Ah! I get it now! Private sector acquisition and public sector acquisition have two very distinct "flavors." in public sector, tangible acquisitions are one piece of the puzzle, but it includes heavy contract-based work, as well as 8 million other facets. So if I'm modernizing, say, AVS' load balancing system (simple example), I'll need to get F5 into the picture, I'll need to jump through eight hoops to get the funding, and will draft a schedule that plugs into a program IMS, and so and and so forth (ZZZzzzZZZzzz)...but the crux of this effort will be contracting a firm to manage the installation and testing of the load balancers.
Now...if this were private sector, I could allocate the funds for the F5 installation, but get my buddies Dave and Alex from college to come on a weekend (they become "D&A Systems" for the weekend) and install the load balancers for $2000, and then brag to the CEO of how I just saved the company $X0,000 dollars by leveraging my professional network. Lol.....I started in the private sector; it can be a different world.
