Companies are facing an environment which gets more competitive every day. Competition becomes wider and faster (everywhere and all the time). The pace of change is increasing. So does uncertainty. In this context, organizations are seeking how they can develop their agility.
IS/IT has a role to play in the development of the flexibility of the enterprise. IS/IT solutions have usually been built over time in successive generations. Consistency of the overall applications portfolio was seldom a priority. Complexity has grown in the IS/IT landscape, often hindering the development of the business instead of enabling it. Today, Enterprise Architecture appears as a key solution to set the information systems in order and align them to the business strategy.
This involves playing on several fields at the same time from business process optimization to IS/IT simplification. Many approaches exist to help in these areas but none of them is simple and comprehensive enough to provide a general answer to the problem. Our objective is to get the best out of all these initiatives to deliver a public, state-of-the-art, comprehensive yet easy to understand set of best practices to help companies in solving their complexity challenge.
The CEISAR was originally created with the sponsorship of global companies, recognized as key players in their industry. They all consider Enterprise Architecture as a key topic for the success of their operations.
The CEISAR aims at delivering white papers which are practical and ready to use in companies today. Our work is not lab research but hands-on pragmatic findings from the best practices of international companies.
You will discover our white papers are very consistent as they reuse a condensed set of key concepts. We have tried to use as few terms as possible. They are available in this glossary.
Our white papers can be freely downloaded. We welcome any feed-back or contribution to make them even more useful to contact (at) ceisar.org.

CEISAR provides courses for executive training delivered at CentraleSupelec. Our training is based on the small number of concepts we have developped and a rich set of real-life case studies.
You might enjoy sharing with other companies in one of our standard courses. Executive training can also be customized to fit your specific requirements. We are ready to build specific case studies and provide coaching after the training course to make sure our concepts deliver the value you expect on the field.

The CEISAR is involved in the continuous improvment of the courses taught at Ecole Centrale Paris in Computer Science and MIS. Our students get an introduction to Enterprise Architecture featured with examples from international companies. They learn how to model and manage the complexity of the business and its related IS/IT components.
The Center of Excellence in Enterprise Architecture is an applied research center from CentraleSupelec, sponsored by leading international firms and delivering best practices through white papers and executive training in Enterprise Architecture.
Most companies are facing accelerated competition in a globalized context. In this hostile environment, IT is a tremendous opportunity to gain a competitive advantage. Alas, the complexity of IT applications has often grown to an extent where IT is more a constraint to business agility rather than an enabler.
Reducing complexity in information systems is a major challenge for business and IT partners. This requires the ability to speak the same language and identify the fundamentals of the company : business basics, business and organization processes, and the related IT data and services. All this can be shared and reused and forms the heart of the architecture. Having a common architecture accross the enterprise is key to reducing complexity and restoring business agility.
With a myriad of expert groups trying to standardize a part of the equation (from enterprise architecture to SOA, BPM, MDA, ...), it is increasingly difficult to get a complete and simple picture of this topic. Our objective is not to create a new expert group which will add new concepts, rules, and advice. Based on the experience of business and IT professionals and architecture experts, the ambition of the CEISAR is to take advantage of all the good ideas which have been already delivered by existing groups, and make them accessible through standardisation of language, and formalisation of best practices.
The CEISAR delivers white papers and executive training on best practices in enterprise and IS architecture based on real life examples from our sponsors and partners.
We believe in :
Our publications are fully public and available on the web. We hope to link with any institution willing to formalize and develop best practices in enterprise architecture.
