Welcome to EDC51

EDC51 Group is a UK London-based international consultancy. We specialise in leadership assessments, development and team cohesion. Our clients are companies that see the role of authentic leaders and cohesive teams as part of their strategic competitive edge.

Our work is rooted in three main pillars—relational psychology, subjective experience and group dynamics. We see your people in the context of your company culture, vision, values. Here is what really makes our work unique and one-of-a-kind.


We work not only with cognitive and behavioural level but also affective, experiential and phenomenological ones. This involves shaping of your team’s relationships and subjective experiences.

Our assessments, leadership development and team cohesion work—whether we are working with individuals or entire teams—are informed by theories, techniques and practical experience from classical, integrative and relational fields of transactional analysis, coupled with psychodynamic, psychoanalytic, object relations and gestalt approaches.

We also base our work on theories and practice of group dynamics acquired in psychotherapeutic, counselling, organisational and corporate consulting environments.


Leadership is not solely about behaviour and mindset. It is predominantly about the attitude, relating and trust.

We facilitate your leaders’ development on all these levels. This means that we not only develop your leaders’ skills but also shape their attitudes.

We at EDC51 feel that leadership potential is strongly influenced by potential to develop meaningful professional relations, trust, individual’s professional needs, and the ability to build a performing and cohesive team-as-a-whole.

Team Cohesion

Team's performance is a direct outcome of team cohesion. And team cohesion is a manifestation of leadership effectiveness.

Focusing on the team-as-a-whole is the main vehicle of increasing individual's performance, engagement and devotion. It is not the other way around!

The success of the company predominantly depends on the success of the team and how the team is led, not solely on the success of the individual.

This is why we complement development of individual leaders with development of teams-as-a-whole. Both our assessments and our development programmes utilise multiple group dynamics theories and techniques.

We have developed a unique set of assessments that evaluate the level of group cohesion of your team over time.


EDC51 developed a unique set of Subjective Experience Assessments (SEAs). SEAs not only indicate leader’s subjective experience in the workplace, but also evaluate team cohesion, its integration with company culture, values, vision and so much more.

SEAs are an answer to the limitations of common psychology, feedback and personality assessments, which underestimate leaders' subjective experience, their needs, ambitions and their integration with the team, company culture and wider professional environment.
