n your post, consider the various attributes of a transportation management system (TMS), rate shopping, routing optimization, shipment tracking, payments and invoicing, and reporting. Explain which capability you feel is the most important aspect when developing a transportation network and choosing a TMS. Does this perspective change as you move up the pyramid of transportation management as discussed in Module Four? In response to your peers, comment on the decision of your peers as to which TMS capability is the most important. How would their decision impact the level of service and cost elements of a transportation channel? You should also include relevant research and sources related to this topic. Be sure to use proper citation and formatting
