A disadvantage of prototyping is that it encourages a return to the "code, implement, and repair" life cycle that used to dominate information systems.

An advantage of prototyping is that creativity can increase because it allows for quicker user feedback, which can lead to better solutions.

Prototypes can be quickly developed using many of the 4GLs and ________________________ languages available today.

Prototyping helps keep the scope and complexity of the system project under control.

A(n) ______________________________ (advantage or disadvantage) of prototyping is that it can reduce creativity in designs. The very nature of any implementation - for instance, a prototype of a report - can prevent analysis, designers and end-users from looking for better solutions.

Synonyms for modern structured design are: top-down program design and structured programming.

In the procurement phase, the first task is to research technical alternatives. This identifies specifications that are important to the software and/or hardware that is to be selected. These requirements specify the functionality, features, and critical performance parameters.

Structured design seeks to factor a program into the top-down hierarchy of modules that have the following properties - (1) modules should be highly cohesive; and (2) modules should be loosely coupled.

With prototyping there is no need for the systems analysis phases.

A disadvantage of prototypes is that they often suffer from slower performance than their third generation counterparts.

A structure chart:

For interface or dialogue design, the designer must consider such factors as terminal familiarity, possible errors and misunderstandings that the end-user may have or may encounter; the need for additional instructions or help at certain points, and screen content and layout.

The _______________________________ is used to establish the physical processes and data stores across a network.

Structured design seeks to factor a program into the top-down hierarchy of modules that have the following properties:

Issues to be addressed during database design include: data structures and their impact on performance and flexibility; record size and storage volume requirements; internal controls to ensure proper security and disaster recovery techniques.

Each application should implement its own database, independent of the other applications used by a firm.

The prototyping approach is an iterative process involving a close working relationship between the designer and the users where a working, programmed model of the system is used to facilitate the specification of the design.

A(n) ________________________________ (advantage or disadvantage) of prototypes is that they are an active, not passive, model that end-users can see, touch, feel and experience.
