Firm-Fixed-Price Contracts
Application Brief
Introduction
In defense contracting, firm-fixed-price (FFP) contracts are becoming more common than cost-
plus contracts. This fundamental shift in the business model begs an essential question: How can
organizations evolve to compete successfully in an FFP world?
Compared to cost-plus, FFP transfers much of the risk from the government to the prime con-
tractor. To mitigate these risks, contractors may want to reassess their assumptions and look for
opportunities to streamline or redesign their processes.
The math is simple: profit equals price minus cost. When the price is fixed, greater attention must
be paid to any and all costs that whittle away at the resulting profit. It may come as a surprise,
but test equipment is often the third-most expensive capital investment across the life cycle of a
system. To reduce the cost of test, two high-leverage action steps are available: pursue greater
reuse of test assets across multiple products and product lines, and implement new strategies for
test-asset acquisition.
This note presents context for the shift to FFP, suggests a few important implications, and offers
recommendations for effective reuse and acquisition of
test assets.
Problem: Juggling risks and costs
As noted above, FFP burdens the contractor with a greater share of the risks. The nature of
this shift is shown in Table 1.

Cash flow As incurred Delivery

Burden of risk Greater on government Greater on contractor
When faced with an emerging set of risks, the natural response is to identify ways to mitigate
those risks. For prime contractors, existing product lifecycle (PLC) processes were created
in a world of cost-plus contracts. With new underlying assumptions, it can be worthwhile to
examine those processes and redesign them for risk reduction versus a fixed price.
One key success factor is to modify core activities such that they can dynamically change while
ensuring minimal fixed costs. For example, in the 1990s many commercial electronics compa-
nies began outsourcing the fabrication of printed-circuit boards (PCBs) to contract manufactur-
ers (CMs). As market demand changed, this gave companies greater flexibility in managing the
costs associated with labor and manufacturing assets.
Reality check #1: Operation and support dominate total
cost of ownership
As one data point, a 2003 report from the US Government Accountability Office (GAO)
broke down the total cost of designing, building and operating a ship over its lifetime. The
conclusion: nearly two-thirds of the total cost went to operation and support (Figure 1).
The report also suggested that a greater investment in development costs focused on improv-
ing operation and support requirements would yield significant reductions in overall cost. For
example, designing out common maintenance items served to reduce overall crew size and
thus reduce ongoing support needs. 1

Reality check #2: Costs are locked in early
Another GAO report from 2003 concluded that 80 to 90 percent of the operating and
support costs of a weapon system will be determined as soon as the requirements are
set. However, at that point only 10 percent of the lifecycle costs have been spent. By
the time the system is ready for production, more than 90 percent of the operating and
support costs have been determined--but only 28 percent of the lifecycle costs have been
incurred. The distribution of these costs is shown in Figure 2. 2

Solution: Reducing the costs associated with
test assets
After buildings and land, test assets are often the third-most expensive capital investment
across the PLC--development, production and support. When dealing with FFP contracts, this
has two important implications. First is the need to reduce operating expenses through greater
utilization and optimized support of test assets. The starting point is a common test strategy
that enables greater reuse of test hardware and software. Ultimately, this can help maximize
your organization's return on invested capital (ROIC).
The second implication is the need to reconsider the available set of acquisition strategies
for test assets. In the past, "buy" was the default--and perhaps only--strategy deemed
acceptable by many prime contractors. Today, with FFP contracts, renting and leasing are viable
alternatives that can help reduce risks.
Step 1: Enhancing reuse of test assets
Traditionally, the incentives associated with cost-plus contracts led most aero/defense com-
panies to use a product-centric approach to design and manufacturing. In this paradigm, each
customer is treated as an individual product line with a specific set of products. What's more,
each product--in design and production--has a unique test strategy that is developed and
implemented separately from any other product or product line. Consequently, different sets of
hardware and software are developed, no matter how similar these may be across the various
products.

Step 1: Enhancing reuse of test assets (continued)
In the commercial world, manufacturers tend to use a process-centric point of view that spans
multiple products and product lines. Each customer is still treated in a unique way; however,
products are grouped according to common functions, features, or both. With this approach,
synergies between hardware, software and test methods provide useful leverage across many
products and product lines, independent of the end customer. This is the starting point for
greater commonality, utilization and reuse, and the beginning of reductions in engineering effort
and equipment expenditures.
This approach is also the foundation of a strategy that can help you succeed with FFP con-
tracts. The biggest benefit: it minimizes the risk and effort associated with developing, launch-
ing and manufacturing any new or enhanced product. Three key ideas help make asset reuse
a reality: mixed-product manufacturing, common measurement blocks and a common-process
test strategy.
Making the big shift: Mixed-product manufacturing
This is an important step in the shift from product-centric to process-centric manufacturing.
One of the best-known examples of mixed-product manufacturing is the model used by Toyota.
A Toyota production facility can, for example, build sedans, minivans and sports cars on the
same assembly line with no interruption to the manufacturing flow. The net effect: rather than
operating three separate lines that are partially utilized, one line runs at 100-percent utilization.
Figure 3 illustrates the difference between a set of independent production lines and one line
capable of running multiple products. This same methodology can be used for any set of similar
products once you understand how common measurement blocks and test reuse relates to
those products.

lines, the "common process center" can significantly Multiple independent product lines One common process center

When making the shift to a common process center, the starting point is to identify the com-
mon measurements that are required across a range of similar products. One way to make
this visible is to create a matrix that includes all products and all measurements: common and
unique requirements will become readily apparent (Figure 4).

similar products will help you identify common and

In many cases, you may find that a majority of the tests are common--and this means you can
use a common set of hardware and develop a common set of software modules. This approach
dovetails quite nicely with mixed-product manufacturing.
Pursuing a common-process test strategy
Combining common measurement blocks with test reuse is the next step toward a test strategy
that spans program lifecycles. This strategy also leverages previous investments in capital
equipment and engineering resources.
As with the measurement-blocks approach, a matrix is a good way illustrate the common-
process concept. As shown in Table 2, different products and their associated tests can be
integrated into common measurement blocks. When several devices-under-test (DUTs) share

This is the foundation of test reuse, which includes measurement hardware and software.
Benefits include greater test-asset utilization, less reengineering for new or enhanced products,
and the potential to lower the per-unit cost-of-test for every product and program.

introduction and maturity, spending typically increases in large steps because, in most cases,
producing one or more units above existing test capacity requires a complete new test stand.
After maturity, production volume goes into a decline, which means fewer test stands are
needed and the excess assets become a drain on ROIC.

Figure 6 shows a financially attractive alternative. When test demand reaches a predetermined
level, a leasing strategy is employed. This is not an arbitrary point. Rather, by understanding the
different breakeven costs for renting, leasing and buying, the length of time under the curve can
determine the best acquisition strategy.

In this case, the trigger point for the leasing of test assets occurs when the need is expected to
exist for more than one year and less than three years. Under these conditions, leasing is most
likely to minimize cost and risk, and thereby minimize the value of excess assets that remain
during the decline phase.

Reframing: Combining the strategies
Figure 7 shows the next logical extension of this strategy. When the concepts of common
hardware and software blocks are combined with flexible acquisition strategies, the result is an
overall test strategy that can be optimized for reuse, utilization and flexibility. As suggested in
the figure, test assets can be continually rolled forward and reused with new products that have
similar features, functionality and test needs. As in Figure 6, demand peaks can still be handled
through renting or leasing.

The interplay of these concepts is summarized in Table 3. Although none of the proposed
approaches is "one size fits all," matching each stage of the PLC with a favorable acquisition
strategy can help you reduce the total cost of ownership for your test assets.

can be a useful alternative that aerospace and defense contractors will want to consider.

Conclusion
Testing is still the best way to reduce the likelihood of a product falling short of its specifica-
tions. To ensure customer satisfaction and success, many organizations spend money on test
throughout the product lifecycle--but this form of risk mitigation can be expensive.
As shown here, you can reduce the costs associated with test assets by adopting or adapting
proven strategies from the commercial world. One common thread is the power of reusing
knowledge gained from previous products and programs. This is true in the use of common
measurement blocks and in the reuse of test assets. It is also true in the analysis of test-asset
acquisition strategies versus the usual progression of production volumes and test needs.
The ultimate benefit is clear: the decision to leverage knowledge gained in commercial manu-
facturing can help aerospace and defense contractors compete more successfully in a world of
FFP contracts. It will also position your organization to more easily adjust and adapt with future
changes in the business model.
