A systems building approach in which the system is developed as successive versions, each version reflecting requirements more accurately, is described to be
iterative.
Changes in hardware, software, documentation, or production to a production system to correct errors, meet new requirements, or improve processing efficiencies are termed

During the ________ stage of system development, system specifications that were prepared during the design stage are translated into software code.
programming
You are an IT project manager for an advertising firm. The firm wishes to create an online 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 service. 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. What development method would be most successful for this project?
prototyping
Acceptance Testing
provides the final certification that the system is ready to be used in a production setting.
