Step 2: Job Task Breakdown. Each job must be broken down into a clearly defined sequence of individual tasks. Avoid defining individual job tasks too narrowly or too broadly; generally speaking, a job should contain no more than 10 individual tasks. Jobs that exceed this number should be separated into two or more separate phases.
