A data flow consisting of several sub-flows on a level-n diagram can be split apart on a level-0 diagram for a process that accepts this composite data flow as input.
F
A data flow diagram (DFD) is a picture of the movement of data between external entities and the processes and data stores within or outside a system.
F
A data flow has multiple directions of flow between symbols. It may flow in both directions between a process and a data store to show a read before an update.
F
A data store is data at rest and may represent only one physical location for data.
F

Component based development is the opposite of object-oriented development.
F
Creative design and development is a part of the marketing Web-based system costs.
F
DFDs do a very good job of representing time. On a given DFD, there is an indication of whether a data flow occurs constantly in real time, once per week, or once per year. There is also an indication of when a system would run.
F
DFDs do not provide notation but illustrate important concepts about the movement of data between manual and automated steps.
F
Data flow diagrams are non-versatile diagramming tools and consist of only three symbols.
F
Detailed task and activities estimates are completed during the project initiation and planning phase.
F
Every project uses all of the project initiation activities.
F
If a company chooses to not to outsource their information technology, their only other option is to build the systems in-house.
F
In information systems planning, technology blueprints would be found in the current situation step.
F
Interpreting system requests and specifications is not a skill required as part of the customer relations activity for a project manager.
F
Intuit is an example of an IT services firm.
F
Key business processes are management focused.
F
Managed reuse is a less expensive method of managing software reuse.
F
Managers should consider disruptive technologies when applying inductive thinking.
F
Open ended questions have a pre-specified answer.
F
Oracle is a software company known for productivity software.
F
The Project Workbook is an offline or hard-copy repository for all project correspondence, inputs, outputs, deliverables, procedures, and standards that is used for performing project audits, orienting new team members, communicating with management and customers, identifying future projects, and performing post-project reviews.
F
The baseline business plan is a type of project and contains steps for overall systems development.
F
The most used approach to describing the current situation is a top-up approach.
F
The second phase in the SDLC is Design.
F
Users, management, and customers verify the BPP.
F
When a steering committee chooses a project it is referred as a bottom-up source.
F
When an organization outsources to a company, the company fires the employees of the original organization.
F
A project with high risk may not be conducted.
False
A study that determines if the proposed information system makes sense for the organization from an economic and operational standpoint is called non-feasibility study.
False
An example of a requirement for project selection is ease of training.
False
Objective statements is the method of an organization fulfilling its mission and objectives.
False
Operational feasibility deals with project duration.
False
Rejection of a project is the only outcome in the classifying and ranking of projects.
False
The baseline business plan is a type of project and contains steps for overall systems development.
False
The last deliverable, or end product, produced by Chris and Juanita was a System Service Request (SSR), a standard form PVF uses for requesting systems development work.
False
The primary deliverable form the planning phase of IS development projects is incremental commitment.
False
The second step in selection of a project is reviewing the current projects and removing the ones that do not line up with strategic goals.
False
Top management most often chooses project with a narrow tactical focus.
False
Using a weighted system, requirements and restraints should be given equal weights.
False
When a steering committee chooses a project it is referred as a bottom-up source.
False
A development group selection method looks for projects with fewer development delays.
T
A level-0 diagram represents the primary individual processes in the system at the highest possible level.
T
A level-1 diagram is a DFD that represents a system's major processes, data flows, and data stores at a high level of detail.
T
As analyst you want to pick normal and abnormal conditions when observing employees.
T
Building an economic case for a project is an open ended activity.
T
Designed reuse is the most expensive approach to reuse.
T
Development of an executive support system is an example of risky project.
T
During schedule feasibility it is a good practice to not have system testing during holiday periods.
T
Executing the project is the third phase in the project management process.
T
Once the DFDs are complete, we can examine the details of individual DFDs for such problems as redundant data flows, data that are captured but are not used by the system, and data that are updated identically in more than one location.
T
When you decompose a DFD from one level to the next, there is a conservation principle at work and we must conserve inputs and outputs to a process at the next level of decomposition.
T
With throwaway prototyping there is never an intention to create a working system.
T
The scope of information systems is concerned with the entire company.
True
Continual user involvement works best with a large development team.
f

f
JADs are best held at the corporate office where everyone's office is nearby.
f
One of the key emphases of eXtreme Programming is to use a three-person programming team.
f
