4. Workflow analysis tends to focus most strongly on: (Points: 1)
the people who perform the work.
the policies influencing decision making.
the actual work or tasks being completed.
the data used within the system.
The creation of a design prototype that is not a working information system, but represents a part of the system that needs additional refinement happens with the prototyping methodology.
1. The primary advantage of the Waterfall Development methodology is requirements are completely specified and held relatively constant prior to programming.

Prepare the interviewee.
9. The biggest difference between collecting data by questionnaire or by interview is: (Points: 1)
questionnaires are easier and faster to design, administer, and analyze than are interviews.
questions on questionnaires cannot be open-ended; interviews can include open-ended questions.

Prepare appropriate scales, checklists, and other materials for conducting the observations.

Data flow diagrams are not able to be easily understood by users.
The diagrams are an excellent way to represent the system graphically without committing to a specific technical implementation.
Data flow diagrams represent systems only in extremely simple terms.

estimate the hours and request deliverables
identify the tasks and estimate the time needed to complete them
initiate the project and create the project management assessment
make tradeoffs and set conservative numbers
timebox the completion date
The process of assigning values for the time and effort needed to perform a system project is called _____.
Kathryn has little experience estimating the time it will take to complete a systems project. She has just completed the planning phase of the project. What method should she use to estimate the time required to build the system?
adjusted project complexity
more complex approach
A(n) ____________ is a measure of program size based on the number and complexity of inputs, outputs, queries, files, and program interfaces.
line of code
Root cause analysis attempts to find solutions for the business problems.
A systems analyst is participating in an exchange of services with another organization. First, the analyst visits the partner organization, studies and evaluates their systems, and recommends changes and improvements. Then, a team of analysts from the partner organization visits the analyst's organization and performs the same service. This process is an example of benchmarking.
What information-gathering strategy enables the analyst to see the reality of the situation rather than listen to others describe it?
joint application design (JAD) sessions
The information gathering technique that is most effective in combining information from a variety of perspectives, building consensus, and resolving discrepancies is a(n) _____.
joint application development
Which of the following analysis strategies incurs the highest risk yet has the potential to provide high value to the business?

Business Process Improvement
Business Process Reengineering
Business Process Renovation
