Requirements Engineering Workshop with Use Cases

Requirements Engineering Workshop with Use Cases, – Model-Based Requirements Engineering with Use Case

Requirements Engineering Workshop with Use Cases, Use Cases describe possible interactions involving a system and its environment. Use Cases are considered as great tools and effective means for operational and functional requirements elicitation and analysis.

Requirements Engineering Workshop with Use Cases informal definitions of use cases in the analysis process. We present an approach supported by any tool for use cases based requirements engineering and management.

Requirements engineering process based on use cases  provide promising solutions concerning the early high-level requirements gathering problem dealing with system operation and ConOps:

• One of the primary challenges in a system design process is the ability to elicit the correct and necessary system requirements from the stakeholders and specify them in a manner understandable to them so those requirements can be verified and validated.
• Data and process models, prototypes, requirement specifications.
• Understood by designers but not by users.
• Leads to scope creep, schedule creep, cost overruns.

Requirements Engineering Workshop with Use Cases drives the development of a system by understanding how the system will be used and then helping systems engineers and project managers  for an appropriate system to support the users.

Learn how to drive agile projects using use cases in Requirements Engineering Workshop with Use Cases training course.  All the delegates will model use cases and system validation cases in the beginning of the workshop.

A use case is a description of normal and abnormal conditions and step-by-step,  interactions between a system and actors in its environment.

A use case model includes:

• Use case description
• Actors
• Relationships
• A relationship between an actor and a use case captures the fact that the actor participates in the use case.
•  A use case diagram shows use case names, pre and post conditions, actors, relationships between actors and use cases, and relationships between use cases.
• Include and extend relationship

Successful development of systems and software systems depends on the quality of the requirements and requirements engineering process. Use cases and operational scenarios are promising tools for identifying, eliciting, analyzing, specifying and validating requirements. The role of use case modeling in requirements engineering and its relation to system verification and validation, plays a big role in Requirements Engineering Workshop with Use Cases.  The workshop covers the concepts and representations in use case modeling. Semantic issues are described and illustrated and notations based on natural and graphical languages are provided.
