PL.05 Specify Tasks Context To develop a quality work package each separate Task, and each outcome required for each Task, must be specified. A Task is a separately schedulable component of the work package, i.e. a component that may be have different scheduling criteria from other components of the work. These may include a different time of execution or different types or levels of resources. For example, replacing a faulty pipe spool may have 3 Tasks identified:  Field measure the existing pipe spool to determine critical dimensions to provide a fabrication drawing.  Manufacture the pipe spool as per the drawing.  Install the new pipe spool in place of the faulty pipe spool. Each of these Tasks will likely have a different time of execution and different types or levels of resources. A task may involve only a single outcome or may require a number of sub outcomes to be achieved. An outcome is a condition or state that must be achieved in the process of completing the work to the standard required. If it is important that something be achieved during the work, then it is an outcome. If it is important how something be achieved during the work, then a work procedure is required. For example, repairing a crack in a steel component may require the following outcomes and specifications:  Test with dye penetrant to define the location and length of the crack,  Grind out all of the indicated crack length + 25mm at each end;  Test with dye penetrant to confirm that the crack has been ground out,  Clean the ground surface with XXX.  Fill weld the ground area with YYY.  Grind the finished weld flat with the original component surface. For example, crushing of ore feed prior to the grinding circuit may require the following outcomes and specifications:

 Set apron feeder to achieve a feed of 200tph.  Run CV01at the speed to achieve no spillage.  Set crusher gap to achieve 50mm product sizing.  Operate crusher in a choke feed state.

Therefore, if a component of the work has different scheduling parameters a separate Task must be created for it. Each outcome that is necessary for the Task must be specified. Purpose To specify all Tasks necessary for scheduling the work package.
