![]() These dashed lines give clarity on the who's doing what, even for the parallel activities.Important: The UML statechart diagram is not available in Visio 2013 and newer versions. Swimlanes are dashed vertical lines added to the activity diagrams to identify boundaries. Swimlanes in the above activity diagram example are a useful feature. It is important to review and determine what are sequential processes and what are parallel processes.īelow we can see the examples of activity diagram, the example here is the "Employee Review Process".Įnhanced activity diagram (add swimlanes): People tend to think of processes as proceeding in a stepwise fashion. The first cut of the diagram may not have all the parallel processes identified. Repeat until no further changes can be made. For example, while reading e-mail and listening to voice mail can proceed in any order, perhaps both must be complete before a status meeting can be scheduled.ħ. Place a synchronization bar before the process, that is another horizontal bar on the outgoing lines from the parallel processes to "tie" them together as preceding the next sequential process. Consider the processes that come after and identify the process at which the parallel processes all must be complete before the identified process can run.Ħ. In the example below, there are synchronization lines before the activities Receive Project Manager's Package and Receive Employee's Package indicating these follow Process Employee Review but can proceed in parallel.ĥ. A synchronization bar is a horizontal line that connects the incoming lines to the processes for which order is not important. Arrange these side by side and insert a synchronization bar before them. ![]() For example, to start the day, the activities read e-mail and listen to voice mail, can be done in either order.Ĥ. Sometimes activities are encountered whose order is irrelevant, as long as they all get done prior to some other activity. Look for activities whose orders could be switched with no impact on the outcome. Model the activities that proceed sequentially.ģ. Business processes often proceed sequentially, sometimes with conditions (e.g., customer has active account?) deciding which next sequential step to take. Order them in flow chart fashion with decisions and conditional (yes/no type) branching. An activity is a step in a business process, whether the step is done by a person or by a computer, for example, receive shipment.Ģ. Identify activities in the business process. Here are some steps to make an activity diagram:ġ. The main feature of activity diagram is ability to display parallel activities and clear division of 'responsible unit/person' depicted in the process itself. Therefore in process mapping, it is advisable to use Activity Diagram. Typical flow diagram would fail to show these two parallel process. Simple example would be in the fast food restaurant, when the order comes, the kitchen prepares the meal, while the cashier process the payment, these two activities happen almost at the same time but performed by two different persons. Typical process flowchart will only identify sequential activities but rarely elaborate on the parallel process, which we frequently encounter at any organizations. + the sequential and parallel activities in the process. + the organizational unit(s) responsible or functional boundaries of the activities, + the activities within a business process, ![]() Process map will identify the following items: ![]() The clear high level view of the process will help us in further steps in improving and streamlining to achieve efficiency and productivity, which are the ultimate purpose of the BPI. With process mapping we can see how the whole system works in an organization/unit, recognizing which activities generates revenues and costs, along with its stakeholder. Process mapping is undoubtedly an important initial step in the business process improvement effort. ![]()
