An activity diagram maker is a tool designed to help you create UML activity diagrams that illustrate the flow of control and steps involved in a system or process. These diagrams are widely used in software development, business process modeling, and other fields to visualize workflows, interactions, and decision points. Whether you’re mapping out a complex system, designing a new process, or documenting an existing one, an activity diagram maker simplifies the creation of clear and professional diagrams, making it easier to communicate and analyze system behavior.

How to Create an Activity Diagram Collaboratively with Your Team?

Set up the Creately workspace to work with your team

Open a Creately workspace and share it with others in your team to collaborate with them. Open the activity diagram shape library or choose a relevant template from the library to work on. Use real-time mouse cursors and synced previews to easily track the changes other participants make in the workspace.

Define the purpose of the activity diagram

The team should agree on the purpose and scope of the diagram, including what process or system is being modeled and what level of detail is required.

Identify the action steps of the system

Gather requirements from all relevant stakeholders and use them to create a list of activities and the flow of control in the process.

Identify the system actors

Identify the various actors in the system and discern how they interact in the system.

Create a flow

List out the order in which actions in a system take place. Identify the conditions that have to be met in order to carry out certain processes, which actions occur at the same time and whether you need to add any branches in the diagram. One or more team members can then collaborate on creating a diagram based on the requirements.

Establish responsibility

Add swimlanes to group activities that are carried out by different actors.

Review and refine the activity diagram online

The team should review the draft diagram and provide feedback on its accuracy and clarity. Use comments threads and @mention comments to discuss changes and tag team members to carry them forward. The diagram should be refined based on this feedback.

Finalize the diagram

Once the team agrees that the diagram accurately represents the process or system, the final version of the diagram can be shared with all stakeholders. You can track each iteration of the diagram with version history and revert back anytime you want. The team can schedule regular review meetings to ensure that the diagram is up-to-date and continues to accurately represent the process or system as it evolves.
