AIST3610 StudyChk02 Chapters 3&4

Gary has eight interviews to conduct over the next week. Once he has completed all interviews, he should then write up a summary report. Preparing interview reports prior to completing all interviews will generally be premature until Gary has talked to all interviewees.

False

Generally 'system requirements' are developed in the analysis phase and evolve to more technical 'business requirements' in the design phase.

False

One of the first activities of an analyst is to determine the business requirements for the new system

False

The most common ways to gather information for use cases is the questionnaires of the affected users.

False

The requirements-gathering process is used for building financial support for the project and establishing common understanding of technologies and rapport between the project team building the system and the users of the system.

False

Use cases are always internal and rarely shared or discussed with business users.

False

Use cases are diagrams with three components: selection, process, iteration.

False

Yuri wants to interview both managers and staff in the accounting department for the updated credit analysis project. This is an appropriate group for first round interviews.

False

What are the two requirements analysis strategies that help the team find the most "broken" business processes so that those processes can be redesigned and improved? List them and describe each with a paragrap

Duration-is a detailed examiation of the amount of time it takes to perform a task in a current as-is system. You are basically fixing what is already (i.e. improving) there instead of a complete rebuild. Activity-based costing-examines the cost of each major process or step in a business process rather then the time take.

After working with Chris (who is a staff member in the registrar's office) on major steps in the registration process, Maureen (a systems analyst) will

Create use cases

The second principal part of use cases is 'input and output'. Another name might be:

Data Flows

As a last step in building a use case for the study-abroad registration system, Brianna will

Ask Wendy in the registrar's office to confirm the use case

Barb is an analyst developing a use case. Which of the following will probably NOT be on her use case?

Destination for the major inputs

The authors suggest that an analyst is 'very much like a ____________' and business users are like elusive suspects

Detective

Michael, a systems analyst, is preparing a closed wiki site for Northstate Bank. He has written permission from eight other companies to view their internal wiki sites, and also has approval from his manager and the project team to use these other sites for ideas and structure. This would be a form of

Myles is studying a system to lessen the number of complaints about the Help Desk. He has formally studied the service counter at Wal-Mart, Target and Kohl's department stores; as well as listened in to complaint phone calls to a hotel booking site. He is trying to see how other organizations work at lessening complaints and also how they handle complaints. This would be what type of analysis?

Informal Benchmarking

The Major Steps Performed section on a use case will give the

Information for each step

When gathering requirements, the most commonly used technique is:

Interviews

List the four sub‐types of nonfunctional requirements and describe each with a sentence or two.

Operational-the technical and physical enviroment in which the system operates. Performance- speed, capacity, and reliability. Security-Who has acces to the system and also under what circumstances do they have access. Cultural and political- the legal, political, and cultural requirements that may or may not affect the system

An interview report is prepared in which step of the interview process?

Post interview following-up

Blaine is using a requirements gathering technique that begins with non-threatening questions, avoids abbreviations, groups items into logically coherent sections, and might best be used with outside users. He probably is using

Questionnaires

Marta wants to collect facts and opinions from a wide range of geographically dispersed people quickly and with the least expense. She would probably want to use

Questionnaires

A technique where a set of written (or online) questions are distributed to people (frequently to a large number of people) is

Questionnaires / surveys

After creating the interview report you should

Send a copy to the interviewee with a request to read it and correct or clarify

According to the authors, in moving "from here to there", an analyst needs:

Strong critical thinking skills

Compare structured and unstructured interviews - including when to use, what type of questions are more appropriate, etc.

Structured interviews- are interviews in which the questions have already been pre-determine before the interview even takes place. Typically these would be more close ended questions. Unstructured- is on the fly questions. there are broad, roughly definded set of information that should be learned from the interviewee but the interviewer has free reign on what could or could not be asked

Use cases are used to more fully delineate

System Requirements

An example of a nonfunctional requirement is

System can be used in any of 100 offices worldwide

What are the three requirements analysis strategies that help the team think "outside the box" and are very useful when the team is trying to create completely new ways of accomplishing the business processes? List the m and describe each with a paragraph

Technology analysis-the analysts and managers develop a list of important and interesting technologies. Outcome analysis- focus on understanding the outcomes that provide value to the customer. informal benchmarking-is known as customer facing, it is the processes that interact with the customer

A 'temporal' trigger might be which of the following

Marta has asked the users of a system to picture themselves performing the processes and to write down those processes in a sequential order. She should get a good idea of

Which is NOT true of use cases?

They illustrate what starts (or triggers) an event, all the people that are involved, and how the system provides value.

Omar is an analyst building a use case. Which of the following project roles might be the most important in terms of getting information about building the use case

Users

Use cases generally have three parts:

basic information, inputs and outputs, and details

Probably the first thing to do when conducting an interview is:

build rapport with the interviewee so he or she trusts you

List the five types of requirements introduced in the textbook and describe each with one sentence.

business requirements - come from the statements that describe the reasons for purposing the systems development project. user requirements - written from the perspective of the business during the analysis phase and they focus on what the system needs to do in order to satisfy business user needs. functional requirements - grow and evolve from understanding how the new system can support all the users' needs. Relates directly to a process the system should perform as a part of supporting a user task and/or information it should provide as the user is performing a task. system requirements - come from the other requirements in the design phase that reflect the developer's perspective. They focus on describing how to create the software product that will be produced from the project. nonfunctional requirements - defined as the quality attributes, design, and external interfaces which a product must have. They include very important behavioral properties that the system must have.
