DFMEA
Is the application of the Failure Mode and Effects Analysis (FMEA) method specifically to product/service design.
There are 11 steps to complete DFMEA:
- Design Review – Use the product/service design drawings or documents to identify each component and its relation with other components of product/service
- Brainstorm potential failure modes
- List potential failure modes
- List potential effects of failure modes
- Assign the severity ranking which should be based on consequences of failure (1 to 10) (Threat to human life, accident or safety issue is scored 10)
- Assign the occurance ranking (1 to 10)
- Assign detection ranking based on the chance of detection prior to failure (1 to 10) (Easy for detection gets less score – 1, difficult to
detect should be assigend higher score) - Calculate the SOD (Severity x Occurrence x Detection) number or risk priority number (RPN)
- Develop action plan to reduce vital RPNs (Above set baseline)
- Implement the improvements identified
- Calculate RPN again based on improvements. Do mistake proofing.
FEA
is a numerical method for solving problems of engineering and mathematical physics. It is also referred to as finite element analysis (FEA). Typical problem areas of interest include structural analysis, heat transfer, fluid flow, mass transport, and electromagnetic potential. The analytical solution of these problems generally require the solution to boundary value problems for partial differential equations. The finite element method formulation of the problem results in a system of algebraic equations. The method yields approximate values of the unknowns at discrete number of points over the domain.[1] To solve the problem, it subdivides a large problem into smaller, simpler parts that are called finite elements. The simple equations that model these finite elements are then assembled into a larger system of equations that models the entire problem. FEM then uses variational methods from the calculus of variations to approximate a solution by minimizing an associated error function.

FEA
Finite Engineering Analysis
Finite element analysis (FEA) is the modeling of products and systems in a virtual environment, for the purpose of finding and solving potential (or existing) structural or performance issues. FEA is the practical application of the finite element method (FEM), which is used by engineers and scientists to mathematically model and numerically solve complex structural, fluid and multiphysics problems. FEA software can be utilized in a wide range of industries
FEA can help determine any points of weakness in a design before it is manufactured.
PDS Document
Product Design Specification
is a statement of how a design is made (specify the design), what it is intended to do, and how far it complies with the requirements. … Its aim is to ensure that the subsequent design and development of a product meets the needs (or requirements) of the user
IMDS
The International Material Data System (IMDS) is a global data repository that contains information on materials used by the automotive industry. Several leading auto manufacturers use the IMDS to maintain data for various reporting requirements.
In the IMDS, all materials present in finished automobile manufacturing are collected, maintained, analysed and archived. IMDS facilitates meeting the obligations placed on automobile manufacturers, and thus on their suppliers, by national and international standards, laws and regulations.
BOM
A bill of materials or product structure (sometimes bill of material, BOM or associated list) is a list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, parts and the quantities of each needed to manufacture an end product.
ASIL
Automotive Safety Integrity Level
is a risk classification scheme defined by the ISO 26262 - Functional Safety for Road Vehicles standard. This is an adaptation of the Safety Integrity Level used in IEC 61508 for the automotive industry. This classification helps defining the safety requirements necessary to be in line with the ISO 26262 standard. The ASIL is established by performing a risk analysis of a potential hazard by looking at the Severity, Exposure and Controllability of the vehicle operating scenario. The safety goal for that hazard in turn carries the ASIL requirements.

APQP
Advanced product quality planning (or APQP) is a framework of procedures and techniques used to develop products in industry, particularly the automotive industry. It is quite similar to the concept of Design for Six Sigma (DFSS).

SQM
Supplier Quality Manual
CQP
Component Quality
Plan The CQP is a final inspection document, listing any features that can be inspected or
measured on the completed part, and the method and frequency by which those features
are controlled at final inspection. The CQP therefore contains elements from the drawing,
engineering specifications, the control plan, and (where relevant) the aesthetic inspection
requirements. McLaren’s goods-in inspection use the same document.
The CQP is a controlled document; approval is required for each change.

Aftermarket Piece Part Price
The Supplier shall supply components for series production of the Project and for fifteen (15) years after
series production of the Project ceases to enable McLaren to fulfil its post sales service obligations to
its customers.
