INPUT DESIGN ANDOUTPUT DESIGN INPUTDESIGNTheinput design is the link between the information system and the user. Itcomprises the developing specification and procedures for data preparation andthose steps are necessary to put transaction data in to a usable form forprocessing can be achieved by inspecting the computer to read data from awritten or printed document or it can occur by having people keying the datadirectly into the system. The design of input focuses on controlling the amountof input required, controlling the errors, avoiding delay, avoiding extra stepsand keeping the process simple. The input is designed in such a way so that itprovides security and ease of use with retaining the privacy.
Input Designconsidered the following things:Ø Whatdata should be given as input?Ø How the data should bearranged or coded?Ø The dialog to guide theoperating personnel in providing input.Ø Methodsfor preparing input validations and steps to follow when error occur. OBJECTIVES 1. Input Design isthe process of converting a user-oriented description of the input into acomputer-based system. This design is important to avoid errors in the datainput process and show the correct direction to the management for gettingcorrect information from the computerized system.
2. When the data isentered it will check for its validity. Thus the objective of input design isto create an input layout that is easy to follow OUTPUTDESIGNAquality output is one, which meets the requirements of the end user andpresents the information clearly.
In any system results of processing arecommunicated to the users and to other system through outputs. In output designit is determined how the information is to be displaced for immediate need andalso the hard copy output. It is the most important and direct sourceinformation to the user. Efficient and intelligent output design improves thesystem’s relationship to help user decision-making.Theoutput form of an information system should accomplish one or more of thefollowing objectives.
v Conveyinformation about past activities, current status or projections of thev Future.v Signalimportant events, opportunities, problems, or warnings.v Triggeran action.v Confirman action.
