Building Information Systems and Managing Markets and Projects

QuestionAnswer
It provides the final certification that the system is ready to be used in a production setting. Acceptance Tesing
This approach is to further expedite software creation, groups of objects have been assembled into software components for common functions, and these components can combined to create large-scale business applications. Component-based Development
It is also called computer-aided systems engineering and provides software tools to automate the methodologies to reduce the amount of repetitive work in systems development. Computer-aided software Engineering(CASE)
It is the process of changing from the old system to the new system. Conversion
It allow a software package to be modified to meet an organization`s unique requirements without destroying the integrity of the packaged software. Customization
It is the primary tool for representing a system`s component processes and the flow of data between them. Data Flow Diagram (DFD)
The direct cutover strategy replaces the old system entirely with the new system on an appointed day, carrying the risk that there is no system to fall back on if problems arise. Direct Cutover Strategy
Detailed documentation showing how the system works from both a technical and end-user standpoint must be prepared. Documentation
It allows end users, with little or no formal assistance from technical specialists, to create simple information systems, reducing the time and steps required to produce a finished application. End-user Development
It refers to the interaction of people and machines in the work environment. Ergonomics
It is for determining whether each proposed solution is feasible, or achievable, from a financial, technical, and organizational standpoint. Feasibility Study
They are for documenting and monitoring projects plans. Formal Planning and Tools
It lists project activities and their corresponding start and completion dates. Gantt Chart
It refers to all the organizational activities working toward the adoption and management of an innovation, such as a new information system. Impletmentation
Anew system identify who needs what information, where, when and how. Information Requirements
It shows how specific information systems fit into a company`s overall business plan and business strategy. Information Systems Plan
They cannot be immediately quantified, such as more efficient customer service or enhanced decision making. Intangible Benefits
It is used to accelerate the generation of information requirements and to develop the initial systems design. Joint Application Design (JAD)
Changes in hardware, software, documentation, or procedures to a production system to correct errors, meet new requirements, or improve processing efficiency. Maintenance
It uses the object as the basic unit of systems analysis and design. Object-Oriented Development
In addition to procedural changes, transformation in job functions,organizational structure,power relationships, and behavior should be identified during systems analysis using an OIA. Organization Impact Analysis
In a parallel strategy, both the old system and its potential replacement are run together for a time until everyone is assured that the new one functions correctly. Parallel Strategy
It stands for Program Evaluation and Review Technique, and graphically depicts project tasks and their interrelationships. PERT Charts
It introduces the system in stages (such as first introducing the modules for ordering Girl Scout cookies and then introducing the modules or transmitting orders and instructions to the cookie factory and shipper). Phased Approach
It will help you evaluate alternative system projects once you have determined the overall direction of system development. Portfolio Analysis
They describe the transformation occurring within the lowest level of the data flow diagrams, showing the logic for each process. Process Specifiations
During this stage,users and technical specialists review the solution to determine how well it has met its original objectives and to decide whether any revisions or modifications are in order. Production
It is a planned series of related activities for achieving a specific business objective. Project
It refers to the application of knowledge,skills,tools, and techniques to achieve specific targets within specified budget and time constraints. Project Management
It consists of building an experimental system rapidly and inexpensively for end users to evaluate. Prototyping
It refers to the process of creating workable systems in a very short period of time. Rapid Application Development (RAD)
It is a detailed list of questions submitted to external vendors to see how well they meet the requirements for the proposed system. Request for Proposal (RFP)
It defines what work is or is not included in a project. Scope
It gives alternative systems a single score based on the extent to which they meet selected objectives. Scoring Model
It is a top-down chart, showing each level of design, its relationship to other levels, and its place in the overall design structure. Structure Chart
It refers to the fact that the techniques are step by step,with each step building on the previous one. Structured
The testing process requires detailed testing of individual computer programs and it tests the performance of the information system as a whole. System Testing
Identify the problem,gather information,devise alternative solutions and make a decision about the best solution. Systems Analysis
It shows how the chosen solution should be realized. Systems Design
It is the oldest method for building information systems and is a phased approach to building a system,dividing systems development into a series of formal stages. Systems Development Lifecycle (SDLC)
They can be quantified and assigned a monetary value. Tangible Benefits
It includes all of the preparations for the series of tests. Test Plan
The system is thoroughly tested to ensure it produces the right results. Testing
The testing process requires detailed testing of individual computer programs and it tests the performance of the information system as a whole. Unit Testing
The relationship between end users and information systems specialists has traditionally been a problem area for information systems implementation efforts because of differing backgrounds, interests, and priorities. User-designer Communications Gap
is an organizational strategy to create a culture and environment that further promote rapid and agile development practices. DevOps
is an internet enabled app with specific functionality for mobiledevices Mobile web app
is a version of a regular website that is scaled down in content and navigation for easy access and search on a small mobile screen mobile website
is a stand alone application designed to run on a specific platform and device native app
enables websites to change layouts automatically according to the visitor screen resolution, whether on a desktop, laptop, tablet, or smartphone responsive web design
