Update Task Status For Project Management | AI MVC System Architecture Generator

The Update Task Status use case is commonly seen in project management and collaboration tools. It represents how a team member selects a task, updates its progress, and logs the time spent. With the Sequence Diagram Refinement Tool, this simple flow can be turned into a structured MVC architecture that clearly separates task interface elements, controller actions, and project data management.

Step 1 : Use Case Input

In this example, the topic is about updating the status of a task in a project management system. The use case covers selecting a task, viewing its details, changing its status, and optionally recording time spent on the task.

You may either:

• Enter the use case description manually, or
• Use the “Generate with AI” option to walk through each step in building the description.

Once completed, you can generate both the Controller Class Diagram and the MVC Sequence Diagram with the provided buttons.

Step 2 : Generate MVC Architecture

i. Controller Class Diagram

The tool creates a controller class diagram that models how task-related actions are managed. This diagram is especially useful for clarifying the responsibilities of the controller before diving into sequence-level details.

• Controller Class:
  • UpdateTaskStatusController
  • +handleTaskSelection(taskId)
  • +displayTaskDetails(taskId)
  • +handleStatusSelection(newStatus)
  • +handleTimeEntry(timeSpent)
  • …

You can refine this diagram directly in Visual Paradigm Online or save it for documentation by exporting as SVG.

ii. MVC Sequence Diagram

Based on the use case description, the tool generates an MVC sequence diagram that captures how the user interacts with the task dashboard (View), how the controller processes updates, and how the system records changes in the project database (Model).

From here, you can:

• Export the diagram as SVG for sharing with your team
• Edit the diagram online using Visual Paradigm Online
• Further refine it using the AI Sequence Diagram Refinement Tool
