SLIDES AND RECORDING – ASQ RRD SERIES: THE FUTURE OF XR (CROSS/MIXED REALITY) IN BUSINESS: INNOVATIONS, STRATEGIES, AND USE CASES

On Thu, Mar 14, 2019 Philip Volna and Denis Potapenko presented “The Future of XR (cross/mixed Reality) in Business: Innovations, Strategies, and Use Cases”

As the Augmented Reality (AR) / Virtual Reality (VR) / Mixed-Crossed Reality (XR) industry expands, there are a lot of opportunities for both big companies and startups to realize a competitive advantage. Real life problems that once were out of reach can now be tackled with advanced digital technologies. For some, these opportunities can become a life mission while for others they will become strong selling points. During the webinar, we will highlight some of the market opportunities and strategies that we have identified and have been engaged in. Examples of AR/VR/XR use cases will be shared to help innovators generate creative ideas on how to take advantage of this quickly expanding market. We will share what appear to be the fastest growing industries adopting this approach and how gaining the right perspective can overcome formidable challenges while at the same time improving profit margins.

Below a link with the slides of this webinar.

SLIDES AND RECORDING – ASQ RRD SERIES: TESTING TECHNIQUES – MAKING EVIDENCE BASED DECISIONS

On Thu, Feb 14, 2019 Timothy M. Hicks, PE and Roch J. Shipley, PhD, PE, FASM presented “Testing Techniques – Making Evidence Based Decisions”

Testing is a very broad topic. Various types of tests are performed throughout the life cycle of a product or component. These tests range from:

Pre-production testing
Audit testing to verify production intent
Reliability testing once a product is in production
The focus of this presentation will be on reliability testing and to provide an overview of the types of tests that are available, what specific tests are utilized for, and provide examples of successfully implemented tests.

When a product does not perform as expected, the process of finding the reason why is commonly referred to as failure analysis. Materials and components do not really “fail”; they may fracture when overloaded or when corrosion is involved due to an aggressive environment. These failures can be attributed to either design related issues or inappropriate application or use. Therefore, the only “failure” is a failure to meet expectations. Materials characterization and testing is a critical element of the failure analysis process. Categories of the materials characterization testing techniques that will be discussed include:

Plastics / Polymer Analysis
Metals Analysis
Coatings / Surface Analysis
Corrosion Analysis

ASQ RRD Series: Understanding Risk to Improve Management Systems

May 9, 2019 12:00 PM EST

Speaker: Fatema Tuz Zohra

Registration URL:  https://attendee.gotowebinar.com/register/189042730201175819

Understanding Risk to Improve Management Systems is a critical element of Reliability. The short definition of Reliability being “Mission Effectiveness”, this presentation speaks to the ability to ensure the effectiveness of the processes that manage the development and delivery of products/services through an appreciative analysis of the management systems. ISO 9001:2015 is the standard used to implement an effective management system. The objective of the presentation is to elaborate on the core-concepts and implementation of Risk-Based Decision Making. Additionally, developing a culture of risk based thinking (RBT) is a strategic imperative for an organization pursuing continuous improvement.
