Synopsis
As a fundamental component to identifying requirements for a new system, business analysts must be able to illustrate how "actors", such as end users, stakeholders, or related systems, will be affected once the new system is implemented. This process, also known as Use Case Modelling, provides business analysts with a powerful tool for documenting functional requirements - and the interactions between these requirements - in a manner that can be easily communicated to designers, programmers, project manager and other project stakeholders.
This course provides business analysts with the required competencies for creating use case diagrams and use case scenarios, which serve as a vehicle for eliciting, analysing, documenting and communicating functional requirements. Delegates will practice creating use cases in the Unified Modelling Language (UML) to graphically represent the interactions between use cases and actors. To fully gain the benefits of UML, use case diagrams are created through an object-oriented approach, which enables business analysts to sift through the complexity of a system by breaking it down into smaller units.
Attendees of this course will gain more than just the lexicon required for use case and object oriented modelling. Through interactive exercises, they will practice writing the alternate/exception flows, arranging objects into properly named classes and reading class diagrams and most importantly, gain the ability to integrate use case modelling within the software development lifecycle to ensure that project requirements are accurate, complete and map to the objectives of the business.
Reminder: Prior to taking this course, delegates should have acquired the background as taught in Eliciting and Managing Requirements and Business Process Modeling.
