Development in Practice

A Structured Summary / May 2026

SGL is a developmental framework built through four decades of practical application in Norwegian knowledge-based organisations. It has been used within institutions such as The Norwegian Tax Administration, Norsk Hydro, Amerada Hess, and large road projects for the Norwegian Public Roads Administration — not as a temporary pilot project, but as a long-term developmental practice. What distinguishes SGL from many leadership models is not simply the variety of methods it contains, but the unique combination of perspectives it brings together:
Practical Validity SGL has been applied, tested, refined, and continuously adapted within real organizations over more than forty years. It is not a laboratory concept or a purely theoretical construction. Its credibility is grounded in sustained organizational experience.
The Power of Language SGL gives people a language for experiences they otherwise struggle to articulate — conflict, personal growth, transitions, relational breakdowns, and organizational tension. Language creates awareness, and awareness creates movement.
Existential Depth SGL is based on the recognition that organizational development involves more than competence, efficiency, and process management. It also concerns human maturity, responsibility, identity, and relationships — because leadership is fundamentally a human activity.
Integration of Individual and Group Dynamics The model connects individual profiles and group dynamics within one integrated framework. Rather than separating personal development from organizational interaction, SGL creates a shared language that links both dimensions together.
Academic Foundations SGL draws inspiration from theology, Gestalt theory, hermeneutics, group development theory, and Scandinavian traditions of organizational learning. It belongs within a Nordic leadership tradition characterized by trust-based leadership, process-oriented development, and collective reflection — an approach increasingly supported by contemporary research.
A Map, Not a Diagnosis SGL is not a psychometric instrument designed to place people into rigid categories. It is a reflective and developmental language system that encourages movement, growth, and self-awareness. Just as a map is not the landscape itself, SGL is not the person — but it can provide direction and orientation.

The Central Question

For organizations considering the use of SGL, the essential question is not whether every dimension can be statistically measured. The more relevant questions are:
  • Does the model foster maturity
    Does it strengthen responsibility and accountability
    Does it help organizations address realities they previously lacked language for?
    Can it withstand critical reflection?
    Does it contribute to human and organizational growth?

SGL has answered yes
— in practice — for over 40 years.

CONCLUSION

In this context, SGL is not an “academic theory”, but a legitimate and integrated practice and reflection model for human and organisational maturation.
