IS 5003 CHAPTER 12 – Flashcards

A native app is one that is designed to run on a specific platform.

Documentation reveals how well the system has met its original objectives.

A new information system is not considered in production until conversion is complete.

Gantt and PERT charts are two common formal planning tools for project management.

Prototyping is more iterative than the conventional lifecycle.

One problem with prototyping is that the systems constructed thereby may not be able to handle large quantities of data in a production environment.

End-user-developed systems can be completed more rapidly than those developed through the conventional programming tools.

Intangible benefits of an information system are those that cannot be easily quantified.

Object-oriented development is more iterative and incremental than traditional structured development.

You are an IT project manager for an advertising 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 service.
