Process Engineering Using Business and System Use Cases

Business Analysis

BA706 | Length: 1 day


Unified Modeling Language-based Use Cases are an indispensable tool in understanding the context and functionality of both manual and automated business processes. While the UML focuses on the automated segment of the business system, business requirements practitioners have expanded the scope of use cases through the development of best practices for the total business solution through business use cases.

Objectives and Outcomes

In this course, you will learn how to:

  • Model and diagram business processes in a manner that correctly positions automated systems within the total business solution context.
  • Vet manual and automated as-is and to-be business processes for efficacy and efficiency in the production of business deliverables and desired outcomes.
  • Leverage use case artifacts towards the creation of in-built quality metrics and the accelerated development of test scenarios.
