Project management encompasses all the activities needed to plan and execute a project: Deciding what needs to be done Estimating costs Ensuring there are suitable people to undertake the project

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

Definition: Design is a problem-solving process whose objective is to find and describe a way: —To implement the system’s functional requirements... —While respecting the constraints imposed by the non-functional requirements... - including the budget

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

The recurring aspects of designs are called design patterns. A pattern is the outline of a reusable solution to a general problem encountered in a particular context Many of them have been systematically documented for all software developersto use

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

The process by which a software engineer learns about the domain to better understand the problem: The domain is the general field of business or technology in which the clients will use the software A domain expert is a person who has a deep knowledge of the domain

Software engineers should avoid re-developing software already developed Types of reuse: Reuse of expertise Reuse of standard designs and algorithms
