COAs may have multiple tasks that need to be tracked. The following are the most common tracking methods:

• Units Completed: Useful for tracking tasks that are done repeatedly, where iteration of each unit can easily be measured.
• Incremental Milestones: Used in cases that involve subtasks that need to be completed in an orderly fashion.
• Start to Finish: Focused solely on capturing the starting point and the finishing point of the task and nothing in between.
• Cost Ratio: Usually implemented on a project that has tasks that occur over a long phase or the entire project.
• Improved Performance: Helpful for measuring progress changed against a measurable target.
