System Development, Performance Improvement, Systems Analysis, User Relations, Project Management Software, Project Life Cycle, Prototype, and System Design
Prototyping of a computer system has not typically been a course taken by many systems analysts. The advantages and disadvantages indicate that a more efficient system with a better fit results when prototyping is used. Typically problems emerge as system development progresses. Prototyping allows for early analysis of the problems and facilitates the integration of their solutions into the final system. The mutual learning of user and analyst while prototyping diminishes communication problems.
Data Processing, Software Selection, Productivity, Integrated Software, Functional Capabilities, and User Interface
A data processing department should select software that is designed for its particular needs. The selection of software can determine the productivity of the department. An integrated software system should be selected that provides the following: easy-to-use applications for different levels of users, components that work well together, adaptability to both simple and complex situations. The software should provide for user-system interface through features such as menus that guide a user through the necessary operating steps, prototyping that allows a user to test the program, and step level refinement that enables simple corrections or changes. The correct software can result in increased productivity without the addition of staff or hardware.

User Relations, System Development, User Need, Prototype, Systems, and System Design
According to Merle Parks, product manager for Cincom, DP personnel need to recognize the following myths when developing applications: users' needs are static, users know what they want and users can communicate their needs to DP. When dealing with users, the system developer should illustrate several types of systems via menus. A photograph of Merle Parks is included.
Not many people build their own home computers from scratch anymore. However, one way to enchance any computer is to add on peripheral devices. To do this, one needs to understand how to put information in and get information out of the computer. In other words, one needs to understand an I-O prototype system. The included tables explain I-O theory. The included schematic diagrams show proper line connections. The listed programs allow for testing several I-O functions.
