Implementation Process

-Acquisition of hardware, software and services -Software development or modification -Data conversion -End-user training -Conversion (Parallel, Pilot, phased, Plunge)

Control measures for end user applications vary greatly depending upon the: -Number and nature of the users of the application -Scope and duration of the application -Nature of the data involved -All of the choices are correct.

All of the choices are correct.

The systems implementation stage of application development involves: Hardware and software acquisition Conversion of data resources Testing of programs and procedures All of the choices are correct.

All of the choices are correct.

Which of the following statements about documentation is true? Documentation is no longer important because commercial software has online help systems, backed up with Internet-based help systems Documentation serves as a method of communication among the people who develop, implement, and maintain a system Only program modifications and/or customizations need to be documented Documentation is the most expensive part of any system implementation

Documentation serves as a method of communication among the people who develop, implement, and maintain a system

All of the following are done during the systems investigation stage of application development, except: -Each evaluation factor is assigned an equal weight -Each evaluation factor is assigned a different number of points, depending on its importance to the company -The lowest bid is always the ultimate selection factor -Only three things matter: cost, performance, and support

Each evaluation factor is assigned a different number of points, depending on its importance to the company

When a company needs to evaluate competing proposals for hardware or software acquisition: Network reliability

Each evaluation factor is assigned a different number of points, depending on its importance to the company
