PERT chart
A system's _____ includes ongoing system support and maintenance costs, as well as acquisition costs.
Total cost of ownership
A business profile is a specific set of transactions, events, and results that can be described and documented.
True
A potential disadvantage of rapid application development is its lack of emphasis on a company's strategic business needs.
True
A risk management plan should define project roles and responsibilities, risk management methods and procedures, categories of risk, and contingency plans.
True
A state transition diagram shows how an object changes from one state to another, depending on events that affect the object.
True
As a rule, data flow diagrams should only show a data store when two or more processes use that data store.
True
Groupware programs enable users to share data, collaborate on projects, and work in teams.
True
Identifying all project tasks and estimating the completion time and cost of each is referred to as project planning.
True
In situations in which the same data travels to two or more different locations, it is appropriate to use a diverging data flow.
True
Object-oriented methodology is popular because it provides an easy transition to O-O programming languages such as Java, Smalltalk, C++, Python, and Perl.
True
People working in teams can use collaboration software, such as Google Docs and Microsoft Web Apps, to access data and share files.
True
Project managers often use a weighted formula for estimating the duration of each task.
True
Slack time is the amount of time a task can be late without pushing back the completion date of an entire project.
True
The Unified Modeling Language uses object-oriented design concepts and provides various graphical tools, such as use case diagrams and sequence diagrams.
True
The objective of the systems analysis phase is to understand the proposed project, ensure that it will support business requirements, and build a solid foundation for system development.
True
The _____ is a widely used method of visualizing and documenting an information system.
UML
Modular design is based on combinations of three logical structures, which are called sequence, selection, and _____.
iteration
Processes contain the business _____ that transform data and produce the required results.
logic
Modeling involves graphical methods and _____ language that represent the system at various stages of development.
nontechnical
A(n) _____, also known as a data structure, is a meaningful combination of related data elements that is included in a data flow or retained in a data store.
record
Information about projected future volume for all outputs, inputs, and processes is required in order to evaluate _____.
scalability
Project _____ involves selecting and staffing a project team and assigning specific tasks to team member
scheduling
System implementation
-Construct new system -programs are written and tested -System is installed -produce a functioning and documented system
Systems design
-Create a physical model -Design user interface -Identify outputs, inputs, and processes -produce system design specification
System Support and Security
-Must be secure, reliable, maintainable, and scalable -Must be updated or replaced after several years
Systems planning
-Systems request -preliminary investigation -feasibility study
Structured Analysis
-Time tested easy and easy to understand -Uses SDLC -Predictive approach -Uses process models to describe the system graphically
System analysis
-build logical model -perform fact-finding techniques -build business models, data and process models, and object models -produce system requirements document
Structured Analysis (Phases)
-systems planning -systems analysis -systems design -systems implementation -systems security and support
