We need the ability to assign subtasks while keeping the main task (and all other subtasks) private.
This can be done on Wrike and other platforms.
Use case example:
Main task: Blog Article
Sub-Tasks:
  • Research
  • Writing Article
  • Image Design
  • Layout Design
  • Publish
In this example, I need to assign the writing task to a writer, but he doesn't need to have access to the main task and all the other sub-tasks.
Currently, if we assign someone to a sub-task, they will gain access to the main task and everything in it, including other sub-tasks.
That's a security concern if we work with 3rd party solutions or temporary contractors.
With Wrike, for example, the writer would only get, and see, a writing task. He doesn't even know that this task is a subtask for another task.
