Oak Systems, a software verification company based in Bengaluru, has been engaged to perform independent verification and validation (IV&V) for an Advanced Lightweight Torpedo (ALWT) developed by a naval research lab. The project involved reviewing over 50 documents, ensuring compliance with IEEE standards, and addressing challenges such as the absence of processes and lack of tool usage skills. A team of 3 to 10 engineers conducted the work over 100 person-months, discovering over 1,000 major defects in the software.
