Job Task Planning and Organizing
  • Plumbers plan their work in conjunction with forepersons, supervisors and other tradespeople on the job. Time pressures may become intense and interruptions from others result in frequent stops and starts. They reprioritize their tasks to accommodate emergencies and make adjustments to project timelines. Job task planning and organizing differs according to the work context. In the case of residential service appointments, there may be 10 to 15 service calls in one shift. Planning and organizing must take into account the distance between customer locations and the urgency of specific calls. When working on new construction projects, job task planning and organizing is geared towards fitting smoothly into a schedule that involves other trades coming before and after them. Plumbers work both independently and in co-operation with other tradespeople on job sites. (3)
