Practical Skills for Investigators (MEDA)

TS05 | 4 days

Conducting a successful Human Error based investigation can be complex. Despite all efforts, a Just Culture and unequivocal objectivity, it is still difficult to establish the root cause of an error and to provide your leadership team with a clear picture of what is really going on. All too often the same mistakes keep happening – so what is going wrong? How can you truly understand why errors are occurring and develop effective recommendations to help stop them happening again?

‘Practical Skills for Investigators’ will help you understand root cause, and enable you to effect changes that result in improved operational efficiency and ultimately a better bottom line.

How will this course benefit me?

This practical, skills-focused course gives you the complete skill set and techniques to confidently conduct effective MEDA-based investigations and present your findings. You will be given the opportunity to develop your interview skills using the latest thinking in cognitive interviewing techniques, You will also develop improved investigation planning, preparation, and data analysis in your inquiries. One area we consistently find weak when reviewing investigations, is the development of effective, efficient and sustainable recommendations; this will form a key element of the course.

You will be taken through a series of evaluated exercises both in syndicates and as individuals and will have ample opportunity to apply skills learnt in the classroom in ‘real-world’ scenarios. Emphasis is placed throughout the course on the human element of error and the complexities involved in its investigation, with particular emphasis on our unconscious biases.

By completing this course, you will be able to:

• Increase your contribution to your organisation’s safety and efficiency standards
• Reduce your exposure to risk and risk-provocative situations
• Provide cost savings through reduction of unnecessary rework
• Improve reliability


Key areas of focus

• Overview of Human Factors and Error Management, specifically error, rule-breaking and defences against them
• In-depth look at the Boeing Maintenance Error Decision Aid (MEDA) investigation tool
• Investigation planning and preparation
• Interview skill including rapport building, opening, conducting and closing interviews
• Collecting suitable data as evidence
• Analysis of the data and drawing conclusions
• Development of effective, efficient and sustainable interventions 
• Extensive real-world based exercises including a final mock investigation

Note: This course is identical to our TS30 course, but is based on the Boeing MEDA report form and taxonomy. If you do not use MEDA please book the TS30 course.

Is this course right for me?

This is a practitioner level course, ideally suited for new and prospective event investigators, typically:

• Quality Assurance Staff
• MEDA Coordinators
• Engineering Staff who are conducting investigations

This course would also benefit:

• Regulatory Authority Inspecting Staff
• Newly-promoted Maintenance Managers

This course is also suitable if you wish to gain a deeper understanding of ‘Just Culture’ within your organisation or if you are experiencing resistance with engagement in an effective reporting Culture.


Delegates should previously have attended training in Human Factors and be within date (2yrs) for their refresher training. A basic understanding of Just Culture principles will also be beneficial.

Frequently asked questions

Is this course suitable for aircraft crash investigation?

No, this course does not address issues such as casualty notification, media management and wreckage recovery. This course is designed to address the needs of investigators tasked with eliminating system failures and near misses initiated by your internal safety reporting systems.

How does this course link to Human Factors training and eliminating human error?

A thorough understanding of Human Factors is essential to ensure that your investigators make the causative links between failures and the safety recommendations they propose. Too often we see interventions that are ineffective, inefficient, or unsustainable, and as a result problems come back or the burden brought by the recommendation is greater than the original issue.

Does this course cover root cause analysis?

Yes, however, the term Root Cause is often misunderstood, which often leads people to mis-identify or over simplify the causes of the originating issue. This course explains the misconceptions caused by the term and the benefits of a human centric causal analysis. The course covers a systematic process that guides investigators through 
investigation planning, data gathering and debriefing, recommendation development, and delivery of a final report.

How much focus is on the Boeing Maintenance Error Decision Aid (MEDA) taxonomy?

This course includes an in-depth look at the MEDA taxonomy but MEDA is not its primary focus and you will need to attend separate training for a full induction into that tool.
