While defining the problem, the BA will require to couple quantitative analysiswith strategic thinking in order to arrive at the way of approach to solution.While staffing the team, one must remember that it is not necessary for the entire team to be present at onelocation.

with all sub-teams forms an important part for everyone to stay in the same page. Another task of the BAwould involve getting an heads-up from different teams in different time zones. Also while leaving for the day;they would have to inform the next set of duties for the team in a different geographic location. This show whybeing able to work in a team and proper communication is some of the required key skills in a BA.A BA distills his discoveries into solutions creating an impact in the way the client organization will functionfrom now on. A simple example of the role of the business analyst could be in the task of cost cutting. In thecurrent economy, many organizations and firms would have implemented cost cutting in theirbusinessmodels in order to survive the bad times. A BA is the one who identifies the issues (in this case, the extravagantexpenditures), forms various hypotheses and analyses, distill their conclusions into recommendations andpresent it to the client management who will incorporate that into their business. A BA could either workclosely at the client side or at the parent organization, but in any case his job would be to get as muchinformation about existing systems from the client, have brainstorming sessions with team to input ideas andhelp build effective solutions.88. What is a Communication Diagram?A UML 2.0 Communication Diagram models the objects or parts of a system, the interactions (or messages)between them, and the sequence in which these interactions occur. There are a lot of similarities betweencommunication diagrams and sequence diagrams in terms of the information they show, but because of howeach diagram presents the information, one diagram may be better at conveying or emphasizing specificinformation over the other.Communication diagrams use a free-form arrangement of objects or parts of a system. This can be comparedto how classes and objects are laid out in UML class and object diagrams. Then the interactions between theobjects or parts of the system are show and labeled to indicate the chronological sequence in which they occur.The free-form arrangement of objects lends itself wekk to showing the sequenced interactions in a morecompact space, allowing the analyst to place objects that have the highest number of interactions with eachother near one another. This is the advantage of the communication diagram over the sequence diagram.
As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
