11、on based on:Basic needs(e.g.food,sleep,etc.);Personal needs(e.g.respect,self-esteem);Social needs(e.g.to be accepted as part of a group).Ian Sommerville 2004Software Engineering,7th edition.Chapter 25 Slide 13Human needs hierarchyIan Sommerville 2004Software Engineering,7th edition.Chapter 25 Slide

13、an Sommerville 2004Software Engineering,7th edition.Chapter 25 Slide 16Personality typeslThe needs hierarchy is almost certainly an over-simplification of motivation in practice.lMotivation should also take into account different personality types:Task-oriented;Self-oriented;Interaction-oriented.Ian
14、 Sommerville 2004Software Engineering,7th edition.Chapter 25 Slide 17Personality typeslTask-oriented.The motivation for doing the work is the work itself;lSelf-oriented.The work is a means to an end which is the achievement of individual goals-e.g.to get rich,to play tennis,to travel etc.;lInteracti
15、on-orientedThe principal motivation is the presence and actions of co-workers.People go to work because they like to go to work.Ian Sommerville 2004Software Engineering,7th edition.Chapter 25 Slide 18Motivation balancelIndividual motivations are made up of elements of each class.lThe balance can cha
16、nge depending on personal circumstances and external events.lHowever,people are not just motivated by personal factors but also by being part of a group and culture.lPeople go to work because they are motivated by the people that they work with.Ian Sommerville 2004Software Engineering,7th edition.Ch
17、apter 25 Slide 19Managing groupslMost software engineering is a group activityThe development schedule for most non-trivial software projects is such that they cannot be completed by one person working alone.lGroup interaction is a key determinant of group performance.lFlexibility in group compositi

19、 edition.Chapter 25 Slide 21Group compositionlGroup composed of members who share the same motivation can be problematicTask-oriented-everyone wants to do their own thing;Self-oriented-everyone wants to be the boss;Interaction-oriented-too much chatting,not enough work.lAn effective group has a bala
20、nce of all types.lThis can be difficult to achieve software engineers are often task-oriented.lInteraction-oriented people are very important as they can detect and defuse tensions that arise.Ian Sommerville 2004Software Engineering,7th edition.Chapter 25 Slide 22Group compositionIan Sommerville 200

22、Chapter 25 Slide 24Group cohesivenesslIn a cohesive group,members consider the group to be more important than any individual in it.lThe advantages of a cohesive group are:Group quality standards can be developed;Group members work closely together so inhibitions caused by ignorance are reduced;Team
23、 members learn from each other and get to know each others work;Egoless programming where members strive to improve each others programs can be practised.Ian Sommerville 2004Software Engineering,7th edition.Chapter 25 Slide 25Team spiritIan Sommerville 2004Software Engineering,7th edition.Chapter 25
24、 Slide 26Developing cohesivenesslCohesiveness is influenced by factors such as the organisational culture and the personalities in the group.lCohesiveness can be encouraged throughSocial events;Developing a group identity and territory;Explicit team-building activities.lOpenness with information is
25、a simple way of ensuring all group members feel part of the group.Ian Sommerville 2004Software Engineering,7th edition.Chapter 25 Slide 27lGroup members tend to be loyal to cohesive groups.lGroupthink is preservation of group irrespective of technical or organizational considerations.lManagement sho
26、uld act positively to avoid groupthink by forcing external involvement with each group.Group loyaltiesIan Sommerville 2004Software Engineering,7th edition.Chapter 25 Slide 28Group communicationslGood communications are essential for effective group working.lInformation must be exchanged on the statu
27、s of work,design decisions and changes to previous decisions.lGood communications also strengthens group cohesion as it promotes understanding.Ian Sommerville 2004Software Engineering,7th edition.Chapter 25 Slide 29lGroup sizeThe larger the group,the harder it is for people to communicate with other
28、 group members.lGroup structureCommunication is better in informally structured groups than in hierarchically structured groups.lGroup compositionCommunication is better when there are different personality types in a group and when groups are mixed rather than single sex.lThe physical work environm
29、entGood workplace organisation can help encourage communications.Group communicationsIan Sommerville 2004Software Engineering,7th edition.Chapter 25 Slide 30Group organisationlSmall software engineering groups are usually organised informally without a rigid structure.lFor large projects,there may b
30、e a hierarchical structure where different groups are responsible for different sub-projects.Ian Sommerville 2004Software Engineering,7th edition.Chapter 25 Slide 31Informal groupslThe group acts as a whole and comes to a consensus on decisions affecting the system.lThe group leader serves as the ex
31、ternal interface of the group but does not allocate specific work items.lRather,work is discussed by the group as a whole and tasks are allocated according to ability and experience.lThis approach is successful for groups where all members are experienced and competent.Ian Sommerville 2004Software E
32、ngineering,7th edition.Chapter 25 Slide 32Extreme programming groupslExtreme programming groups are variants of an informal,democratic organisation.lIn extreme programming groups,some management decisions are devolved to group members.lProgrammers work in pairs and take a collective responsibility f
33、or code that is developed.Ian Sommerville 2004Software Engineering,7th edition.Chapter 25 Slide 33Chief programmer teamslConsist of a kernel of specialists helped by others added to the project as required.lThe motivation behind their development is the wide difference in ability in different progra
34、mmers.lChief programmer teams provide a supporting environment for very able programmers to be responsible for most of the system development.Ian Sommerville 2004Software Engineering,7th edition.Chapter 25 Slide 34Problems lThis chief programmer approach,in different forms,has been successful in som
35、e settings.lHowever,it suffers from a number of problemsTalented designers and programmers are hard to find.Without exceptional people in these roles,the approach will fail;Other group members may resent the chief programmer taking the credit for success so may deliberately undermine his/her role;Th
36、ere is a high project risk as the project will fail if both the chief and deputy programmer are unavailable.The organisational structures and grades in a company may be unable to accommodate this type of group.Ian Sommerville 2004Software Engineering,7th edition.Chapter 25 Slide 35lThe physical work
