An organizational risk is a risk that is rooted in a company's culture. What is technological risk? A technological risk is a risk that occurs due to new or unfamiliar technology. A resources risk is a risk rooted in the technical aptitude, skills, and availability of staff. What is a deployment risk? A deployment risk is a risk rooted in schedule and timeline issues. How is Return on Investment calculated? Sum of net present values and costs. How is Net Present Value calculated? P / (1 + i)^t How is break-even point calculated? Take the absolute value of the ending value of the last year in the red, divide by the sum of the absolute values of the first year in the black AND the first year in the red, and multiply that by 365. How is discount factor calculated? Discount factor takes a look at the interest (let's say 0.05), Add 1 to the interest, making 1.05, and take it to the
power of the current period (1/05^2, etc). Finally divide that by 1. Which of the following is a general guideline for designing navigation visibility? a.

Navigation visibility is a design principle in which one object has a reference to another object, and can interact with it. Which of the following is true of class-level methods? They are executed by the class instead of a specific object of the class. A class named SaleItem
which has methods to calculate its own price is said to have good ______. Domain layer classes should ____. prepare persistent classes for storage to the database Data access layer classes should ____. contain Structure Query Language (SQL) statements All ____ in a table are guaranteed to be unique if the table's primary key is guaranteed to be unique. Determine the major subsystems and assigning them to an iteration is done in which Core Process? T/F: Textual models are used to represent precise aspects of the system that can be best represented by using formulas. T/F: Sometimes the activities within Core Process one are completed before the actual project starts. T/F: The analyst begins identifying state events by asking about the specific deadlines that the system must accommodate. T/F: A loop frame and an asterisk mean the same thing in a sequence diagram. T/F: Activity diagrams cannot be used to describe processes that involve automated system activities. T/F: The output of the design activities is a set of diagrams and documents that describe the solution system. T/F: A project cannot have both predictive and adaptive elements. T/F: The activation lifeline is depicted by a vertical dashed line under an object. T/F: The first-cut sequence diagram contains view layer and business layer. T/F: The final decision of project scope in an Agile project rests with the users. One way to show concurrent paths within an activity diagram is with a _____. A(n) _____ is something that occurs at a specific time and place and can be precisely measured The _____ technique is a technique to identify use cases by determining specific goals or objectives must be completed by a user.
