Therefore:
Work products and outcomes appear vertically.
Work processes and steps appear horizontally.
Note: Where tasks are organized in a logical or chronological sequence, the major steps appear vertically (the tasks become the major steps involved in the function to be carried out). The steps involved in carrying out each task should not be confused with the major steps involved in the job function.
Analysis process for the units of work
Specify and define the scope of the job function, the occupation or the trade.
Describe the outcomes of the work: tasks.
For one of the tasks, describe the phases involved in performing the task, the work steps and the work process: operations.
For one of the operations, describe the substeps and the elements and details of the work: the suboperations.
Verify the degree of precision required for a series of units along the horizontal axis, referring to Table 4, Units of Work.
