tasks can be clearly identified in the architectural blueprint, enabling project team members to position their tasks well. A good architectural blueprint can also standardize tasks, which can be well divided into categories, with the same or similar workload and nature of tasks in the same class. This is a very good basis for estimating the workload.Operation and MaintenancePreviously said that each task in the frame composition has a better positioning. Anyone can use it to quickly familiariz
