Karer Consulting

We increase the added value of your IT.
Companies are more dependent on IT than ever before. Our consultants support your IT to increase its added value within the company. They can then align the IT of your company to your particular requirements. Things are not just left as a concept, but there is also support for actual implementation. Through the seamless integration of business and IT, our consultants create genuine added value.



SIAM - Service Integration and Management
More and more companies are deciding to outsource IT services to a range of IT service providers in order to optimise their business processes and benefit from the best-of-breed services of the chosen providers. Service Integration and Management (SIAM) is a management method that can be used in such multi-provider environments to manage increasing complexity. With a SIAM model, you have an end-to-end view of the services and clearly defined and assigned responsibilities. The approach applies established standards for orchestrating service delivery and integrates IT services from multiple providers to ensure they are seamlessly integrated and deliver business benefits.

"This book has been created together with companies from a wide range of industries. The book is used best as a practical guide for Management and as a reference (shortcut) for building and implementing professional Service Integration."
