Process specifications CASE tools automate: User interfaces The most common form of IT-enabled organizational change is business process redesign. False Compared to the use of proprietary components, web services promise to be less expensive and less difficult to implement because of: Their ability to enable communication among different systems using universal standards Responsive web design enables websites to change layouts according to the user's screen size. True A native mobile app is: A stand alone application that does. . . Which process develops a detailed description of the functions that a new information system is a good system to begin with: Requirements analysis Organizations will adjust to new information systems without any special efforts if the system is a good system to begin with. False In a parallel conversion strategy, the new system: And the old are run in parallel The three main platforms for mobile apps are iPhone/iPad, iOS, and Android. False ________ provide[s] a detailed statement of the information needs that a new system must satisfy; identifies who needs what information, and when, where, and how the information is needed. Information requirements Categories of tools for BPM include all of the following except: Tools to test the security of business processes Acceptance testing: Provides the final certification that the system is ready to be used in a production setting 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 reaction to products in development. Prototyping The system is not in production until conversion is complete. True The process of creating workable information systems in a very short period of time is called: RAD ________ development focuses on rapid delivery of working software by breaking a large project into a series of small sub-projects that are completed in short periods of time using iteration and continuous feedback. Agile Which of the following is not a tool provided by Business Process Management software: Capture and identify information system requirements for a new system Organizational software packages often include ________ features that allow the software to be modified to meet organizational requirements. Customization Prototyping is more iterative than the conventional lifecycle. True ________ is the process of changing from the old system to the new system. Conversion Systems design: Shows how the new system will fulfill the information requirements. To understand and define the contents of data flows and data store, system builders use: A data dictionary A systems building approach in which the system is developed as successive versions, each version reflecting requirements more accurately, is described to be: Iterative Which of the following is not a top priority in mobile application development: Designing for keyboard data entry Objects are grouped into hierarchies, and hierarchies into classes. False The entire system-building effort is driven by: User information requirements The oldest method for building information systems is: The systems development lifecycle Business processes are analyzed, simplified, and redesigned in: Business process redesign Changes in hardware, software, documentation, or production to a production system to correct errors, meet new requirements, or improve processing efficiencies are termed: Maintenance A software package evaluation process is often based on a series of questions sent to vendors, called a: Request for proposal The primary tool for representing a system's component processes and the flow of data between them is the: Data flow diagram System testing: Tests the functioning of the system as a whole in order to determine if discrete modules will function together as planned What is the purpose of response web design? It allows one website to serve different platforms, such as tablets, PCs, and mobile phones Compared to the use of proprietary components, web services promise to be less expensive and less difficult to implement because of: Their ability to enable communication among different systems using universal standards A _______ is the model or blueprint for an information system solution and consists of all the specifications that will deliver the functions identified during systems analysis. Systems design document In an object oriented development framework for a university, how would the classes degree, mathematics, and physics be related? Degree is a superclass to mathematics and physics A structure chart is a bottom-up chart, showing each level of design, its relationship to other levels, and its place in the overall design structure. False During the _______ stage of system development, system specifications that were prepared during the design stage are translated into software code. Programming In order, what are the first three steps in BPM? 1. Identify 2. Analyze 3. Design Which type of systems development is characterized by significantly speeding up the design phase and the generation of information requirements and involving users at an intense level: JAD The four kinds of structural organizational change enabled by IT, in order from least to most risky, are: Automation, Rationalization, Redesigning, and Paradigm shift What is the purpose of responsive web design? It allows one website to serve different platforms, such as tablets, PCs and mobile phones Unit testing: Tests each program separately The idea that the achievement of quality is an end in itself describes a main concept of: TQM The oldest method for building information systems is prototyping. False A bank has reworked its mortgage application process so that several steps are handled by computer software, and some steps are combined to reduce bottlenecks in processing. The goal is to gradually improve its efficiency over time. This is an example of: Rationalization of procedures In what stage of systems development are design specifications created? Systems design What is "responsive design" for mobile applications? A design that responds to the user's digital device and screen End-user-developed systems can be completed more rapidly than those developed through the conventional systems lifecycle.
