Cost, schedule and performance risk can be increased by over-bundling of a requirement into a single acquisition exercise. Over-bundling dries up the possible vendor base that might otherwise compete for a requirement. Thus, it is critical that an evaluation of the potential vendors who might compete for the overall work statement / deliverables be accomplished. This analysis will frequently require splitting up a requirement into different components. The bundling of a requirement also has a detrimental effect on the SSCs and CLIN structure, making it difficult to use in source selection, price evaluation and contract administration. Northern Missouri congressman Sam Graves introduced draft legislation in 2014 intended to address some of the shortcomings of excessively bundled contracts.
