you are an IT project manager for an advertisement firm. The firm wishes to create an online survey tool that will be used to survey focus group reactions to products in development. The most important consideration for the firm is being able to offer the tool as soon as possible as a new corporate services. However, you know that many of the senior managers that are business owners of this project have difficulty in understanding technical or software development issues, and are likely to change their requirements during the course of development.

data flow diagram
a________ shows each task as a horizontal bar whose length is proportional to the time required to complete it.
a business document indicating the direction of systems development, the ratioale, the current systems, new developments to consider, the managment strategy, the implementation plan, and the budget is called a
information systems plan
if an organizations requirements conflict with the software package chosen and the package cannot be customized, the organization will have to:
change its procedures
provides the final certification that the system is ready to be used in a production setting
object-orientated devlopment could potentially reduce the time and cost of writing software because
objects are reusable
an entire information system is broken down into its main subsystems by using:
high-level data flow diagrams
changes in hardware, software, documentation, or production to a production sustem to correct errors, meet new requirements, or improve processing efficiencies are termed:

the term structured, when discussing methodologies, refers to the fact that:
techniques are step by step, with each step building on the previous one
groups of objects are assembled into software comonents for common functions, which can be combined into large-scale business applications, in which type of software development?
which of the following tools may help identify risk associated with employess acceptance of a new information system?
organizational impact analysis
compared to the use of proprietary components, web services promise to be less expensive and less difficult to implement because of:
the use of universal standards
_______ are untangible benefits of information systems
improved asset utilization, increased organizational learning, and improved operations
the project risk will rise if the project team and the IS staff lack:
the required technical expertise
which process develops a detailed description of the functions that a new information system must perform?
______ provides software tools to automate development methodologies and reduce the amount of repetitive work in systems development
in an object-orientated development framework for a university, how would the classes Degree, mathematics, and physics be related?
Degree is a superclass to mathematics and physics
Determining methods for feedback and error handling would be defined by which system design specification category?
as a technical project manager you have decided to propose implementing a prototyping methodology for a small web-based design project. What is the order of steps you will follow in this project?
identify user requirements, develop the prototype, use the prototype, revise and enhance the prototype
what was the primary problem facing the Girl Scouts regarding their supply chain problems?
ordering process was inefficient for a large volume of orders
