The
design of input focuses on controlling the amount of input required,
controlling the errors, avoiding delay, avoiding extra steps and keeping the
process simple. The input is designed in such a way so that it provides
security and ease of use with retaining the privacy. Input Design considered
the following things:

Ø What
data should be given as input?

Ø  How the data should be
arranged or coded?

Ø  The dialog to guide the
operating personnel in providing input.

Ø Methods
for preparing input validations and steps to follow when error occur.

 

OBJECTIVES

 

1. Input Design is
the process of converting a user-oriented description of the input into a
computer-based system. This design is important to avoid errors in the data
input process and show the correct direction to the management for getting
correct information from the computerized system.

2. When the data is
entered it will check for its validity. Thus the objective of input design is
to create an input layout that is easy to follow

 

OUTPUT
DESIGN

A
quality output is one, which meets the requirements of the end user and
presents the information clearly. In any system results of processing are
communicated to the users and to other system through outputs. In output design
it is determined how the information is to be displaced for immediate need and
also the hard copy output. It is the most important and direct source
information to the user. Efficient and intelligent output design improves the
system’s relationship to help user decision-making.
