Do not add these figures together or assume they use comparable methods.
What does it take to put an analytics use case into operation?
Implementation is more than selecting a model or platform. Data quality, freshness, integration, governance, privacy, skills and adoption all affect whether an insight can be used. Before deployment, a business should clarify who owns the data, who reviews the output, what action follows, and how exceptions or errors are handled. These needs vary by use case; the evidence does not establish one best vendor, platform, model or cloud architecture for every organization.
The central test is operational: can the analysis reach someone who has authority and time to act, within the decision window, through a process that can be measured? If not, the business may have a technically interesting analysis but not an implemented use case.
