Life Cycle Environmental Profile (LCEP)
What is a Life Cycle Environmental Profile (LCEP)?
An LCEP is an analysis of the environmental stresses likely to be encountered during the entire life of a product, from manufacturing to end of life. It serves as an input for a Environmental Issues/Criteria List (EICL) which is a collection of justified environmental parameters for design and product test. These stresses include those found in logistical, tactical, and operational phases.
This process is valuable for both military and commercial products in that it provides a basis for a product that will meet customer requirements and prevent costly product recall and redesign.
CVG Strategy’s Life Cycle Environmental Profile (LCEP) are compliant with MIL-STD-810 Task 402. The purpose of an Life Cycle Environmental Profile is to document the decisions, choices, and plan for a particular product or family of products. MIL-STD-810G states clearly that there is a decision tree to be applied to justify choices and tailoring of test parameters. This profile is the document we use to define the Natural Environmental Characteristics, Item Platform Characteristics, Platform Environments, and Design Requirements which will yield tailored Test Procedures.
When we prepare an LCEP, we will evaluate the following:
- Product Engineering Plan
- Customer requirements documents
- Sales input on desired performance characteristics
- Product brochures and white papers
- Engineering review of product capabilities
- Map of product from factory to fielding
- Geographic plan
- Similar products (competitive research) life cycles
Having an LCEP helps to define where and how a product is to be used and supported. It also becomes a story board of environmental stresses and provides parameters for design and evaluation of the product’s survivability.
LCEP – Outline
- Mission Profile
- Incorporated Documents
- Transport (non-operating or operating)
- Anticipated Logistical & Operational Events
- Service Life Analysis
- Environmental Factors
- Climatic Operational Areas
Environmental Issues/Criteria List
Once an LCEP is prepared, its parameters, along with customer specifications and measured data serve as inputs to the Environmental Criteria/Issues List (EICL). The EICL is a living document that provides parameters for design specification and tailored test and evaluation severities. Each parameter should provide justification and source data so that its validity can be reviewed as the document evolves. Of inputs to this list measured data is considered to have the highest validity.
Product Test Plan Matrix
Once environmental stresses have been identified a test matrix can be generated which will identify relevant test methodologies. The matrix normally includes:
- Method (Element)
- Tailored Parameters
- Operational or Storage Test Item Configuration
