Interaction diagrams are used to model the dynamic aspects of a software system They help you to visualize how the system runs. An interaction diagram is often built from a use case and a class diagram. —The objective is to show how a set of objects accomplish the required interactions with an actor

10.1 Basic definitions A failure is an unacceptable behaviour exhibited by a system —The frequency of failures measures the reliability —An important design objective is to achieve a very low failure rate and hence high reliability. —A failure can result from a violation of an explicit or implicit requirement

The Unified Modelling Language is a standard graphical language for modelling object oriented software At the end of the 1980s and the beginning of 1990s, the first object￾oriented development processes appeared The proliferation of methods and notations tended to cause

Interactive Complexity Complexity is a moving target The underlying factor is intellectual manageability 1. A simple\system has a small number of unknowns in its interactions within the system and with its environment 2. A system is intellectually unmanageable when the level of interactions reaches the point where they cannot be thoroughly
