How do I do a price analysis on unknown travel?

First and foremost, consult your company's policies and procedures.

Often times the USG uses a "plug" number for travel because the locations and number of trips are unknown at the time the RFP is issued.  If the event you do not have clear policies on this, SpendLogic has a couple of options to consider when using the tool:

OPTION 1 (Select a "Part" called "Travel"):

Rather than adding a travel line (brings up the travel module), use/add the "PN" named travel. This will have a blank description you fill in, for example, budget, plug, etc.  You would enter a Quantity of (1) for this "Part".

SpendLogic utilizes the parametric method for analyzing and adds information as needed so an auditor or internal compliance understands what is being done in this analysis. Parametric (Yard Stick) Price Analysis - Training Video

OPTION 2 (Exclude Travel "Plug" number from Analysis):

You may opt to exclude this "plug" number from your analysis of a proposal since there is the likelihood of a requirement for all travel to be approved by the Contracting Officer.  If you exclude the "plug" number, be sure to include a statement to that effect in the Procurement Details of your price analysis in order for auditors and compliance to understand. 

You can award a Travel SLIN to your subcontractor but it would be at $0.00.  When travel requests with proposals are submitted, one can perform an analysis of travel using the Travel Analysis module since you will have all the elements to conduct a thorough analysis to include, the number of travelers, dates of travel, and location of travel. Purchase Orders/Subcontracts are then modified to increase ceiling/funding for the specific travel.  How do I analyze travel costs?
