A systems building approach in which the system is developed as successive versions, each version reflecting requirements more accurately, is described to be: end-user oriented. object-oriented. prototyped. iterative. agile.

iterative

Changes in hardware, software, documentation, or production to a production system to correct errors, meet new requirements, or improve processing efficiencies are termed: production. acceptance. maintenance. post-implementation. implementation.

maintenance

Object-oriented development could potentially reduce the time and cost of writing software because: a single user interface object can be used for the entire application. it's not necessary to use a formal methodology to design a system. iterative prototyping is not required. object-oriented programming requires less training. objects are reusable.

objects are reusable

In object-oriented development: data and processes are separated. processing logic resides within objects. the class is used as the basic unit of systems analysis and design. a strict, step-by-step development process is essential. an object is a collection of data that is acted on by external processes.
