What features could help a project manager assign development work for an app effectively?

Subtasks provide a highly effective way for a project manager to assign development work for an app because they break down a larger task into smaller, manageable components. This allows for clearer task delineation and helps team members understand specific responsibilities. By assigning subtasks, the project manager can ensure that all aspects of the overall project are covered and can track progress on each individual piece of work. This granular approach not only clarifies expectations but also enhances accountability among team members, leading to improved efficiency in the development process.

While meetings, comments, and emails can facilitate communication, they do not directly structure or allocate tasks in the same way that subtasks do. Meetings may provide a platform for discussion and coordination, comments can offer feedback, and emails can serve as a means of communication, but they lack the structured assignment and tracking capabilities that subtasks deliver. Thus, subtasks are integral to effective task management in app development projects.
