Chapter 12 Answ

Chapter 12 (100/100) _____ requires unbiased and careful questioning of whether system elements are related in the most effective ways, considering new or different relationships among system elements, and possibly introducing new elements into the system. a G our Critical analysis Creative analysis Causal analysis Data flow analysis A scrum team usually consists of _________. eschoci w anserofG oupr twelve to fifteen people fifteen to twenty people more than twenty people less than a dozen people The Pareto principle is also known as the _____. eschoci w anserofG oupr 80-20 rule result rule cause rule 50-50 rule In the context of data-flow diagrams (DFDs), a(n) _____ shows either the source or destination of the data. eschoci w anserofG oupr data-flow line entity symbol data store symbol process symbol Tara and Zach are leading a systems development project and they want the investigation phase to go smoothly and quickly. They decide to use _____ because it will also help with the analysis and design phases. eschoci w anserofG oupr agile systems development functional decomposition joint application development direct observation Laura is carefully estimating the time required for each phase of a proposed system development project to see if her company can meet the client's desired time for completion. Laura is checking on ___________. eschoci w anserofG oupr schedule feasibility economic feasibility deadline feasibility technical feasibility _____ determines whether the expected benefits associated with a project outweigh the expected costs sufficiently to make the project financially attractive. eschoci w anserofG oupr Economic feasibility Technical feasibility Legal feasibility Operational feasibility A _____ is a description of the logical and physical structure of data and the relationships among the data for each user. eschoci w anserofG oupr schema cold site process data dictionary _____ creates a complete set of technical specifications that can be used to construct an information system. eschoci w anserofG oupr Systems design Systems analysis Systems investigation Systems development In the context of data-flow diagrams (DFDs), the _____ includes arrows that show the direction of data movement. eschoci w anserofG oupr entity symbol process symbol data-flow line data store symbol Once new software has been selected, implementation will include all of these tasks EXCEPT _________. eschoci w anserofG oupr consulting with stakeholders to establish future needs training end users customizing any aspects of the solution needed configuring all of the software's capabilities and options to meet requirements _____ involves testing the complete, integrated system (hardware, software, databases, people, and procedures) to validate that an information system meets all specified requirements. eschoci w anserofG oupr Integration testing User acceptance testing Volume testing System testing The goals of _____ are to determine the work load at which systems performance begins to degrade and to identify and eliminate any issues that prevent the system from reaching its required system-level performance. eschoci w anserofG oupr volume testing user acceptance testing unit testing integration testing _____ explains the purpose of every major piece of computer code and also identifies and describes key variables. eschoci w anserofG oupr Systems documentation Agile documentation User documentation Technical documentation Your new software project manager is OK with requirements that are not fully specified up front. He recommends a team-based approach to development. He is very likely to be a proponent of the _______ approach to software development. eschoci w anserofG oupr packages solution outsourced Waterfall Agile The process of switching from an old information system to a replacement system is called _____. eschoci w anserofG oupr cutover site preparation conversion installation You are part of the team to implement new software at XYZ Inc. The employees at XYZ Inc. trust the results of the old software programs, but are cautious about accepting the outcomes of the proposed new software programs. What software implementation strategy would you recommend in this situation? eschoci w anserofG oupr Parallel start up Pilot startup Direct cutover Phase-in approach You are part of a testing team at a software business. Your job is to see how many concurrent users the system can host and how many database transactions the system can handle without a noticeable drop in performance. You are doing _____ testing. eschoci w anserofG oupr system testing acceptance testing volume testing integration testing Which of the following statements is true of user acceptance testing (UAT)? eschoci w anserofG oupr UAT involves linking individual components together and testing them as a group to uncover any defects in the interface. A goal of UAT is to determine the work load at which systems performance begins to degrade. UAT must be completed successfully before newly developed software can be rolled out to the market. UAT is often done by independent testers who were not involved in developing program code. _____ involves running a complete new system for one group of users rather than all users. eschoci w anserofG oupr Phase-in approach Pilot start-up Cutover Parallel start-up _____ involves using a new or modified system under all kinds of operating conditions. eschoci w anserofG oupr Systems operation System construction Systems modification Systems review _____ is an iterative system development process that develops a system in "sprint" increments lasting from two weeks to two months. eschoci w anserofG oupr Individual development Object-oriented development Agile development Prototyping After the software is implemented, some modification is done on the software during maintenance. Suppose the customer data analysis software used by ABC Bank was significantly changed, but no new features were added. This type of maintenance is called a _______. eschoci w anserofG oupr version patch slipstream upgrade release A new _____ is a major program change, typically encompassing many new features. eschoci w anserofG oupr slipstream upgrade patch release version _____ is the process of analyzing systems to make sure they are operating as intended. eschoci w anserofG oupr System maintenance System construction System operation System review
