Last week's definition: Leadership is not only about having the right attitude to lead but it is also about having a vision and learning goals.
This week's definition: Leaders should posses the right attitude- having the right attitude includes being a visionary leader - which is the ability to lead people towards shared positive dreams - even when things are constantly changing. One of the things constantly changing is group dynamics. Leaders need to be aware of group dynamics.
Group dynamics is the study of group's life. There are different personalities in groups. There are members that work hard towards the shared goal and other who don't participate as much. The reason could be that each group member has different ability. Members may not perform comfortably in all roles. Some group members might be good at something that others are not good at. It is important that leaders are aware of this fact so that they could assign various roles to different members.
I also thought the difference between teams and groups was much clearer from this week's reading.Some of the differences are; in groups there is an assigned leader that carries most of the responsibility but in teams the leader responsibility rotates amongst the group members. In a group the main focus is on the organizational mission as oppose to well defined, specific and unique purpose teams posses. Groups measure effectiveness though performance but teams directly assess teamwork products. In teams individual accountability is high and in teams both individuals and the team as a whole are accountable. In both situations leadership is required but it will vary between groups and teams.
