There are two ways to tell if the timing belt has been replaced. One is obvious-you are looking at a service receipt showing the replacement.
Swimlane diagrams are used whenever you need to show activities, tasks, or process steps which are being performed by different actors/roles. You can use swimlanes to group activities in an activity diagram or process flow by any category what you need: by role, by system, by department, etc.
So, in order to create an efficient swimlane you need to: 1  Determine the lanes. Think over how to divide the process into groups to be represented by swim lanes. 2  Start your diagram. Set the start point of the process. 3  Add a connection. Draw a short arrow if the next action is in the same swim lane.  Add a process.
