Belief and people

Efficiency is wider than cost.

You have to look at what you get out of what you put in – comparing only the inputs (like cost) will just drive all industry players in the same non-differentiating direction. Tefficient believes in strategy and differentiation as the key to competitiveness, hence a costly initiative can be efficient if it proves to provide sustainable differentiation. But it needs to be measured.

In Tefficient’s view, benchmarking is a diagnosis and filtering tool – which should represent no more than 20% of the effort. The remaining 80% should be used to find the root causes to the diagnosed issues – and find the solutions. We believe that too many telecom players waste effort in the benchmarking & diagnosis phase, leaving the organization so “benchmark fatigue” that it can’t deal with the issues. If so, the project is a waste of time, money and people.


Fredrik Jungermann, Managing Director, has more than 20 years of experience in measuring, comparing and improving the competitiveness of telecom operators.

Fredrik founded the operational efficiency benchmarking practice in Nokia in 2002. He led the development of the practice from a mobile operator benchmark into one that also covered fixed and integrated operators. As the leader of the dedicated team, Fredrik was involved in more than 300 operator benchmarks globally.

In 2011, Fredrik felt that his expertise could benefit the telecom industry more effectively if provided independently. He resigned from Nokia and founded Tefficient.

Fredrik is passionate about efficiency and can’t really accept time, money, resources or opportunities being wasted. He features an engaging and motivating communication style. Within his area of expertise, Fredrik is a respected thought leader. He speaks in international conferences and is a key contributor to many papers used as ”heads up” by executives globally.

Before building his expertise in how to measure, compare and improve competitiveness, Fredrik had operational sales roles and professional services management roles in Nokia (based in Denmark and the Netherlands). He started his career as an engineer at TeliaSonera in Sweden. Fredrik is a Swedish national, born 1965, holds an M.Sc. from University of Lund, is married and lives with his family of 5. He is a practical guy who loves outdoor life.
