You begin the review stage by reviewing and revising your own draft. You must check your draft for completeness, accuracy, and consistency during this stage along with a check for the Grammar guidelines and usage principles. You must send your document for a peer review. When you peer review, you not only check the Grammar and style aspects, but judge the quality of the document by taking into consideration the information needs of the end user.
Editing and proofreading together form an integral part of the review process. Editing is a formal process defined with set goals to improve the overall quality of the document and ensure that the document is technically accurate.
