The right document control system will help you to improve efficiency across your entire operations otherwise inefficiencies can cause unnecessary and potentially costly delays, and possibly lead to compliance issues. There should be a defined document hierarchy clearly describing the function and information of each controlled document .The professional technical writers can improve the quality of documents it can be done by establishing standardized training to technical writers. If a document is not easy to access precisely when it is needed, it is useless. Making documents easily accessible throughout the document lifecycle is another important document control tenet. A document’s current revision status must always be identified with electronic systems, the most current document version is provided automatically , with paper-based systemshuman error can often lead to mistakes in tracking and identifying the most current revision number. Companies should routinely review their documents for continued validity and determine whether the information contained in the document is still accurate and relevant. Depending upon the findings, the document will either be re-approved as is, updated as necessary, or retired.
