Who We Are

For over 33 years, Professional Development has been at the forefront of innovation in the Irish training market.

We have always had a strong reputation for training within process improvement and project management.

With a sharp focus on lean six sigma training in the past decade, we introduced custom-designed lean six sigma courses, leading to national and international certification.

The instant popularity of these courses and growth in demand for a dedicated resource for those seeking training and qualification in lean six sigma led to the introduction of LeanSixSigmaTraining.ie.

Our Team

Experienced, certified black belt trainers deliver every one of our lean six sigma training courses.

We choose our trainers as much for their active experience leading process improvement initiatives as their qualifications. We believe that real-life experience is key to delivering training that makes an impact.

Our Values

The calibre of qualifications we offer is important to us. However, we are equally focused on backing up those certifications with practical training.

Our goal is that you will leave our courses with the ability to apply lean and six sigma approaches in your own environment with confidence and skill.

We blend active, practical learning with theoretical knowledge to create a learning environment that supports this goal.
