Environmental Engineering Specialists (EES). EES are government or industry professionals in the acquisition process whose experience allows them to support Program Managers by helping to perform the tasks in Annex A. Their backgrounds may span many scientific/engineering disciplines. They already exist in Government and contractor agencies involved in the acquisition process (e.g., serving as design, test, and reliability engineers/scientists). Several EES of different backgrounds may work on an integrated product team (IPT) at one time or in sequence throughout the program, employed by or on contract to agencies of the services as appropriate at the time. Their work is documented and passed on through the products of each successive task.
4.2.1 Roles of Environmental Engineering Specialists
EES from agencies within and on contract to government agencies support Program Managers throughout the acquisition cycle. EES are assigned by agencies that are responsible for performing the tasks outlined on Figure 1-1 and explained in detail in Part One, Annex A. EES should be involved early in the acquisition process, serving as

critical sources of environmental effects expertise and as technical facilitators throughout the entire acquisition process as part of an IPT. As shown on Figure 1-2, EES form facilitating bridges among design and test needs of Program Managers and technical procedures used by testers. The primary mechanisms for accomplishing environmental engineering goals are the tailoring tasks described below.
4.2.1.1
Single Point Noise Control.
Define the single point, providing an optimum control position in the chamber or progressive wave tube.
4.2.2 Environmental Engineering Tailoring Tasks
4.2.2.1 General
- 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 Annex A.
- b. As indicated in 4.1, above, the primary benefits of performing these tasks come from the technical information and structure they provide for the CONOPS, SRD, ICD, CDD, CPD, SEMP, 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, and 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 SEMP. This integration helps 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; 4.1.2; and Annex 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, Annex 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 ET EMP 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 Figures 1-4a & b that serve as a generalized guide for developing LCEPs for acquisition programs. Tailor LCEPs to specific programs, treating each line in the body of Figures 1-4a & b 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 on Figures 1-4a & b. Fundamental progress is required on this task early in the acquisition process to influence the CONOPS, SRD, ICD, CDD, CPD, SEMP, and TEMP. The completed LCEP is needed later in the process to help system designers and evaluators build the TEMP. 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).
4.2.2.3.3 Developing an Environmental Issues/Criteria List (EICL), Task 404
The EICL is developed from the LCEP and OEDR. It contains a list of tailored issues and criterion, complete with appropriate criterion levels for the materiel being acquired. Also, it includes rationale and assumptions for how environmental effects issues and criteria were derived. This rationale aids designers, developers, and assessors as they revise criteria when materiel deployment concepts and designs change.
4.2.2.4 Preparing a Detailed Environmental Test Plan (DETP), Task 405
Developers, evaluators, assessors, and testers prepare detailed environmental test and evaluation plans in various levels of detail (e.g., Independent Evaluation Plans through Detailed Test Plans), consulting with on-board EES as necessary. These detailed plans serve as the primary means for calling out specific laboratory and field tests, test sites, instrumentation, procedures, and criterion levels for environmental tests. The DETP may stand alone as an environmental test planning document or may appear as a subset of a larger test plan. Quite often, the highest level of detail in these plans appears in standard test procedures referenced in those plans. For environmental laboratory tests, detailed methods are in Part Two of this standard.
4.2.2.5 Preparing an Environmental Test Report (ETR), Task 406
Preparing an Environmental Test Report (ETR), Task 106. Environmental test reports are produced at various points in the acquisition process. Specifications for conducting development and operational tests, and formats for resulting reports are provided by development and operational test agencies. This task pertains mainly to the results of materiel tests performed in environmental testing laboratories. The ETR defines the test purpose, lists test issues/criteria, lists or describes test equipment/ facilities/instrumentation, explains the test design/set-up, contains detailed test data/logs, provides failure analyses, and interprets test results. The laboratory ETR is appropriate for design evaluation tests, operational worthiness tests, and qualification tests. Data from these laboratory tests serve as early warnings of unanticipated deviations from performance requirements. They support failure analyses and corrective actions related to the ability of materiel to withstand specific environmental conditions. These laboratory test data do not serve as substitutes for development or operational tests conducted in natural field/fleet environments.
