Mission statement / consulting philosophy

Collusor is a networking management consultancy, working as facilitator or external resource in change processes to help clients reach new business-oriented, organisational or developmental goals. To obtain the agreed strategic direction of the client’s organisation, we focus primarily on organisational and management improvements, as well as leadership development.
Collusor also acts as an external resource in processes where clients aim to improve their abilities in any strategic direction, to help innovation and to benefit from cultural adjustments.
Collusor always bases its operation on business ethics and social responsibility. For every project that reaches a turnover of NOK 100,000 (approx.  € 11,500), Collusor purchases six months supply of specially developed nutritional food for a child in selected areas of the world, offering the client the opportunity to continue the donation.

Credentials (short description of some typical assignments)

We have supported the company with management and specialist services for several years. In the process from a state owned monopoly to the largest of three major wholesalers, several managers have drawn upon our company as an external resource and sparring partner. We have been involved in recruitment, coaching, revitalising and management development, helping the organisation to succeed through the changes.  

A Norwegian electronic manufacturer was acquired by an international enterprise and we have performed several top management recruitments and been coaching managers in different situations. They have all shown ability to increase the activities and meet the required performance and results of the organisation.

We were project managers in an extensive change process. The industry was conservative, government directed and monopolised with little or no willingness to change. The programmes included specific training for the top and middle management as well as board members. We performed work-shops with all employees to implement new thinking and to support management and organisational development. The changes in culture, attitudes, focus, working habits etc. challenged the organisation and the entire industry. The processes led to new strategies and continuous changes putting the branch organisation in a position to provide new and relevant services to the members and is also representing all the market actors towards the political and legal authorities.  

The owners and leading partners in a major civil architecture firm were rapidly entering retirement age. We created a process with the owners and the management to establish a new strategic consciousness about the company's future. A new and enlarged management team was established and through processes the partners developed individual management style and strengths. The assignment succeeded and both previous and new owners are satisfied with the new situation. The company has proved its existence and competence by winning large projects to be developed over the coming ten years offering further opportunities for growth.

A small and specialised industrial plant was becoming “non-core” for the owners due to industrial changes. The process was to establish the unit as a service provider to all competing chains in the market and preferably get them all as equal part owners. All the chains were parts of international conglomerates with little experience in the country. It seemed impossible to find a new ownership at the time, but the unit became well established as a service provider to all the chains and many of the independent operators in the market.

The organisation which operates in the safety and rescue of people, as well as equipment faced two periods of difficulty few years apart leading to new strategic situations and a potentially dramatic fall in income. During these difficult operational circumstances, we supported the organisation with investigations and recommendations, working closely with management to attack and resolve the situations. We operated as sparring partners for CEO's during the transition periods, and in both situations we helped the organisation find ways to compensate for the loss of income. The organisation is now running very satisfactorily.

For 15 years we have been working with outplacement, primarily on the executive level, and as executive coach for managers in a wide variety of industries and organisations. The processes have been very personal and offering individual and intensive feedback throughout the programmes. Most of the participants consider this a very important change and as an important period in their life, have obtained a clear picture of their resources and newly acquired abilities to handle difficult situations more successfully.
