NORMAL CURVE OR NORMAL DISTRIBUTION-MAED
- 2. Input/output design Identification of the specific outputs required to meet the information requirements. Selection of methods required for presenting information. Designing of reports, formats or other documents that acts as carrier of information.
- 3. The most important source of information is the output, efficient, intelligible output design should improve the system‟s relationship with the user and help in decision making.
- 4. •INPUT DESIGN The data base is the data that must be obtained and stored for later retrieval for managerial decision making. The most common cause of error during the data processing is inaccurate input. The inaccurate input is entered by data entry operators but it can be controlled by input design.
- 5. Objectives of input design: •Avoiding errors in data •Avoiding delay •Avoiding duplication of data •Avoiding extra steps •Controlling the amount of input required • Keeping the process simple
- 6. Activities involved in input design: •Collection of data •Conversion of the input data to computer acceptable form Checking the conversion •Transmitting the data to computer Checking the input data •Correct the error if error occur
- 7. Input layout Headings and date of data entry. Data type and width of the column Initials of data entry operator
- 8. Objectives of output design:- Carry information about past activities, current affairs or projection of the future Mark important events Take an action Confirm an action
- 9. Types of output •Report •Document • Message
- 10. PRESENTATION OF OUTPUT •The presentation of an output represented either in tabular or graphical form or in both forms. A tabular format is preferred in the following conditions: •When the details dominate the content of the output •When the contents of the output are classified in groups •When the output design are to be compared.
- 11. •Graphical representation are used to improve the effectiveness of the output because some users prefer to view information in graphic form rather than in rows and columns of the tables. •The tabular and graphical formats may be combined together to enhance the presentation of the output.
- 12. OUTPUT DESIGN SPECIFICATIONS The specifications for the output design should be considered first while designing any output. The main points in the output design specifications are Page title, number and date ,Paper size,Headings and date,Data and details,Notes and comments
