BA Phase 2 Flashcards
What is Use Case Document?
Use Case document is a documented form of the ‘Use Case’.
It is a written version.
What are important terminologies to be aware of when creating a UC doc?
Actor, Pre-condition, Assumption, Post-condition, Primary flow, Alternative Flow, Exception Flow.
What are actors?
The actor(s) are the parties involved in the UC.
What is pre-condition?
The pre-condition, also called the trigger, is the step that lead directly to the beginning of the use case.
What is assumption(s).
An assumption is simply that - any relevant assumptions taken for the Use Case to be true.
What is post-condition(s)?
The post condition is the possible conclusion to the use case.
What is primary flow?
This section describes the necessary steps needed to be taken to navigate through the ‘Use Case Scenario’.
What is alternative flow?
This sections describes any supplementary actions that can be taken , but are not necessary to, in the Use Case.
What is exception flow?
This section describes any possible errors that may arise at any step throughout the use case.
What is UML?
Unified Modeling language is a visual modeling language used to describe, specify, design, or document business and software processes.
What is the use of UML?
A possible use is modeling business and similar processes.
Another use is analysis, design and implementation of software-based system.
UML in easy words.
UML is a modeling language, not a software development process.
UML is a common language for business analysis, software, architects, and developers to describe, specify, design and document existing or new business processes, structures, and behaviors of software systems.
What is activity diagram?
One of the most common and useful diagram a BA may create is the activity diagram.
It is a simple and intuitive illustration of what happens in a workflow, what activities can be done is parallel and whether there are alternative paths through the workflow.
What is the difference between an activity diagram and a use case document?
Use case documents are the interactions of various actors, activity diagrams are used to depict the processes that occur within a system.
How activity diagram is constructed?
It is constructed from a limited number of shapes i.e. rounded rectangles (represents actions), diamond (represents decision), bars (represents start/end or concurrent activities), A black circle (represents start of initial state), encircled black circle (represents the end/final state).
