Philips Company Restricted Information and Software Technology MG-R: a Component Based Software Architecture for CE Products Solution: Use Subsystems Products (configurations) Subsystems or Standard designs (deployment) Basic components (assembly) Advantages:  Hide low-level assembly complexity from product creators  Concentrate domain knowledge (TV, Txt, UI) in capability centres Is a subsystem a component? Yes and no (see later)!
