2.4 Oral and written communication Humans use language to communicate. This is an obvious statement, but what is language and how do we use it? Language is basically a set of symbols with associated meanings. These symbols are delivered using a set of rules for stringing the symbols together to generate additional meaning. Humans use mostly sounds to represent these symbols, although as an Italian I can communicate common meanings by only using a range of hand gestures! We string together phonetic sounds to make words, and we

1.3 Activities Activity 2A sets the scene by focusing on the ‘big picture’ where you will be asked to choose between four alternative visions of the future. This activity radically shifts the scale of investigation from the personal to the global. However, as with all Author(s):
1.2 Readings In considering the environmental and social challenges that we are currently facing, we are clearly dealing with so-called ‘wicked’ problems: the ‘problems’ manifest themselves only as you try to engage and Author(s):
Learning outcomes After studying this unit you should be able to: evaluate a specific example or case of a product development process in terms of the ‘waterfall’ life cycle model of software development; classify new product developments as: fault correction, enhancements, new but similar products, radically different, revolutionary or iconoclastic products; analyse the causes of a systems failure; identify and evaluate the importance of the

Are you always the quiet one when it comes to group discussion? This unit will help you improve your working relationships with other people in groups of three or more. This unit also deals with project life cycles, project management and the role of the leader.
4.1 Beginnings Systems engineering has its roots in three linked strands of thinking: the concepts of systems science, engineering and public policy problem resolution. The first of these can be traced back to the work of von Bertalanffy (1968, pp. 8–15, 96–98) and others during the 1920s and 1930s but received a significant impetus when, in 1954, the Society for General Systems Theory was established at the annual meeting of the American Association for the Advancement of Science. The society later cha
