Research concluded that using SCM tactics to standardize products will have benefits for all stakeholders on the project. In Case Study 7, standardization led to reduced lead-times as illustrated in Figures 9.19 and 9.20, shown below. In Case Study 1, standardization led to reduction of inventory and shortened the procurement cycle time. In Case Study 8, Butler Manufacturing Company used SCM tactics to standardize its product offerings, which led to less customized products and more efficiency. Ultimately, standard materials allows for greater manufacturing efficiency by the seller, less design review and approval cycles by the EPC, and ultimately better price, schedule, and quality for the end user. The pitfall is sub-optimization, which is where design changes required by the project outweigh any savings at the equipment level. (RR172-11, p. 123)
