Integrating Methods,ng each technique in a manner to maximize its benefits [53]. It is possible to integrate the use of formal methods with other less formal techniques. Indeed, often, formal methods provide little more than a mathematical notation, perhaps with some tool support. Combining such a notation with a metho
