Value chain model


The value chain is a powerful strategic tool that organizations can use to stay competitive and focus efforts efficiently towards their line of business.

With Bizagi Modeler you can diagram your corporate value chain and analyze every step required to create core products or services, identify how to increase the efficiency of your chain as a whole, and create a competitive advantage.


The following image illustrates the value chain concept as suggested by Michael Porter:




Value chain basics

The main objective in a diagrammed value chain, is to help you perform an analysis that leads to identifying and representing the strategic or primary activities for your organization.

In a value chain you often find depicted: primary activities, support activities, and inputs which go through primary activities to add value (margin or generally, output).

Additionally, though there is no explicit delimiter for a group of activities, grouping them provides a better legibility and maintainability,  especially when you are editing the value chain definition.


Before you start

This feature is available when directly accessing the Process Library

It is displayed for both, editors and contributors, though only editors may create value chain diagrams.


To define your corporate value chain, log in to your workspace at

Alternatively, you can access your workspace by clicking the Process Library option found on the ribbon:




Value chain diagrams are not displayed in the desktop application.


Defining the value chain

To define the value chain of your corporation, hover the mouse pointer on Plus_icon:




Switch to the Create value chain diagram icon and click it:




Give a name and description to your value chain diagram, and click Save:




A new diagram appears which already features a template with the layout and groups as often used in a value chain definition. Note that the value chain model is opened in editable mode and checked out to you:




The template contains three groups which may each hold any number of processes.

Refer to the options depicted and described below, to start defining your value chain:








Label this group

Click the default Enter group name text and specify how you want this group to be labeled.


Add new support process

Click the ValueChain_icon3 icon to add a new support process. While modeling with Bizagi Modeler, you see this as a process (equivalent to Porter's activity definition) since it can encompass a set of finer-grained (i.e sub-activities).

Support processes are represented as rectangles:




Label this process

Click the default Enter process name text and specify how you want this process to be labeled.


Link a process diagram

Click ValueChain_icon6 to display a pop-up where you can select a specific process diagram in your workspace.

To create a hyperlink so the process is bound to the definition in the selected process diagram, as described at Linking a process in the value chain.


Reorder this process

Click the ValueChain_icon8 or ValueChain_icon9 icons to move each process to the right or left.


Label this Input / output

Click the default Enter inputs text (for the left-side shape depicting inputs), or the Enter Outputs text (for the right-side shape depicting outputs) to specify the label you want.


Add new primary / strategic group

Click the ValueChain_icon10 icon to include a new primary / strategic group within the main primary group.


Add new primary / strategic process

Click the ValueChain_icon11 icon to include a new primary / strategic process. While modeling with Bizagi Modeler, you see this as a process (equivalent to Porter's activity definition) since it can include in turn a set of finer-grained sub-activities.

Primary / strategic processes are represented a chevron shape:




Reorder primary / strategic group

Click the ValueChain_icon12 or ValueChain_icon13 icons, to move each primary group to the bottom or top.


Delete this item

Click the ValueChain_icon7 icon deletes the element you are hovering the mouse pointer over.

This icon is available for groups and both types of processes.

When you delete a group which contains processes inside, you will need to confirm that you are aware about deleting its contents:




If you have deleted one of the major elements of the default template, such as the top or bottom groups, or the inputs or outputs definition, you can include them back:

Click ValueChain_icon15 to include either the top or bottom group.

Click ValueChain_icon14  to include the inputs or outputs definition.


Save the changes in your model by clicking Save located in the ribbon.




Once you are done, click Check In to release the diagrams for other users:




A window appears to let you choose whether to save your changes as a new revision or not. To create the revision select Save revision and enter a description of the changes you made.




To view examples of value chain diagrams, refer to Value chain examples.


Editing the value chain model

Users can open value chain models stored in the cloud repository, and edit them as they require.

To edit a value chain model:


1. Open your model and select the value chain diagram to edit.

Make sure the diagram is not checked in by any other user.




2. In the Ribbon, click Check Out. Once you click this button, the diagram is locked for editing. No other users can make changes to it until you check it back in.




3. Edit your value chain model.


4. Once you finish your edits, release the model by clicking Check In. The model will be released to other editors to perform changes.




Editing the properties of the value chain model

You can select a diagrammed value chain and rename it or delete it. This options are available only when the diagram is not checked out by you or any other user.
