I would follow ISO:9001, the standards that specify quality management. Quality is an important part of the entire project and these guidelines help make sure that industry standards are met while meeting the demands of the customer. These processes can help with organization and efficiency of the project as well as to detect possible areas of improvement in company procedures.ISO:9001 outlines the required documentation, planning, responsibilities of management, steps from design to delivery, and improvement procedures such as internal audits and corrective and preventive actions. Currently if a company is ISO:9001 certified it gives them more credibility.
