Data Maintenance and Quality Assurance

Data maintenance, quality control, and quality assurance are critical not only at this last step but continuously throughout your workflow. Maintaining your data makes production and dissemination more efficient. Quality control is paramount to avoid degrading data as edits are performed. Quality assurance is the verification and recording of data integrity before products are disseminated.
