Because of lack of coordination, the likelihood for mismatches to occur is high. When spools in Staged Spool and work areas in Work Area Ready cannot be matched for installation, staging areas will fill up with spools of no immediate use, and work areas remain unfinished. The peak at 570 for Staged Spool in Figure 3 (Right, Upper-middle) confirms this to be the case (590 spools on site is the maximum, as there are 600 spools in total, 15 areas requiring 40 spools each, and the next-to-last shipment of 10 should at the very latest complete five required sets of 40 spools).
