DESCRIPTION (lectures 11 - 12)
Once you have exploded a process on your data flow diagram to a lower level of detail, you need to balance the two levels to ensure completeness and avoid missing processes and data early in the project when it is still cheap to add them. Waiting until later in the process to discover them has proven to be a very expensive endeavor. This KnowledgeKnugget™ introduces a simple but effective method for balancing the levels that automatically reveals overlooked data flows and sometimes even entire processes.
Lectures 11 - 12 answer questions like:
1. What does balancing a Data Flow Diagram mean?
2. What is the business value of balancing?
3. What is the most efficient approach to balancing a DFD?
