These two models are kept separate, but the approach fully records their ongoing and changing interrelationships. This feature is missing from virtually all other system and software development methods and from CASE tools that only automate the requirements model.\u003cbr\u003e \u003cbr\u003eSystem managers, system architects, system engineers, and managers and engineers in all of the diverse engineering technologies will benefit from this comprehensive, pragmatic text. In addition to its models of requirements and architecture and of the development process itself, the book uses in-depth case studies of a hospital monitoring system and of a multidisciplinary groundwater analysis system to illustrate the principles.\u003cbr\u003e \u003cbr\u003eCompatibility Between the H\/H\/P Methods and the UML:\u003cbr\u003e \u003cbr\u003eThe Hatley\/Pirbhai architecture and requirements methods—described in \u003ci\u003eStrategies for Real-Time System Specification\u003c\/i\u003e—have been widely used for almost two decades in system and software development. Now known as the Hatley\/Hruschka\/Pirbhai (H\/H\/P) methods, they have always been compatible with object-oriented software techniques, such as the UML, by defining architectural elements as classes, objects, messages, inheritance relationships, and so on. In\u003ci\u003e \u003cb\u003e Process for System Architecture and Requirements Engineering,\u003c\/b\u003e \u003c\/i\u003e that compatibility is made more specific through the addition of message diagrams, inheritance diagrams, and new notations that go with them. In addition, state charts, while never excluded, are now specifically included as a representation of sequential machines.\u003cbr\u003e \u003cbr\u003eThese additions make definition of the system\/software boundary even more straightforward, while retaining the clear separation of requirements and design at the system levels that is a hallmark of the H\/H\/P methods—not shared by most OO techniques. Once the transition to software is made, the developer is free to continue using the H\/H\/P methods, or to use the UML or any other software-specific technique.","brand":"Pearson Education","offers":[{"title":"Default Title","offer_id":47078952599792,"sku":"9780133488548","price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780133488548_p0.jpg?v=1763641115","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780133488548","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
