Steps in creating an Activity Diagram for Ecommerce Website.

  • Step 1: Familiarize Activity Diagram Symbols

    Activity Diagram Symbols – are used to create an Activity Diagram which were presented here. Their symbols and applications must be familiarized before you build the Activity Diagram.
    Activity Diagram Symbols
    • Start – is the beginning of the action is symbolized by a filled circle. A dark circle represents the initial node.
    • Action – is a stage of an activity in which users or software accomplish a certain task. Actions are represented by round-edged rectangles.
    • Decision – represent by a diamond and is used to symbolize a conditional branch in the flow. It has two or more outputs and a single input.
    • Swim Lanes – are the lanes drawn as boundaries, and the activities drawn in the same lane as the organization’s activities. Swim lanes must be arranged in a logical order.
    • Activity Flow – is another name for the connectors in the diagram that illustrate the flow between processes (activity).
    • End or Terminator – is the last phase of the activity. An indicated black circle represents the final node.

    Each of these activity diagram symbols shows the overall System behavior. Emphasizing the System’s behavior would be much easier by using these Activity Diagram symbols.

  • Step 2: Determine the targeted users

    After the symbol familiarization, you’ll need to determine your targeted users. Your targeted users will be the ones to use your project.

    Your project is E-commerce Website, then your users would be the admin, sellers and the customers. You may ask them of the common activities that they do when doing task in recognizing faces. These information will help you in proceeding with the next step.

  • Step 3: Analyze the activities included

    Analyzation is very important in creating an activity diagram. It will help you understand the work of the diagram and avoid the unwanted errors.

    The gathered information from the targeted users are very useful in creating an activity diagram. You just need to evaluate these data and pick the general activities.

    From the general activities, you will see the specific activity that are included in it. But only include the useful activities and decisions (circumstances) related to website management. Then you’re ready for the next step.

  • Step 4: Plot the Activity Diagram

    To plot the activity diagram you will need the users, activities, decisions, and their flows (paths). You will base the flow of activities from the evaluated information to have the exact Activity Diagram.

    To plot your Activity diagram, you need to place first the users involved and the process they will perform.

    Then place the figured activities or steps included in doing the process.

    After that, you will trace the flow or path of activities to know the series of interaction between the user/s and the system.

    Finally, you put the swim lanes or the partition in the plotted diagram to separate the objects’ (users and system) activity. This is to identify what are the activities or decisions that are under them or should be performed.


You must know the diagrams used to create and construct the E-Commerce website. because you can’t develop a fully functional system without it. If you develop this activity diagram, you’ll know the actions and situations the system should process and complete. You’ll also identify the needed processes and connect them to other UML diagrams.

By completing Activity Diagrams for every module or per process, you’ll simply accomplish your desired system. The E-Commerce Website activity diagram stays the same as its concept. You may constantly refine and reinvent the idea, but you can’t change its foundation.
