After the requiring activity has written their SOW/PWS, figured out source selection approach, then selected factors and subfactors, then figured out weighting of non cost/price factors, then understood consequences of the above, they write a source selection plan (SSP). A SSP gives instructions to a source selection committee on how to evaluate each proposal. Courts will defer to the source selection committee's business judgment, so facts must be included to base a decision on; the source selection committee must not be arbitrary or lack facts in the record for their findings.
