The Quality and Security of an Open Source Software is often challenged ” If it is free, how good it can be?” Today, Open Source Software is used in mission critical real world applications in lot of organisation and governments, and at RAAL Systems, we have proven quality process of “Defect Detection”, Defect Verification” and “Solution Verification”, which is reviewed and tested to ensure the new code does not create a new defect. The solutions that are implemented are assessed for their functional and structural quality and conforms to a given design, based on functional requirement and specification as well as meets non-functional requirements that meets delivery of functional requirements.
