How to determine if software is reliable?

What is the failure probability of your software system for the next month and what is the damage? What is the capacity for defect correction you should anticipate? How much longer do you need to keep on testing?

Refis measures the reliability of your software system and helps to reach quality goals. Refis is one of the founders of the TOPAAS-model for software reliability and together with the Eindhoven University of Technology it developed the SRE-tool for Reliability Growth Models  (RGM).

Refis measures software reliability and provides project and test management capacity to meet reliability criteria!

Refis improves the quality of information systems, development and test processes.

In today’s society the reliability of information systems is getting more and more important. Information system failures have increasing impact and lead to more damage than ever. It is therefore essential that risks are thoroughly evaluated before a new system or release is deployed. We can no longer afford to take those kind of decisions based on gut feeling only.

Our goals is to provide that necessary knowlegde about reliability and failure probability. Therefore we aim at research, development, consultancy and training in Reliability Engineering For Information Systems.



In collaboration with universities, customers and colleagues, Refis is extending the feasibility of reliability concepts, improving existing tools and expanding knowledge and experience.


Together with customers Refis develops and implements metrics, which provide insight information in performance and efficiency of software development processes and products.


Refis consultants are reliable partners in development, quality assurance and control. Operating as consultant, project manager or test manager, their skills and experience contribute to an actual improvement of information process and business.


Refis training in testing, quality assurance and control and reliability engineering excel in feasibility and down to earth content.
