Business Intelligence covers collecting, preparing, presenting, analyzing, making available, and ultimately using data. The result is insights and solid decision-making foundations. This makes it possible to take more objective decisions with measurably better outcomes.

BI includes the strategies, methods, and tools used in this process to turn raw data into valuable insights. Used well, it enables you and your team to test, analyze, and learn faster and more reliably. Optimization processes become more effective and competitiveness improves.


The following article provides a comprehensive beginner guide to business intelligence and making data usable. It covers relevance, benefits, and concrete ways to get started.

Key takeaways

  • Self-service BI makes business intelligence accessible and usable without technical prior knowledge.
  • BI leads to faster, lower-risk decisions with sustainably better results.
  • The BI cycle enables continuous, proactive identification of bottlenecks, opportunities, and trends.

What is Business Intelligence?

Business Intelligence is meant to create clarity and decision-making foundations based on data.

It includes all of the strategies, people, software, and processes behind it. Every business function generates data that can be collected and used. How much revenue has accounting captured? How much is the marketing campaign costing? How much time passes between first contact and purchase?

So BI is not just about the dashboards and reports people see at the end. It is about deciding which data helps decision-makers and teams improve over time. That includes clarifying which data already exists in the company and which data should exist, how it should be prioritized, how it should be captured, and which solution should be used to store, manage, and visualize it.

In the end, Business Intelligence is about making relevant data discoverable, available, and usable.

Business Intelligence, reporting, analytics, and data science

These terms are often used interchangeably. In practice, they serve different goals and produce different outputs.

Guiding questionTypical outputEspecially useful for
Business IntelligenceWhere does the business stand right now?KPI dashboards, standardized evaluations, decision supportOngoing steering and transparency
ReportingWhat happened?Recurring reports, monthly or weekly summariesStructured look-backs
Business AnalyticsWhy did it happen and what works?Deep dives, segment comparisons, root-cause analysisOptimization and better action
Data ScienceWhat is likely to happen next?Forecasts, models, scoringComplex patterns and prediction

Business Intelligence forms the foundation in this setup. It creates the structured overview that reporting, analytics, and data science build on. If BI is set up cleanly, it also establishes the basis for more advanced analysis.

Building blocks, types, and typical setups

Especially with modern self-service BI tools, the work around these components can be reduced almost to zero—so anyone can use the benefits of business intelligence without prior knowledge and without many resources. These are the typical business intelligence building blocks:

Data sources: internal systems (e.g., ERP, CRM, shop, accounting, Excel) and external sources (e.g., website analytics, ad platforms, market data).

Data integration and preparation: data gets connected, cleaned, standardized, and transformed. This is often automated via connectors and pipelines (commonly called ETL/ELT).

Central data base: a central place where structured data is stored, e.g. a data warehouse or a data lake. The goal is a shared, consistent foundation of numbers.

Data model and metric logic: raw data is organized so it can be analyzed meaningfully. This includes clear definitions of metrics (e.g., “revenue”, “gross margin”, “active customers”) and the logic behind them—so everyone means the same thing.

Analysis and visualization: dashboards, reports, and ad-hoc analyses make data understandable and filterable. Good visualization helps spot patterns, outliers, and trends quickly.

Delivery and use: information must reach the right people at the right time—e.g., via interactive dashboards, scheduled reports, or alerts on thresholds.

Governance and operations: permissions and roles, documentation, data quality, refresh cycles, and monitoring are crucial for long-term reliability. For European companies, GDPR is a key requirement.

BI questions can also be grouped into four types—depending on which decision they support:

  • Descriptive: What happened? (reporting, monitoring)
  • Diagnostic: Why did it happen? (root cause analysis, segmentation, drill-down)
  • Predictive: What will likely happen? (forecasts, trend analyses)
  • Prescriptive: What should we do? (recommendations, rules, scenarios)

In practice, there are different ways to implement these building blocks. Three typical setups are:

1) In-house / “toolbox setup” (combining separate components)
Here, individual building blocks are assembled separately—for example, a tool for data integration, a central database (data warehouse), and a visualization/reporting tool. This offers a lot of control, but also requires more planning, maintenance, and technical know-how.

  • Pros: very flexible, scalable, full control over data model and storage, good for complex requirements
  • Cons: high initial effort, ongoing operational and maintenance work, responsibilities for data quality, updates, and monitoring must be defined

2) Integrated BI tools / “all-in-one approach” (one solution covers multiple building blocks)
Here, a BI solution takes over many steps in one system: connecting data, preparing, modeling, and making it usable in dashboards/reports. This is often quick to set up and reduces technical effort. Depending on the provider, there can be limitations for very specific data models, integrations, or export/automation requirements.

  • Pros: fast start, fewer technical hurdles, often includes templates and self-service features, quick results
  • Cons: less flexibility for modeling and custom logic depending on setup, potential limits for highly individual requirements, possible tool lock-in

3) Hybrid (combining central data base and BI tool)
Many companies combine both: e.g. a (cloud) data warehouse as the central data base and a BI tool as the frontend for analysis and dashboards. A step-by-step approach is also common: start quickly, later move parts out or add components.

  • Pros: balance between speed and control, often easy to extend
  • Cons: more integration and coordination effort than “everything in one tool”

Which setup is best depends on resources, complexity, data ownership requirements, and the desired speed. The next section shows how BI typically works in practice—independent of the setup.

How does Business Intelligence work in practice?

BI usually—and ideally—runs as a continuous BI cycle. Once established, the process produces valuable insights continuously and improves decision quality over time.

Mapping these steps internally without supporting software takes significant effort. Modern BI solutions can take over many of these steps.

Business intelligence cycle from data collection to decisions
BI cycle: collect data, prepare, analyze, decide
  1. Collecting data

    Internal systems (e.g., databases, ERP, CRM, Excel) and external systems (e.g., website analytics, social media, market research) provide a wide variety of data. Depending on the goals, these sources should be integrated by priority.

  2. Data integration and preparation

    This includes cleaning and transforming data, as well as storing it and making it accessible in a central place. One option is an internal data warehouse as the central database. For many companies, a BI solution (or a connected cloud setup) can handle this instead—without having to run their own infrastructure.

  3. Visualization and analysis

    Analysis software helps explore and filter the required data and time ranges. Patterns and anomalies become visible quickly. This makes it possible to identify trends, optimization potential, or new market opportunities. These insights can directly inform recommendations for action.

  1. Delivery and use of insights

    Interactive dashboards or reports provide, depending on needs, the flexibility or the overview to quickly grasp the most important information. This can be used directly by teams as decision-making foundations and/or for reporting to leaders and decision-makers.

The outcomes of these actions flow back into the BI process as feedback.

In the BI cycle, data is collected, analyzed, and used again and again—so decisions and the business improve continuously.

Who can and should use Business Intelligence?

In the past, static reports were produced periodically and with significant manual effort. Today there are simple, fast, dynamic, and interactive solutions. While some BI applications are complex to set up and use, others enable self-service BI.

Self-service BI means that setting up and using a BI solution does not require prior knowledge or expertise. Easy connections, dashboard/report templates, and intuitive guidance make it possible to start the BI process in just a few clicks.

Business intelligence is no longer reserved for large corporations with many resources. It does not require dedicated BI specialists in the company: departments, management, small businesses, and freelancers can—and should—use BI alike.

Studies on successful BI adoption show:

Fact

Organizations that rate BI as particularly successful do not only provide analytics to executives. They also deliberately involve business users, customers, partners, and suppliers.

What benefits arise from Business Intelligence?

By turning data into concrete value, BI can deliver significant benefits.

  • Faster decisions with higher quality: up-to-date and reliable information is always available, reducing risks while maximizing opportunities.
  • Optimized internal processes: automated reports and dashboards save time and resources across departments. Bottlenecks and inefficiencies become visible and can be addressed proactively.
  • Better customer understanding: analyses of purchase patterns, customer feedback, and contextual KPIs provide strong optimization potential. Customers become more satisfied and relationships more profitable.
  • Competitive advantage through fast response: trends, risks, opportunities, problems, and other market shifts become visible—so strategy can adapt quickly.
Fact

BI often works indirectly: it strengthens learning and innovation, which then improve performance. In this setting, the direct effect of BI on performance is not significant—highlighting the importance of the “BI cycle” and actually using insights.

Of course, the concrete benefits always depend on correct implementation.

Defining clear goals (e.g., reduce costs in process X by Y%, increase customer satisfaction in area Z) and aligning the BI strategy accordingly can help.

The right start with Business Intelligence

Getting started with BI doesn’t have to be a huge project. Often it’s enough to start with one concrete use case and expand it step by step.

A typical BI introduction process looks like this:

  1. Define goals and questions

    Which problems should be solved—or which areas improved? For example: reduce costs in a process, increase revenue in a channel, or improve customer satisfaction.

  2. Identify relevant data sources

    Which systems contain the information to answer these questions? Typical sources include CRM, ERP, shop systems, accounting, support tools, or website analytics.

  3. Choose a suitable BI solution

    Depending on budget and resources, select a business intelligence or self-service BI solution that can connect to the most important systems with minimal effort.

  4. Build the first dashboard or report

    Start with a few central metrics and build an initial dashboard. It shows the most important KPIs at a glance and is used regularly by the relevant people.

  5. Use regularly and evolve

    Feedback from daily use flows back into the BI process. Metrics get refined, additional sources are added, and more dashboards are created as needed.

Frequently asked questions about Business Intelligence

What does Business Intelligence actually do?

Business Intelligence brings data, metrics, and visualization together so companies can understand their current situation and act faster. The focus is not on isolated numbers, but on linking multiple sources into one shared basis for decisions.

When is Business Intelligence worth it?

As soon as decisions regularly depend on distributed data, numbers are being pulled together manually, or teams do not share one common view of the most important metrics. The more operational and frequent the decisions, the greater the leverage.

Do you need a dedicated data team for BI?

Not necessarily. Self-service BI solutions make it possible to get started without specialist roles. What matters more than team size is clarity around goals, data sources, and KPI definitions (see Self-service BI).

Conclusion

Available data is growing and becoming increasingly important. Using it makes companies smarter and more capable of action.

Business intelligence is indispensable today so this data actively contributes to value creation.

Whether small start-up or large industrial enterprise: the right strategy to make data usable provides a decisive advantage and contributes significantly to sustainable success.

Successful companies already rely on BI:

Fact

“High performers” with strong revenue and EBIT growth are three times as likely as others to say that their data & analytics initiatives contributed at least 20% to EBIT over the last three years.
