Customer Success Story

NSP’s Virtual Target Solution (VTS) team team, decided to begin searching for NEC Telecom Software is made up of 15 people, and enforcing an alternative solution to manual code internal quality initiatives was challenging. reviews and unit testing. Philippines (NSP), a subsidiary Most of the developers were young of NEC Corporation of Japan, is located engineers just learning NSP’s ever- NSP has a high commitment to quality in Manila. NSP develops technologies for important internal quality initiatives, such as and Joel was determined to stay true code review, scope, and range of testing. to that commitment. He had previously broadband and mobile communications, had positive experiences working with as well as IT and network solutions that Until recently, only the two senior level Parasoft Jtest, a solution for Java, so meet the highest level of customer satis- engineers performed reviews of all of the he turned to Parasoft C/C++test, an source code for any given project assigned automated unit testing and coding faction with their high-quality output. to the team. This source code is typically standard analysis solution for C and C++. between 10,000 to 12,000 lines of code. To assist in detecting coding violations, When the VTS team found themselves the VTS team used Parasoft C/C++test working on a project with an extremely tight RuleWizard. Cherry Ann Alib, a software THE CHALLENGE schedule, it was impossible for the senior design engineer, stated, “It’s very useful developers to code review everything. As because we can customize our rules NSP’s Virtual Target Solution (VTS) team a result, an abundant number of coding with RuleWizard for the code review and had two kinds of issues that they searched errors and potential errors passed through coding standards analysis.” for during code reviews in their pursuit of the coding phase. This, in turn, adversely high quality: general coding violations and affected unit and integration tests. After putting Parasoft C/C++test to use, Joel said, “It worked wonders for logical/design errors. Since finding and Due to the high degree of difficulty that detecting the coding violations.” solving coding violations took so much accompanied reviewing all of the source time, the VTS team wanted to automate that code and verifying all of the check points According to Joel, the VTS team cut both portion of the code review process, so they listed in their draft QA plan, Joel Calderon, the time and cost of their code reviews. could focus their manual code reviews on software design supervisor for NSP’s VTS Using Parasoft C/C++test has helped finding logical and design errors.

THE SOLUTION To assist in detecting coding violations, the VTS team used Parasoft C/C++test RuleWizard, which allowed them to cut both the time and cost of their code reviews. Parasoft C/C++test has made it easy to transfer knowledge to new people, reducing the negative impact when experienced developers leave and new ones come in to replace them.
