Carlos has been a team leader for three years. As a team leader, he spends a considerable amount of his time performing, as he sees it$,$ about

four to five types of functions in support of his team members. This morning he spent two hours in budget hearings and another hour meeting

with a vendor of an important component and engineering. His team had discovered the problem yesterday and knows it's a critical aspect to the

product. On a typical day scenario, he will spend about $30$ percent of his day contending with influences from groups both inside and outside the

company. This afternoon he is scheduled to meet with the team for two hours to consider the vendor's solution offered this morning at the

meeting with engineering. Later in the afternoon, he will be mediating a dispute between three team members who are bickering about overtime

assignments. The rest of the time, Carlos visits employees at their work area as he walks to or from a meeting, or when he goes out to the floor

to "chat" about the day or a change order in tomorrow's shop schedule.
