FMEA has been around for many decades and has a long history as a method to support product designs, manufacturing processes, service, and maintenance. The plain truth is FMEA has the potential to be a very powerful tool to achieve high reliability in products and processes; and when done well, it is remarkably effective. Yet in practice, FMEA does not always achieve the expected results. Based on the experience of over two thousand FMEAs and working with many companies in a wide variety of applications, certain common mistakes show up repeatedly. What are the primary ways that FMEAs can be done wrongly (mistakes made), and what are the quality characteristics that make for effective FMEAs (quality objectives)? These questions are answered in this new short course on FMEA
ABOUT THE TRAINING PROGRAM :-
Failure Mode and Effects Analysis or FMEA is a structured technique to analyze a process to determine shortcomings and opportunities for improvement. By assessing the severity of a potential failure, the likelihood that the failure will occur, and the chance of detecting the failure, dozens or even hundreds of potential issues can be prioritized for improvement.
DESIGNED FOR :-
Sr. Engineer, Engineer, Supervisor and Foreman engaged in maintenance, operation, Store, Supply chain, Quality, Safety and Engineering activities.
OBJECTIVE :-
Employees completing this training will be able to effectively participate on an FMEA team and can make immediate contributions to quality and productivity improvement efforts.

Six Sigma DMADV Approach for Conceptual Design Synthesis of Car DashboardJayesh Sarode
The main goals of Six Sigma need to incorporate
these specific expected outcomes for the program, and
typically fall within the key areas like Quality, Variability,
Productivity. Without attacking quality issues in any process,
all other improvement efforts will certainly come up short. For
doing that Six Sigma implementation can differ widely
between organizations, depending on their individual goals
and operational strategies.
In this project I have successfully applied many design
processes related with six sigma like Identify Customer CTQs/
Customer Survey, develop a Fishbone Diagram, Input
Requirement Checklist, Quality Function Deployment, Design
Concepts (Competitive assessments (Benchmarking), Tradeoff
Analysis, Engineering Analysis - Develop System & Subsystem
Models, Error Proofing and Fixing, Validation, etc.
The aim is to achieve the essential function at the lowest
overall cost while maintaining customers’ optimum value
assurance. In this project I try to develop a such dashboard
design which follow a plastic design guideline, and analyze
and discuss the results to Obtain valid conclusions which
follows a design Standards. Plastic part dashboard is designed
by following Plastic trim design guidelines as well as DFM
(Design for manufacturing) and DFA (Design for Assembly)
guidelines. This project intends to explore the adoption of Six
sigma as a value creation tool. This project presents the basics
of Six sigma and its different phases that can be implemented
to a dashboard for its optimization.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

2. QFD Definitions
Quality Function Deployment is a quality planning method.
QFD ensures that especially (external) customer requirementsQFD ensures that especially (external) customer requirements
flow into the product. The whole process from
development over manufacturing up to sales and service
i i l d dis included.
QFD translates the customer requirements, better the customer
needs into requirements for the design We can say theneeds, into requirements for the design. We can say the
voice of the customer will be translated in the engineering
language, subsequently so refined that it is
d t d bl f th f t i l F thunderstandable for the manufacturing people. From the
design requirements of the product one derives the
requirements for the product parts, from the parts the
process requirements. Finally QFD results in work and
test instructions. In addition, QFD initiates a product and
process data bank.p
QFD and FMEA complement each other.

shipyards of Mitsubishi Heavy in Kobe devised a
quality chart which has become the core of theq y
QFD methodology.
• Strong usage at Toyota & Honda for reduction of• Strong usage at Toyota & Honda for reduction of
the development cycle time (3,5 years vs. 5 years
at GM & Ford)at GM & Ford).
• Use in the USA in the 1980s, first application at

What is the process control method?
Why QFD?
About 80% of all defects during product
f t i d d t d bmanufacturing and product use are caused by
insufficient planning, development and design.
With the first application of QFD at Toyota the total
costs to launch small trucks could be decreased byy
20 % compared to the previous model. The cost
could be cut by half again by optimizing and
refining the approach.
Furthermore the time to production start could beFurthermore the time to production start could be
significantly reduced. (see next slide)
The number of development and product changes
have been reduced drastically.
