It is common for contractors to provide capability briefings to government agencies who may at some point require the type of services these contractors can provide. This is a good business practice and it is beneficial to both parties, to the contractor, but especially to the government.
For the government, capability briefings are part its market research. Good market research leads to a good acquisition plan. A good acquisition plan leads to a precise work statement (the guts of an RFP). And a precise work statement makes it a lot easier to keep the contractor on track during the period of performance. Not only that, but a clear, concise performance work statement resulting from thorough market research and acquisition planning tends to ensure that the government actually gets what it's contracting for. That doctrine holds true whether contracting for product development or for services.
Especially for services.
