Market research is an iterative process for gathering
data on suppliers' capabilities, the characteristics of their products, and
their standard business practices. This research is necessary to obtain
information on candidate COTSNDI products that may meet the draft power supply
performance specification and support requirements (see Appendix A).
When performed early in the Concept Exploration phase, market research can
also help in decisions regarding the power system design and support concept
to be implemented.
market research data is analyzed to determine with confidence whether:
- the program's requirements can be met by available COTS/NDI power
- the suppliers are able to modify their COTS/NDI power
- a custom development effort must be conducted.
The potential suppliers are assessed through various
means, such as manufacturing surveys/ evaluations (see Appendix C, Modified
COTSNDI and Custom Power Supply Supplier Evaluation), past performance, design
and test data, cost information. Should the information to conduct such
assessments not be available or inadequate to determine whether or not the
COTSNDI products can meet the expected weapon system application and
environmental requirements, additional analyses and testing may be
required. The market research data and trade study findings (see Subsection 1.5,
) may result in modification of the power
supply performance specification and related support requirements.
cost and schedule to modify a COTSNDI power supply or develop a Custom power
supply can vary significantly depending on the specific application
requirements. The following three subsections provide insight, for
comparison purposes, that may aid program managers in making the right decision
regarding the category of power supply selected.
1.4.1 Power Supply
Power supplies for the military environment which fall
into any one of the three power supply categories can also have a wide
spectrum of configurations. The associated design and manufacturing
effort can vary from simple to complex, with cost affected accordingly.
For purpose of comparison, a rough estimate of the acquisition and development
time for each power supply category is shown in Table 1.4- 1.
1.4.2 Power Supply Selection / Development Man-Hours
Custom Power Supply Development
Cost as a Percent of Weapon System Cost System contractors who both
manufacture and purchase power supplies estimate the power supply development
cost at 5% to 10% of the total weapon system development cost, excluding
software. The development cost is estimated based on anticipated
man-hours plus material, which often includes subcontracted environmental and
electromagnetic interference/ compatibility (EMI/EMC) testing. The
development cost must be modified upward for a stateof-the art design.
Recurring power supply cost may be estimated as 2.5 to 5 times the Bill of
Material plus additional costs imposed as a result of production environmental
stress screening (ESS). This ESS typically amounts to 5% to 10% of the
total recurring power supply production cost.
