Recognitions
“Through SGL I have got a greater respect and humility for my head job.”
“My journey with SGL has been a very educational journey. With guidance from Jan Petrus, SGL has become a tool that has helped me both privately and in business life. So also in my roles within sports. I recommend everyone to familiarize themselves with SGL.”
“The SGL concept was a fantastic starting point for establishing a common language in the management team. The result was almost conflict-free communication between employees, which released extra energy to strengthen work towards common goals defined in the strategic plan.”
“Being personal and private with your teammates is a challenge for most people. The SGL-groups learn to respond to what they hear. Carefully. Active listening. And gently they say “I have a fantasy of what I hear”. If they manage it is the first step for a winning team. So the key words for this exercise is as SGL brilliantly has stated: Can you accept that you are accepted as you are? In order to be WHO you are?”
Knut Birkeland
“SGL is a brilliant tool to get to know your team and understand they behaviour. SGL is an investment in the true values, people, and this investment will give more back than anything else.”
Kåre Anthonsen
“SGL has provided me with practical tools for bringing teamwork to a really high level. This has been my experience for many years now. For this I am ever thankful!”
Marianne M. Iversen
“Before coming to SGL, I had participated in two different American intensive one-week programmed management training courses. My experience with SGL was very different, and directly relatable to working group dynamics, communication, and balancing group participants for optimum performance in the specific requirements of the tasks at hand. I recommend SGL concepts for development in every type of organisation.”
Bård Sørbye
“Very long experiences (in various large companies) with SGL tools in cooperation with Jan P Hagberg; my mentor. The tools have been very useful in my HR leader career in both private and public sector.”
Steinar Bakken
“My experience with SGL stems from a start up process at the Norwegian Tax Administration in the period 2004–2005. Jan P Hagberg introduced the SGL-method to the team, which was responsible for development and introduction a new solution for tax collection. In the period from 2007 to 2008 the new solution replaced old legacy systems nationwide. The solution, named SOFIE, has since then successfully been handling taxes collected from all persons and companies in Norway.”
Petter Håndlykken
“I use SGL with Jan Petrus as mentor in my artistic work as a musician, conductor, and as a principal and leader in both public and private sector. Through seminars and conversations, SGL has provided me with valuable tools for professional development and renewal. As an artist working in diverse and demanding environments, I can wholeheartedly recommend SGL. It has given — and continues to give — strong motivation for continuous personal growth.”
Arild B. Nielsen
“Jan P. as SGL-coach facilitated numerous discussions on Prediktor's organisation and vision and mission, and had a lots of talks with most people using SGL's Flow-zone diagram in different teams. For nearly 10 years SGL was a very positive factor for development of the persons and company. — In my opinion Jan Petrus made a significant and good contribution to shaping Prediktor into a better company.”
Steinar Sælidfrom The Prediktor History 1995–2024
“I approached SGL to find my “hidden creativity” and to help publish SGL secrets. Along the way I learned how to survive and cope with difficult situations in my life. From my experiences I recommend SGL Tools and insights.”
