         For example, SizeUK used eight centers, three scanners, and three sets of equipment
         plus one expert support team to complete data collection within a 6-month time and
         funding frame.


         3.4.3.3 Processing subjects
         Prior to the arrival of the subjects to be measured, the data collection team (with assis-
         tance from the support team) needs to

         l  set up and check the data collection center,
         l  calibrate and test all equipment,
         l  organize ancillary materials (such as scan wear/underwear),
         l  set up appropriate internal and external signage (e.g., guidance for those arriving, visuals of
            the scanning process, postures, health, and safety guidance and help in navigating within the
            center).
         On arrival at the center, subjects are welcomed, and the team confirms registration and
         ensures completion of a data protection document (e.g., confidentiality agreement)
         before explaining the measuring sequence and the required process needed for each
         individual item of equipment.
            All procedures for the maintenance of hygiene and safety need to be observed
         throughout preparation, before and after scanning and data collection.

         3.4.3.4 Data quality

         If the planning and preparation for a survey is carefully considered (e.g., a
         benchmarking exercise has been undertaken), then in-process validation of scans,
         landmarking, and measurements, whether manual or automatically extracted, should
         be easily assimilated into the subject processing sequence. However, the data quality
         maintenance procedures followed would depend on the selected measurement process
         and the type of scanners selected for use. For example, validation could include

         l  intra- and interevaluation of manually placed landmarking and measuring,
         l  checks to define or modify preset landmarks and measurements (Preiss and Botzenhardt,
            2012),
         l  the visual appraisal of all scans and automatically extracted measurements so that (where,
            e.g., a subject has moved or has assumed an incorrect posture) a repeat scan can be made.

         3.4.3.5 Data tracking

         At the end of the measuring process, a team member would need to verify completion
         using a subject barcode and, if necessary, complete the process with the issue of a for-
         mal thank you card, shopping voucher, or agreed industry partner gift (e.g., dressing
         gown). At the end of each session, the team would
         l  ensure that data have been successfully transferred to the logistics system,
         l  clean and close down all equipment in preparation for the next session,
         l  help the support team at the end of data collection exercise to derig the center and secure
            equipment and materials for transportation.
