Do you work in a team? If so, you know how important it is to write, debug, and compile code within a single environment. Decision-makers need numbers and perfect reasoning before they make up their mind to invest in an IDE that will be shared by all the team members.

If you are planning to present your manager with ideas on how the right choice of an IDE can increase the productivity of the whole team, a new Forrester Consulting Total Economic Impact™ Study commissioned by JetBrains can help.

It explains why IntelliJ IDEA is an investment that pays off, providing the Return On Investment (ROI), percentage increase in developer productivity and code quality, and many other characteristics that can help managers who want to adopt a single environment for their development teams.

We’ve summarized the study below. You can find more detailed information on our website, including the downloadable full study with more statistics and an in-depth analysis of the potential financial impact.


Forrester Consulting interviewed four customers using IntelliJ IDEA. They shared their vision of the development process from different angles, including technical and business perspectives.

Before they made the decision to use IntelliJ IDEA, key investment drivers for the companies were ease of use and support for effective features that work smoothly and bug-free.

Benefits of using IntelliJ IDEA

After the companies started using IntelliJ IDEA, they saw both quantitative and qualitative benefits, which helped reduce costs.

Measurable benefits included:

  • Higher developer productivity Through better focus, live analysis, and real-time recommendations, developers completed their work 20% faster and with less disruption. They became more confident in writing code with consistent style, fewer bugs and exceptions, better referencing of the existing code base, and more.
  • Improved code quality With IntelliJ IDEA’s reliable auto-completion, code review tools, and a built-in debugger, it became easier for QA specialists to perform tests and for developers to review their code.
  • Increased productivity in code maintenance Since the code quality increased, there were fewer bugs that risked slipping through QA. With the fewer bugs came a reduced need to maintain the code and fix issues when they occurred.
  • Faster and more efficient onboarding It became easier to onboard new employees as the product offered a comprehensive user interface, shared configuration files, and style guides and templates that developers could rely on during their first weeks.

In addition to these quantitative cost-efficiency benefits, there were several qualitative perks. Developers could:

  • Feel more confident in the code they created.
  • Share and understand their teammates’ code faster because of its increased consistency.
  • Rely on peer reviews that are focused on big-picture items rather than trivial errors and issues.


The study results are quite promising! Here is what a company can expect three years after adopting IntelliJ IDEA:

  • 628% Return on Investment
  • 144 hours saved per user
  • $2,027 net annual benefit per user

We hope the results of this study can be helpful for the organizations where you work. Feel free to ask any questions and share your thoughts in the comments.

Happy developing!
