CBAP Exam - Question 267

Question

A software company has won a contract to implement its product for a client. As part of the implementation work, a business analyst (BA) is asked to compile information about the other client applications that will integrate with the new system and provide the information graphically. To establish the boundaries of the new system, the business leaders need to know the interfacing client applications and the type of information that will be exchanged between the existing and new systems.

Which type of diagram should the BA use?

Examice · Accepted Answer

A context diagram is the most appropriate tool for defining the boundaries of the new system and showing interfacing client applications along with the type of information exchanged. It provides a high-level view that helps identify how the system interacts with other external entities, which is essential for business leaders to understand the scope and integration points of the new system.

Kakashi_Sensei · Answer

This answer should be the context diagram. It defines and clarifies the boundaries of system software.

excuse the typo in the previous comment, I meant Sequence

THE right ans is C

B=Sequence
As per Babok pg 341: Sequence diagrams are also often used to show
how user interface components or software components interact.

Pank_HD · Answer

since the need is to 'Define boundaries of system' - which is why we use Data flow diagram viz Level 0 (Context diagram AKA Gane-Sarson Notation).

Context Diagram

Agree. Context

Atzewine · Answer

The business leaders need to know the ''interfacing'' client applications and the ''type of information that will be exchanged''...
The leader needs two elements. Data flow diagram as  context could not help him know type of information. Context diagrams show the system in its entirety, as a transformation engine with externals as the source or consumer of data. A sequence diagram shows how processes or objects interact during a scenario. Sequence diagrams are also often used to showhow user interface components or software components interact.

The ANS is Context. - The Context Diagram shows the system under consideration as a single high-level process and then shows the relationship that the system has with other external entities (systems, organizational groups, external data stores, etc.).

modsjunk · Answer

Ans is context
From BABOK Page 253 - KEYWORD SCOPE OF A SYSTEM

Are excellent ways to define the scope of a system and all of the systems,
interfaces, and user interfaces that attach to it. Allows for estimation of the
effort needed to study the work.

saeedddddd · Answer

sorry , i was wrong it's context

UppersquareCapital · Answer

Ans - Sequence Diagram. It shows how processes or objects interact (including user interface and software components) during a scenario.

Yichun · Answer

10.42 Sequence Diagrams
10.42.1 purpose - mentioned info passed between objects in the system, not between systems
Sequence diagrams are used to model the logic of usage scenarios by showing
the information passed between objects in the system through the execution of
the scenario.

fepecy · Answer

Ans. C BABOK V.3 Context Diagrams help specify and model requirements by illustrating the flow of information in a visual way to
stakeholders and solution professionals. Secondly, because a context diagram describes the entire system in context (we get to define the BOUNDARIES of that system) and how it exchanges information with other external systems (..the interfacing client applications and the type of information that will be exchanged between the existing and new systems).

[Removed] · Answer

D: If we look at the Strengths of the Data Flow technique, we can see:
1. Are excellent ways to define the scope of a system and all of the systems,
interfaces, and user interfaces that attach to it
2. Illustrates connections to other systems
2. Helps define the boundaries of a system

Sequence is technical diagram

NorieRose · Answer

Context Diagram

Rabbitsfoot · Answer

D: Context Diagram
While sequence diagrams are valuable for illustrating the flow of interactions and control between objects, they may not be the most suitable tool for explicitly capturing the types or specifics of information exchanged between systems. (check the question) Other documentation or modeling techniques, such as data flow diagrams (context diagram) or interface specifications, may be better suited for representing this aspect of system integration requirements.
