What is input design and output design in system design?

Answer 1

Input design

Input facilities the entry of data into the computer system. Input design involves the selection of the best strategy for getting data into the computer system at the right time and as accurately as possible. This is because the most difficult aspect of input design in accuracy .The use of well-defined documents can encourage users to record data accurately without omission.

For example, if a customer's telephone number is a needed input data, the slaes order form should have a specific line that is clearly labeled "customer telephone number". Having several lines labeled "customer information" would be less effective. This is because sometimes only the name and address would be filled in leaving out the telephone number.

Input design must capture all the data that the system needs, without introducing any errors. Input errors can be greatly reduced when inputting directly by using appropriate forms for data capture and well designed computer screen layout.

Answer 2

Design input may take many different forms, ranging from a vague concept in someone's head, roughly sketched on a cocktail napkin to detailed specifications/requirements. In general, a thing that is the subject of design activities is expected to do something, and often what it's expected to do is described in terms of limits or ranges. A building must have x square feet of floor space, have a brick exterior and conform to local building codes, e.g.. Whatever the thing is supposed to do forms the basis of design input.

Answer 3

Input design is an important aspect of system analysis and design that focuses on designing the methods and procedures for collecting and entering data into a computer-based information system.

Effective input design involves understanding the needs of the users and the requirements of the system, and creating an interface that is easy to use and minimizes errors. This includes defining the data to be collected, determining the appropriate methods for data entry, and specifying the formats for data storage and retrieval.

Some of the key considerations in input design include:

Accuracy: The input design should minimize errors in data entry by providing clear instructions and validation checks to ensure that the data is entered correctly.

Completeness: The input design should ensure that all required data is collected and entered into the system.

Consistency: The input design should ensure that data is entered consistently across the system, using standardized formats and terminology.

Timeliness: The input design should ensure that data is entered in a timely manner, so that it is available when it is needed.

Overall, input design is critical to the success of a computer-based information system, as it ensures that the system collects and stores accurate, complete, and consistent data.
