Comparing as-is and to-be business process diagram

In this page, two Business Process Diagrams are compared: one for modeling the As-is Process and another for modeling the To-be Process. The features of Visual Diff are applied in order to find the differences between them.

  1. In As-Is Process diagram, select Modeling > Visual Diff from the toolbar.
    NOTE: Alternatively, you may right click on diagram background and select Utilities > Visual Diff... from the pop-up menu:

    1 Strategy
    It determines how two diagrams will be compared. Select the appropriate strategy that suits your application most.
    ID
    : Shapes will be matched base on their internal ID. Differences between shapes that have same ID will be displayed in the result pane. This strategy is usually used to visualize the changes of same shapes in two projects.
    Name
    : Shapes will be matched base on their names. This strategy is useful when visualizing differences for external works. One of typical examples is to compare databases and class models.
    Transitor
    : Shapes will be matched base on their transition established by Model Transitor. This way of comparison is usually used to visualize the differences between model elements.
    2 Compare
    It determines how two diagrams will be displayed for comparison.
    All: Both view and model elements are displayed.
    View
    : Differences, such as coordinates, width, height and color of shapes, are displayed.
    Model Element
    : Differences, such as model name, are displayed.
    3 Base
    It determines which diagram is used as a base for comparison.
    Left hand side: Comparison is based on the diagram on the right hand side. For example, if there is a shape absent on the left hand side, but appear on the right hand side, the shape is said to be a new shape.
    Right hand side
    : Comparison is based on the diagram on the right hand side. For example, if there is a shape absent on the left hand side, but appear on the right hand side, the shape is said to be a removed shape.
    4 Filter
    It determines what kind of comparing data will be displayed on the result pane.
    All: Display all kinds of differences including the addition, modification and removal of shapes.
    New: Display only results about the addition of shape and then hide the rest.
    Modified: Display only results about the modification of shapes and then hide the rest.
    Deleted: Display only results about the removal of shapes and then hide the rest.
    5 Filter Model Type... It determines what type of model elements will be shown on the result pane. When Filter Model Type window pops out, uncheck the type of model elements you don't want to be shown; otherwise, check the type of model elements you want it to be shown.
    6 Sort It determines how the result of comparison be displayed on Result pane. You can select sort by Type, by Name or by Change Type.
    Name: All model elements are sorted by their name.
    Change Type: All model elements are changed their type.
    Type:  All model elements are sorted by their type.

    8 Diagram list It lists all diagrams on projects selected in the left hand side and the right hand side respectively.
    9 Use Working Project Check it if you want to select a diagram for comparison within the current working project.
    10 Project Select and open a project directory for comparison.
    11 Diagram Select and open a specific diagram for comparison after selecting a project.
    12 Display pane A pane that has two sides. Each side displays a diagram out of a project.
    13 Result pane The differences of the two projects are shown here. When the word New is shown behind a task that means it is newly added, the word Deleted is shown behind a task that means it is deleted.
    14 Export PDF... Click it to save a document of the two compared diagrams in your computer as PDF.
    15 Launch viewer Open the exported file after you have export a PDF file. Check it to open the PDF file. If you uncheck it, nothing will happen even after you have exported a PDF file.
