Today's business scenario is totally different than what it used to be few years back. OEMs (Original Equipment Manufacturers) today demand a product which is highly stable with negligible issues after commissioning of the product in real field environment. This paper focuses upon the case studies drawn from actual projects being executed at Aricent, which demonstrate how we have achieved excellence in validating the testing phase of the project to meet customer expectations through an internally developed methodology called "4P" approach. Out of the 4Ps (where "P" signifies four performance areas), most important performance area i.e Stability Testing will be covered in detail, using internally developed "Deep Sea" concept. Usage of statistical concepts (e.g Monte Carlo simulation & SPC), prediction suits (e.g NHPP-Gompertz based models), and other mechanism to track the effectiveness of deep sea concept are also covered in this paper.
