Case Study: Static Analysis Leads to 30% Fewer Defects


Increasing Productivity and Quality in Mission-Critical Software

ScreenShot695Thales Italia boasts a solid portfolio of products and technologies destined for both civil and military markets. They offer technological solutions that address the security and transportation industries (with expertise in railway signaling and protection/surveillance of critical infrastructures); in the defense division (with expertise in military communications and war electronics); and in the air traffic management field (with expertise in landing, navigation, and surveillance systems).

Thales decided to apply static analysis via Parasoft’s Development Testing Platform to its Integrated Tramway Management Solutions project— then later deployed it across the entire Automatic Vehicle Location System division. The result: Thales reduced its rate of defective components by 30% and significantly increased application performance.

Thales was looking for a solution that would simplify configuring, deploying, and managing a standardized rule set across a team or department. Specific requirements included: 

  • All-in-one development testing capabilities
  • Ability to extend configure their unique coding standards
  • Ease of project setup 
  • Seamless integration into their development/testing environments
  • Detection of runtime defects


Parasoft's Development Testing Platform enabled Thales to efficiently and consistently apply a broad set of complementary defect prevention practices, which greatly improves productivity by helping developers eliminate problems when they are easiest and fastest to fix (and before they lead to additional defects). The architect can easily take the rules and settings designed for one code base and apply them to another code base— with any necessary adjustments and modifications for the new context. This is especially important when the developers work in diverse environments that use different technologies.

Being able to adjust a rule in a matter of seconds then immediately deploy it across all of the developers’ desktop installations allowed them to achieve a huge increase in productivity. Thales also achieved productivity gains by having detailed results reported directly in the developers’ work environment.  The ability to click on a reported violation and learn how and why to fix the flagged code helped the team start writing lower-risk code as a matter of habit.

Static Analysis Results: 30% Fewer Defects

“One of the greatest advantages of Parasoft's static analysis is that it taught our engineers how to become better developers” remarks Alessandro Orsi, the AVLS Systems Product Manager. “We are finding fewer and fewer defects in the code base because developers are learning how to write better Java code. As the developers grow comfortable with the existing rule set, the architects incrementally extend it to include more rules. As expected, this results in better code. It’s a cyclic process.”

“When we compare defect rates in the component before and after adopting Parasoft’s static
analysis, we find that we are now achieving 30% fewer defects,” Orsi continues. “If other suppliers would provide the type of support that we’ve had from Parasoft, the world would be perfect. The support we have received from Parasoft has been truly remarkable”.
