Overview
This course is designed for business analysts, managers, team leads and process owners to provide them with the required competencies for creating use case diagrams and use case scenarios, which serve as a vehicle for eliciting, analyzing, documenting and communicating functional requirements. Delegates will practice creating use cases in the Unified Modeling Language (UML) to graphically represent the interactions between use cases and actors.
Requirements
Experience related to software development or basic technical knowledge is not striclty required but would be beneficial to understand the concepts better.
