The application entity diagram can be viewed as an initial entity-relationship diagram that does not detail the attributes associated with each entity or specify the cardinality of the relationships. Key objectives of this first phase include establishing a clear boundary for the proposed application or system and identifying the application’s internal and external entities. Next, the system’s major functions (the tasks or processes the system must perform) are defined and translated into measurable system objectives.

Object-oriented software is often less efficient than structured software on traditional single-processor computers. Note, however, that object-oriented software may actually be more efficient on the parallel systems that are evolving. More significantly, relatively few programmers are trained in the object-oriented approach, leading to personnel shortages, and adding to software development expense. Current academic curricula are beginning to stress object-oriented software, however, so this problem may grow less severe given time.

Managing and/or controlling the amount of data created by the structured analysis and design methodology can be time-consuming. Maintaining, updating, and documenting a complete set of data flow diagrams and a complete data dictionary are significant data management tasks in their own right. The step-by-step design philosophy makes this methodology inflexible. System and data requirements must be frozen at the beginning of the life cycle, so the actual systems developed may not reflect the current data and system requirements.
