Unformatted text preview: Ian Sommerville 2000 Software Engineering, 6th edition. Chapter 22 Slide 1 Managing people Managing people working as individuals and in groups Ian Sommerville 2000 Software Engineering, 6th edition. Chapter 22 Slide 2 Objectives To describe simple models of human cognition and their relevance for software managers To explain the key issues that determine the success or otherwise of team working To discuss the problems of selecting and retaining technical staff To introduce the people capability maturity model (P-CMM) Ian Sommerville 2000 Software Engineering, 6th edition. Chapter 22 Slide 3 Topics covered Limits to thinking Group working Choosing and keeping people The people capability maturity model Ian Sommerville 2000 Software Engineering, 6th edition. Chapter 22 Slide 4 People in the process People are an organisations most important assets The tasks of a manager are essentially people oriented. Unless there is some understanding of people, management will be unsuccessful Software engineering is primarily a cognitive activity. Cognitive limitations effectively limit the software process Ian Sommerville 2000 Software Engineering, 6th edition. Chapter 22 Slide 5 Management activities Problem solving (using available people) Motivating (people who work on a project) Planning (what people are going to do) Estimating (how fast people will work) Controlling (people's activities) Organising (the way in which people work) Ian Sommerville 2000 Software Engineering, 6th edition. Chapter 22 Slide 6 Limits to thinking People dont all think the same way but everyone is subject to some basic constraints on their thinking due to Memory organisation Knowledge representation Motivation influences If we understand these constraints, we can understand how they affect people participating in the software process Ian Sommerville 2000 Software Engineering, 6th edition. Chapter 22 Slide 7 Memory organisation Working memory Long-term memory (Large capacity, slow access) Short-term memory From senses Ian Sommerville 2000 Software Engineering, 6th edition. Chapter 22 Slide 8 Short-term memory Fast access, limited capacity 5-7 locations Holds 'chunks' of information where the size of a chunk may vary depending on its familiarity Fast decay time Ian Sommerville 2000 Software Engineering, 6th edition. Chapter 22 Slide 9 Working memory Larger capacity, longer access time Memory area used to integrate information from short-term memory and long-term memory. Relatively fast decay time. Ian Sommerville 2000 Software Engineering, 6th edition. Chapter 22 Slide 10 Long-term memory Slow access, very large capacity Unreliable retrieval mechanism Slow but finite decay time - information needs reinforced Relatively high threshold - work has to be done to get information into long-term memory.
