What is the correct order of implementing list items during initial implementation?

We are implementing NetSuite for the first time. Unfortunately, our Inventory Items and Assemblies were loaded before a proper decision was made to adopt Standard Costing method and a robust chart of accounts developed to support Standards and variances. We also plan to value our raw materials at Landed Cost. The Landed cost templates had not yet been developed and there is still the standard cost model to introduce to the system.

Given the above, it seems that the implementation consultants should have a robust model to follow to advise and direct their new customers on the proper decision making sequence before entering all the configurations necessary for a successful implementation.
