One of the key elements of the 1930s concept of Group Technology OT is the classification of individual parts into families of parts with similar attributes. Prior to the advent of zone construction in ship- building similar products, such as franes, floors and shell plates, were presented on separate drawings, which resulted in the grouping of similar materials on each drawing. The assembly process followed a similar logical pattern using each of the drawings in each stage of construction. The introduction of zone construction has applied these OT concepts to the unit assembly process. Computer Aided Process Planning CAPP and its requirement to organize manufacturing data in a logical, structured manner has brought the shipbuilding industry back to the GT concept in the structural fabrication shop . The subdivision of a ship into manageable subsets of interim products allows for the further grouping of interim products into families requiring similar manufacturing processes.
