4.2.2 Environmental
engineering tailoring
tasks.
4.2.2.1 General.
b. As indicated in paragraph 4.1
above, the primary
benefits of performing these tasks come from the technical information and
structure they provide for the MNS,
ORD,
SAMP,
and TEMP.
This information covers natural and induced
environmental conditions. The structure provides an orderly means of uncovering
potentially significant environmentally-related failures during the acquisition
cycle rather than after fielding (storage,
transit,
operational modes). The environmental engineering tasks, then, help reduce
total ownership costs
in terms of decreasing early system failures, reducing system downtime, saving
repair/parts/logistic expenses, and even saving lives. 4.2.2.2 Preparing
an Environmental
Engineering Management Plan (EEMP), Task 401.
The EEMP is the basic management schedule used to integrate environmental
effects considerations into the SAMP.
This integration helps to ensure materiel will be prepared for all environmental
conditions to which it will be subjected during its life cycle. The EEMP identifies
manpower, dollar estimates, timing and points of contact necessary to complete
the remaining tasks (402 through 406). As indicated on figure
1-1, paragraph 4.1.2
and Appendix B, paragraph F, there may be times
that the program manager
has valid alternatives, such as modeling and simulation
or other analytic techniques, to testing actual materiel or working prototypes.
These alternatives are scheduled and justified in the EEMP. The EEMP is described
in Part One, Appendix A, Task 401.
4.2.2.3 Developing
an Environmental
Test and Evaluation Master Plan (ETEMP).
This plan is not a formal document, but is comprised of the products from
three separate tasks (Tasks 402, 403,
and 404). Early in the acquisition process, initial
work on these tasks helps build materiel need and performance requirements
documents by identifying basic environments in which the materiel
will operate, and fundamental issues to be addressed during the remainder of
the acquisition process. These three tasks contribute to the TEMP
when they are completed. See figure 1-1. The ETEMP
contains basic guidance/background information not to be confused with detailed
test planning documents explained in Task 405.
4.2.2.3.1 Defining a Life
Cycle Environmental Profile (LCEP), Task
402.
The LCEP describes service-related events and environmental conditions that
materiel will experience from its release from manufacturing to the end of its
useful life. The scope and structure are shown on figure
4-2 that serves as a generalized guide for developing LCEPs for acquisition
programs. Tailor LCEPs to specific programs, treating each line in the body
of figure 4-2 as a survey or questionnaire item to see if it applies to the
specific program for which the LCEP is being developed. It may be useful to
develop a questionnaire based on this LCEP format, taking care to add unique,
system-specific environmental stressors that may not appear in figure 4-2. Fundamental
progress is required on this task early in the acquisition process to influence
the MNS
and the ORD.
The completed LCEP is needed later in the process to help system designers and
evaluators build the TEMP.
It is important to note that the LCEP does not specify design or test requirements.
Rather, it serves as a tailored guide for deriving materiel designs and test
parameters through Tasks
403 and 404, based on performance
requirements.
4.2.2.3.2 Developing
Operational Environment Documentation
(OED), Task 403.
The OED task entails producing two documents. One is a plan for obtaining
data that will serve as the basis for design and test
criteria development. The other is a report that contains those
plans and the resulting data. The plan, the Operational Environment Documentation
Plan (OEDP), provides for two types of data. First, it contains plans for securing
data that have been collected previously and are still valid for developing
the materiel's design and test criteria. Second, it contains plans for collecting
data not available currently, describing how to obtain those environmental data
under realistic operating or field conditions using actual or closely related
systems/platforms. The OEDP and the resulting data (existing and new data) form
the Operational Environment Documentation Report (OEDR).
a. Environmental engineering tailoring tasks are the basic strategy and structure
for integrating environmental considerations into acquisition programs. The
task sequence outlined on figure 1-1 is designed
to meet the environmental effects integration called for in the DoD
5000-series documents. To accomplish this integration, EES personnel
working for government or contractor staffs throughout the acquisition process
help to perform these environmental
engineering tasks to help create a scientifically sound, cost
effective design and test program in the area of environmental effects. This
process, including the hardware test alternatives
indicated on figure 1-1, applies to all materiel
developed for or intended to be used by the military or industry. Detailed task
descriptions are in Appendix A.
