The quality of output information depends on the quality of input data. In other words, the accuracy, completeness, and relevance of the information being inputted into a system will ultimately determine the quality of the information that is produced as output. The quality of input data can be affected by factors such as the skills and training of the personnel entering the data, the accuracy of the tools and instruments used to collect the data, and the consistency and completeness of the data being collected. Therefore, it is essential to ensure that the input data is of high quality to produce accurate and reliable output information.
