Input design and output design

INPUT DESIGN
The input design is the link between the information system and the user. It
comprises the developing specification and procedures for data preparation
and those steps are necessary to put transaction data in to a usable form for
processing can be achieved by inspecting the computer to read data from a
written or printed document or it can occur by having people keying the data
directly into the system. 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:
 What data should be given as input?
 How the data should be arranged or coded?
 The dialog to guide the operating personnel in providing input.
 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 correctinformation from the computerized system.

2. It is achieved by creating user-friendly screens for the data entry to handle
large volume of data. The goal of designing input is to make data entry
easier and to be free from errors. The data entry screen is designed in such a
way that all the data manipulates can be performed. It also provides record
viewing facilities.
3.When the data is entered it will check for its validity. Data can be entered
with the help of screens. Appropriate messages are provided as when needed
so that the user
will not be in maize of instant. 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.
1. Designing computer output should proceed in an organized, well thought
out manner; the right output must be developed while ensuring that each
output element is designed so that people will find the system can use easily

and effectively. When analysis design computer output, they should Identify
the specific output that is needed to meet the requirements.
2.Select methods for presenting information.
3.Create document, report, or other formats that contain information
produced by the system.
The output form of an information system should accomplish one or more of
the following objectives.
 Convey information about past activities, current status or projections
of the
 Future.
 Signal important events, opportunities, problems, or warnings.
 Trigger an action.
 Confirm an action.
