Oliver F. Lehmann Project Business Training Reviews 

Great experience

The Perfection in every aspect

The virtual sessions and workshops have been very timely and enriched. Oliver Lemann always delivers with high value, experience and expertise. The good thing about the experience is that you get to have an evidential record of progress and learning in a dashboard. You also get to share your experience and progress with the LinkedIn community for global visibility.

I have completed Oliver Lehmann’s Project Business Professional (PBP) programme and passed the certification exam. The course helped me develop a stronger understanding of the business side of project management, including commercial considerations, contracts and collaboration between organisations. I found the learning experience valuable for my professional development. Thank you, Oliver, for your guidance and support.

I am ver y much satisfied with the course and preparartion. As a attorney ay law, I deal with many conflicts created for the most part by defective contracts.

It was enlightening and resourceful. Mr Oliver possessed a candid knowledge of project business management and I loved it ☺️
I strongly recommend his pbp course

I recently achieved my PBP certification and I am very happy with the experience. The Project Business Compendium and seminar materials are clear, practical, and useful for real project work. The program covers contracts, commercial risks, cash flow, legal points, and the people side of projects across company borders. The exam was fair and it helped me understand project business much better. Oliver F. Lehmann and the Project Business Foundation have built something truly valuable. I highly recommend this certification to any project manager who works with external customers, contractors, or contracts. Thank you, Oliver, for a great program.

I enjoy the seminar very much. Innovative, to the point, scientific and very helpful for my business.

It´s a great experience because we can evaluate kowledge in each sesion by completin the modules of questions

Program: Meet the Project Contractor of the Year Award (PCoTY) - why this award, who it is for, and how to take part

This program allowed me to confirm my dedication to help identify and recommend companies and experts for the quality of work they provide that led to their current ranking of success.
This program offered a refresher for knowledge already known by project managers but sometimes ignored due to project situations and power play issues.
Much appreciated the engagement to compare competency and skills. I will add the link for the certification registry on my LinkedIn so clients can confirm my certifications earned over the years.

WITH MUCH APPRECIATION.

Smooth experience

I took the PBP Certification training in 2025, and entered Oliver's world... which has expanded mine!

The learning that I experienced answered so many questions that I've had in mind over the years. I consider the PBP a welcome expansion of my PMP. Thank you!!

He puts always a lot of effort in his classes and explains everything in detail and throughly. I recommend attending the classes and listening to his pieces of advice.

Excellent, insightful and pragmatic sessions

A most welcome augmentation to my PMP, and I couldn't ask for a more knowledgeable and experienced instructor than Oliver. He truly is the best.

The versatile knowledge Oliver transfers is practice and business oriented for real life application and understanding.

Oliver Lehmann is an excellent trainer with broad knowledge and experience. The PBP course is absolutely helpful and gives another point of view.

I have worked with projects for almost 30 years, and it is not often I attend a course that genuinely changes how I think about projects.

Oliver's Project Business Seminar did exactly that.

The seminar was professional, engaging, and packed with valuable insights. I learned a lot and gained a much better understanding of the business side of projects, beyond the traditional project management disciplines.

I successfully completed the PBP certification afterwards and can highly recommend both the seminar and Oliver as a trainer.

What stands out is not only Oliver's knowledge, but also his willingness to share it and support project professionals in their continued learning.

Thank you for a great experience

Having participated early on, I have always found Oliver to be an outstanding trainer. His experience, knowledge, course structure made the material easy to understand. Ample time was given to explain concepts necessary, and key points driven home. I would highly recommend Oliver and the PBP certification to demonstrate your commitment and knowledge base as a practitioner in the field.
