After years of experimentation, a key question comes to the fore in 2026:
Where does AI generate the greatest business value—measurable, scalable, and sustainable?
Companies have understood that AI is not relevant because of the technology itself, but because of its contribution to efficiency, planning reliability, risk reduction, and increased sales.
The focus is shifting from "What can AI do?" to "What concrete benefits does AI offer?"
According to PwC, over 70% of executives now evaluate AI primarily based on its financial impact, rather than its innovation potential.* The decisive factor is therefore not whether AI is used, but where.
The four areas where AI is proven to deliver the greatest ROI in 2026
Efficiency gains in operations
This is where most of the "quick" effects occur.
AI reduces manual steps, automates routine decisions, and speeds up processes—especially in areas such as:
-
Reporting & Analysis
-
document processing
-
Classification & Summary
-
Service & Support
-
process automation
ROI effect: less time required, fewer errors, lower process costs.
Gartner rates this area as the "safest, most broadly scalable" ROI lever of all AI use cases.*
Planning & Forecasting: More Precise Decisions
In 2026, the quality of forecasts will become a key success factor.
AI improves:
-
sales forecasts
-
budget compliance
-
capacity planning
-
Project and cost progress
-
demand forecasts
McKinsey shows that companies using AI-supported planning achieve forecasts that are 40–60% more accurate.*
ROI effect: stable margins, fewer surprises, better control.
Risk minimization through early pattern recognition
AI detects risks before humans perceive them:
-
project delays
-
quality issues
-
supply chain risks
-
Churn probabilities
-
budget deviations
Companies react earlier, reduce costs, and stabilize their processes.
ROI effect: fewer unplanned costs, fewer operational disruptions, improved resilience.
Increased sales through data-driven go-to-market optimization
AI improved:
-
lead scoring
-
pricing strategies
-
Cross-selling and upselling potential
-
customer segmentation
-
sales forecasts
According to Deloitte, companies report up to a 10–20% increase in sales when AI is used productively in sales.*
ROI effect: higher sales without increasing costs.
Why many AI initiatives fail to deliver ROI and why 2026 will be different
The bottleneck is rarely the technology.
It is:
-
poor data quality
-
lack of integration
-
unclear goal definitions
-
lack of scaling
In 2026, successful companies will rely on three principles:
-
Business goals first —not technology.
-
Data quality as a foundation – no AI model can solve data problems.
-
Production instead of PoC loops – value is created during ongoing operations.
Conclusion
The question "Is AI worth it?" has been answered: Yes. Specifically, where it has a business impact.
Efficiency, planning, risk, and revenue: These are the levers that will be decisive in 2026.
Companies that consistently align their AI strategy with these four areas achieve the highest return on investment.
