Output design

Output Design
1. Designing layout:
The arrangement of information on a monitor screen or printed on a paper is termed as layout. The output design is specified on layout forms, sheets that describe the location such as length and type of text, format of column headings, pagination, etc.

2. Category of output:
                                          i.            External
                                       ii.            Internal

3. Report generation:
Printed reports are formal documents that provide users with the information so that users can perform their jobs effectively. It must be clear and easy to understand. We have to consider some features while designing a report such as : titles, subtitles, date, page no and summary.
4. Design of screens:
The reports which are to be shown on a computer screen must be given a clear instruction how a user proceed to retrieve the information. It also include some facility such as user friendly message or pop ups for helping the users.

5. User interface design:
A User Interface is a combination of menus, screen design, keyboard commands and language which together create the way a user interacts with the system. It determines how user interacts with system. The hardware part of user interface consists of monitor, keyboard and mouse. The software part of interface determines what things look like on the screen and how user gives commands to get work done.

Features of good user interface:
                                                                  i.            Know the prospective users of the system and their requirements.
                                                               ii.            The interface should be robust i.e. the interface should not be fail because of some erroneous actions taken by the user. It requires sufficient checks to prevent the users from taking some false actions.
                                                            iii.            If feasible, graphical icons must be used so that key-strokes can be minimised.
                                                             iv.            Test the user interface on actual users.
                                                                v.            Practice iterative (repeated) design.
