Exam 11: Managing Systems Implementation

Parallel operation is the least costly changeover method. _________________________

Effective online documentation is an important productivity tool because it empowers users and reduces the time that IT staff members must spend in providing telephone, e-mail, or face-to-face assistance.

Libby mentions that she must test a program that interacts with other programs, and she wants to begin by testing the program individually. Emma tells her about a process in which a programmer simulates each program outcome or result and displays a message to indicate whether or not the program executed successfully. What is the name of this process?

If one module refers to internal logic contained in another module, the modules are loosely coupled. _________________________

In a structure chart, a control couple shows a message, also called a status ____, which one module sends to another.

-As the accompanying figure illustrates, the ____ changeover method requires that both the old and the new information systems operate fully for a specific period.

Replacement code for applications is sometimes referred to as ____________________.

An old system might be capable of ____________________ data in an acceptable format for a new system or in a standard format, such as ASCII or ODBC.

To draw a structure chart, working from a logical model the systems analyst transforms program modules into functional primitives and object methods.

Modules that are independent are tightly coupled. _________________________

In a structure chart, a(n) ____ line, which has a diamond on one end, indicates that a control module determines which subordinate modules will be invoked.

A module that performs a single function or task has a high degree of ____, which is desirable.

-When evaluating a system, which of the following is not necessary for a systems analyst to do?

A class diagram includes the class ____, which describe the characteristics of objects in the class.

Compiling a program using a CASE tool or a language compiler detects syntax errors, which are language grammar errors.

The skill set required to develop documentation usually is the same as that to develop a system.

During ____________________, existing data is loaded into the new system.

MATCHING Identify the letter of the choice that best matches the phrase or definition.a.training plan f.pseudocode b.status flag g.operational c.control h.top-down d.parallel i.phased e.release plan j.data conversion -In a structure chart, typically this kind of module directs lower-level modules.

____ describes the degree of interdependence among modules.

-A(n) ____________________, such as that illustrated in the accompanying figure, consists of rectangles that represent the program modules, with arrows and other symbols that provide additional information.
