1Economic Impact Study Results

A new Forrester Total Economic Impact study commissioned by JetBrains reveals that IntelliJ IDEA delivers a 155% return on investment. The analysis, based on a composite organization with 2,000 developers, shows $30.3 million in total benefits against $11.9 million in costs, resulting in a net present value of $18.4 million over three years.

2Rapid Investment Payback Period

The study highlights a swift financial recovery for organizations adopting the platform. The composite organization achieved full payback on its initial investment within just nine months. This rapid return underscores the efficiency gains developers experience when utilizing the IDE's built-in intelligence for complex software development tasks and large-scale enterprise project management.

3Primary Focus on Code Quality

Improved code quality emerged as the most significant benefit identified by all nine interviewed engineering leaders. This encompasses critical development activities such as code review, testing, remediation, debugging, and refactoring. These processes currently account for approximately 30% of a developer's time, with the IDE providing essential support through twenty years of accumulated intelligence.

4Accelerated Pull Request Cycles

The integration of automated inspections and real-time analysis leads to faster pull request cycle times. Forrester models a 15% reduction in cycle time during the first year, increasing to 20% by the third year. This efficiency improvement represents a risk-adjusted present value of $16.3 million, accounting for over half of the total benefits.

5Open Approach to Artificial Intelligence

The study emphasizes the platform's open approach to AI, allowing developers to switch between different models as their specific needs evolve. This flexibility is crucial as teams increasingly adopt AI-assisted development, ensuring that generated code is validated against rigorous quality standards while maintaining the ability to integrate emerging tools into existing workflows.

6Managing Complex Enterprise Codebases

Large, distributed codebases benefit significantly from the IDE's ability to understand dependencies across enterprise architecture. CTOs noted that this capability helps catch potential issues before they reach production environments. A telecommunications director reported a 10% reduction in error rates, highlighting the tool's effectiveness in maintaining stability within highly complex software systems.

7Productivity Gains and Friction Reduction

IntelliJ IDEA improves overall developer productivity by up to 20% through faster throughput and reduced context switching. By consolidating various tools into a single environment, developers experience less friction during their daily tasks. This efficiency allows teams to complete refactoring work significantly faster, such as finishing in five hours instead of eight.

8Scaling Efficiency with AI Agents

As AI agents take on more code generation tasks, the importance of robust IDE support continues to grow. The features that currently assist human developers in writing code are equally applicable to managing agent-generated outputs. This synergy ensures that productivity gains remain sustainable even as the nature of software development shifts toward automation.

9Methodology of the Composite Model

Forrester built the composite organization model by interviewing nine senior engineering and technology leaders from companies with 400 to 4,000 IntelliJ IDEA seats. This representative global financial services company serves as the baseline for all calculations, ensuring the findings reflect real-world enterprise challenges and the practical benefits of using professional-grade development tools.

10Strategic Value of IDE Intelligence

The study confirms that the value of an IDE extends beyond simple text editing. By providing deep insights into code structure and project dependencies, the platform acts as a force multiplier for engineering teams. This intelligence is particularly valuable in environments where maintaining high standards across thousands of developers is a constant challenge.

11Future Outlook for Development Teams

As organizations continue to scale their engineering efforts, the reliance on sophisticated development environments will likely intensify. The projected growth in productivity benefits suggests that tools offering integrated testing and refactoring will remain central to enterprise strategy. Companies that prioritize these investments are better positioned to manage the complexities of modern software delivery.

12Conclusion on Long-term ROI

The 155% ROI demonstrates that investing in high-quality development tools is a sound financial decision for large enterprises. By reducing time spent on manual remediation and improving overall code quality, organizations can achieve significant cost savings. These results highlight the critical role of developer experience in driving broader business success and efficiency.
