PfSA personnel are experienced in proposal writing for large DoD and DoE programs as well as smaller IR&D and SBIR projects. The founders and staff have extensive technical and line management experience, which ensures an understanding of the importance of adhering to schedule and cost requirements. All projects and work packages are tracked in-house using MS Project™ software in addition to any project schedules used by the customer. PfSA handles all administrative tasks and issues associated with projects including security clearances, patents and confidentiality agreements, accounting and cost estimates, and the development and maintenance of detailed project schedules.

Upon discussion and clarification of customer requirements, PfSA personnel will write a proposal for the job which includes a statement of work, project deliverables, list of tasks and task descriptions, hardware and software requirements, preliminary cost estimate, and preliminary project schedule. Experimental work may be conducted in PfSA facilities or at the customer's facilities. Typically, software development and design work is conducted at PfSA, although special requirements may dictate other arrangements.

Progress reports, including updated schedules for each task, will be provided monthly or at intervals consistent with customer requirements. Vugraph presentations will be prepared by PfSA staff, typically in MS Power Point™, and previewed by the customer. Presentations will be given by PfSA staff, via teleconferencing or in person, or by customer staff as required.
