Unlike a developer role, a software architect may be involved in delegating tasks to others. You may now be delegating coding tasks to someone else rather than completing them yourself. Depending on how your team is organized, assigning tasks may be more the project manager's responsibility, but a software architect may be involved with management to some degree.
The responsibility for delegating tasks may be a departure from what you are accustomed to as a developer. However, delegation provides you with an opportunity to build trust with your team. A developer will realize that you trust them to perform a task and this responsibility will motivate them to perform at a high level.
