Aerospace/Defence 8-D Problem Solving - based on AS13000

In an effort to ensure that problems only ever occur once; and are then fixed permanently; the global aero-engine manufacturers have collaborated to create AS13000 which is a standard customised for the industry using a step-by-step problem solving methodology popularized by Ford Motor Company and Toyota in the 80’s.

Known as ‘8-D problem solving’ it is a highly structured method that solves problems by identifying and correcting the root causes of events as opposed to simply addressing their symptoms! The methodology is structured into eight disciplines, emphasizing a cross-functional team synergy and the use of designated quality tools and techniques.

By the end of this 2-day interactive course participants will understand ‘disciplined’ problem solving and be able to facilitate and document value-adding problem solving exercises using the Eight Disciplines (8-D) method to respond to a customer request for corrective action in conformity to AS13000 requirements.

Assessment of learning is achieved through structured exercises and an aerospace Case Study.The tutors provide feedback and advisement to ensure that risk-based thinking, ethical behaviour and associated best practices are fully understood in the context of the aerospace/defence industry.

  • All participants undertake an assessed Case Study to test their application of 8-D
  • A 1½-hour written examination is available as an option at the end of Day #2 based on their analysis of an Aerospace Case Study.

The 2-day course is highly interactive and uses Aerospace Case Studies and group exercises. The course timings are -

  • Day #1: 08:30 - 17:00
  • Day #2: 08:30 - 15:30
  • Day #2: Written exam (optional) or Team Case Study - 15:30 -17:00

On-site coaching (option)

TEC Transnational also offer on-site coaching session delivered over 1- or 2-days as an option. We facilitate an 8-D problem solving session with the organization’s Champion, Team Leader and designated team members.

The course is delivered over two consecutive days with continual assessment and feedback provided by the tutors.In addition, there is an optional 1½-hour written examination is available at the end of Day #2.

Details/quote

Champions/Sponsors, Facilitators and Team Leaders who must respond to customer requests for corrective action using the 8-D process and communicate progress using the 8-D Problem Solving Form of AS13000.

Particular emphasis is placed on empowering the individuals who will be facilitating 8-D workshops.

Apart from these nominated ‘Facilitators’ all persons participating in the cross-functional problem-solving team will benefit from attending this course.

The 8-D problem solving methodology covers three key stages of correction and corrective action.This course empowers participants to -

  1. Act rapidly to put immediate containment action in place to protect the customer (stop the bleeding!)
  2. Find and fix the root cause with a permanent corrective action on all current product
  3. Prevent the recurrence of the problem in the future by identifying and implementing preventive action anywhere possible within the organization

Organizations need to empower a Champion/Sponsor, Facilitator(s) and team members in the 8-D problem solving methodology in line with the requirements of AS13000 and the soon-to-be-published IAQG 9136 standard.

Organizations offering 8-D problem solving embedded in their QMS will have a distinct competitive advantage.

TEC's 2-day course will empower all of the organization’s cross-functional team members to undertake value-adding 8-D problem solving and communicate progress to the customer concerned using the 8-D Problem Solving Form of AS13000.

The individuals attending will learn how to use a set of powerful quality tools for both data collection and analysis.In addition they will be able to plan and facilitate 8-D problem solving exercises.

A 1½-hour written examination is available as an option at the end of Day #2 based on the analysis of an Aerospace Case Study.

Alternatively, the organization chooses to provide a real problem for solution. This then replaces the illustrated case study and the written examination.

Larger teams might benefit from our in-house courses. Fill out the form below and we will contact you with further details.
