Information requirements

You are an IT project manager for an advertising firm. The firm wishes to create an online tool that will be used to survey focus group reactions to products in development. The most important consideration for the firm is being able to offer the tool as soon as possible as a new corporate service. However, you know that many of the senior managers that are business owners of this project have difficulty in understanding technical or software development issues, and are likely to change their requirements during the course of development. What development method would be most successful for this project? Prototyping Traditional JAD RAD End-user development

Prototyping

Which process develops a detailed description of the functions that a new information system must perform? Systems design Requirements analysis Feasibility study Test plan development Management plan

Requirements analysis

What is the primary driving factor for firms in selecting domestic outsourcing firms to build system solutions? To take advantage of technical skills the firm does not have To reduce the cost of hardware To save labor costs To avoid offshore outsourcing To avoid change management issues

To take advantage of technical skills the firm does not have

To understand and define the contents of data flows and data stores, system builders use: user documentation. process specifications diagrams. a data dictionary. data flow diagrams. systems analysis.

a data dictionary.

In the traditional systems life cycle, end users: have no input. are limited to providing information requirements and reviewing the technical staff's work. are important and ongoing members of the team from the original analysis phase through maintenance. control the development of the system. are important only in the testing phases.

are limited to providing information requirements and reviewing the technical staff's work.

BPM software provides tools that help business do all of the following except: create models of improved processes. identify and document processes requiring improvement. capture and identify information system requirements for a new system. capture and enforce business rules for performing processes. integrate existing systems to support new or redesigned processes.

capture and identify information system requirements for a new system.

true or false? A prototype is a working version of an information system that serves as a final model.

false

true or false? Organizations will adjust to new information systems without any special efforts if the system is a good system to begin with.

false

Which of the following statements about CASE is not true? To be used effectively, CASE tools require organizational discipline. CASE tools facilitate the creation of clear documentation. CASE provides hardware and software tools. CASE tools can improve communication between users and technical specialists. CASE tools support iterative design.

middle

In object-oriented development: the class is used as the basic unit of systems analysis and design. data and processes are separated. processing logic resides within objects. a strict, step-by-step development process is essential. an object is a collection of data that is acted on by external processes.

processing logic resides within objects.

To show each level of a system's design, its relationship to other levels, and its place in the overall design structure, structured methodologies use: Gantt and PERT charts. process specifications. data flow diagrams. user documentation. structure charts.

structure charts.

Possible functions of BPM tools include all of the following except: testing the security of business processes. automating business processes. designing new processes. integrating existing systems to support business processes' improvements. identifying and document business processes.

testing the security of business processes.

The oldest method for building information systems is: computer-aided software engineering. prototyping. the systems life cycle. component-based development. object-oriented development.

the systems life cycle.

Compared to the use of proprietary components, web services promise to be less expensive and less difficult to implement because of: their ability to integrate seamlessly with legacy systems. the ubiquity of the Internet. the ability to reuse web services components. their use of custom programming. their ability to enable communication among different systems using universal standards.

their ability to enable communication among different systems using universal standards.

true or false? A request for proposal (RFP) is a detailed list of questions submitted to software vendors.

true

true or false? A structure chart is a top-down chart, showing each level of design, its relationship to other levels, and its place in the overall design structure.

true

___ provide(s) a methodology and tools for dealing with the organization's ongoing need to revise and optimize its numerous business processes. CASE tools Business process redesign Business process management TQM Systems analysis and design

Business process management

Which of the following is more powerful than rationalization of procedures? Systems analysis and design automation TQM Six sigma Business process redesign

false

true or false? The systems life cycle methodology maintains a formal division of labor between end users and information systems specialists.

true

The primary tool for representing a system's component processes and the flow of data between them is the: data flow diagram. process specifications diagram. data dictionary. object-oriented chart. structure chart.

data flow diagram.

Object-oriented development could potentially reduce the time and cost of writing software because: object-oriented programming requires less training. objects are reusable. it's not necessary to use a formal methodology to design a system. a single user interface object can be used for the entire application. iterative prototyping is not required.

objects are reusable.

true or false? The most common form of IT-enabled organizational change is automation.
