The larger or more complex the system or the more delicate its elements, the more critical the proper sequence becomes, as small changes can cause large impacts on project results.
The optimal sequence of assembly is built from the bottom up as components become subelements, elements, and subsystems, each of which must be checked prior to fitting into the next higher assembly. The sequence will encompass any effort needed to establish and equip the assembly facilities (e.g., raised floor, hoists, jigs, test equipment, I/O, and power connections). Once established, the sequence must be periodically reviewed to ensure that variations in production and delivery schedules have not had an adverse impact on the sequence or compromised the factors on which earlier decisions were made.
