This document discusses input/output design and form design. It covers the objectives of input design which are to design data entry procedures, reduce input volume, design source documents and input records. Input media and devices discussed include keyboards, punch cards, OCR, barcodes and digital pens. Objectives of output design are to serve the intended purpose, meet end user needs, deliver appropriate quantity, format outputs correctly and make outputs available on time. Output media devices covered are CRT screens, printers, plotters, audio response and storage. Form design classification and types of forms are also mentioned. The prerequisites are understanding inputs and outputs needed for system development.

2. Input/Output & Form Design
Objectives
» What is input design and its objectives
» The various data capture media and devices.
» What is output design and various output media devices
» Forms, its classification and types of forms..
Prerequisites
This chapter requires the student to know the inputs and the outputs required for the development of the system.

3. Introduction
In input design user originated inputs are converted to a
computer based format. It also includes
» Record Media
» How to enter into the system
» Speed of capture
Input Design

4. Information Systems
Input
(Data)
Process
Output
(Information)

5. Input Design
Data
» Ease of entering data
» Logical Data
» Error free

6. Input Design
Data
» Type of Data
» Allocated Space
» Sequence
» Format

7. Objectives for Input Design
» To design data entry and input procedures
» To reduce input volume
» To design source documents for data capture or devise other data capture
methods
» To design input data records, data entry screens, user interface screens, etc.
» To use validation checks and develop effective input controls.

8. Source Document (Data Source)
» Source data are captured initially on original paper or
a source document.
» Example: Bank Cheque, Admission Form,
Application Form
Input Design

9. Input Media & Devices
» Keyboard
» Punch Cards
» OCR, MICR or Barcode
» Digital Pens
» Stored Data

11. MICR Code
MICR (Magnetic Ink Character Recognition)
MICR Scanners

12. Properties of well designed Input
» It should serve specific purpose effectively such as storing, recording,
and retrieving the information.
» It ensures proper completion with accuracy.
» It should be easy to fill and straight forward.
» It should focus on user’s attention, consistency, and simplicity.

13. Introduction
In input design user originated inputs are converted to a
computer based format. It also includes
» What media is used to provide input
» How to enter into the system
» Speed of capture
Output Design

14. Objectives for Output Design
» To develop output design that serves the intended purpose and eliminates
the production of unwanted output.
» To develop the output design that meets the end users requirements.
» To deliver the appropriate quantity of output.
» To form the output in appropriate format and direct it to the right person..
» To make the output available on time for making good decisions.
