Rad makes extensive use of _______________process to gather data and perform requirements analysis.
joint application development (JAD)
any sytems development project in which the primary effort is undertaken by a combination of business managers and users
end-user systems development

project schedule
The _________is used to support projects where the primary effort is undertaken by a combination of business managers and users.
end-user SDLC

End-user SDLC
What enables detailed development, tracking and control of the project schedule
the use of automated tools
a critical date for the completion of a major part of the project
project milestone

project deadline
all activities that, if delayed, would delay the entire project
critical path
With the _____________approach, a project can be broken down into a group of objects that interact.

upper-CASE tools
tools that focus on the later implementation stage of systems development and can automatically generate structured program code
lower-CASE tools
tools that link upper-and lower-CASE tools
integrated CASE tools I-CASE
approach that combines the logic of the systems development life cycle with the power of object-oriented modeling and programming
OOSD object-oriented systems development
