Diploma thesis Enterprise Social Networks - Critical Success Factors is, as its name sug-gests, deals with the area of Enterprise Social Networks, especially implementing into the businesses informatics. Since this is a relatively new technology, terminology, nor the prin-ciples aren't stabilize. That's why I choose target of this thesis to determine what critical factors leading to the success of the implementation Enterprise Social networks into the businesses informatics. These factors I gathered from available literature and published articles by foreign authors, and therefore it was necessary to verify the validity of these factors in the Czech market. The second target of this thesis was the categorization of Crit-ical Success Factors of implementing an Enterprise Social Networks by the Methodology for Adoption and Adaptation of Social Networks. To meet the first target I have to search available works on this topic. Gained Critical Suc-cess Factors I have, by using fusion through cluster analysis, merged into a unique clusters of Critical Success Factors. For them I have found out their relevance in Czech market us-ing questionnaire or interview. To meet the second target, I used the categorization of Enterprise Social Networks, which is described in the Methodology for Adoption and Adaptation of Social Networks. Indi-vidual clusters of Critical Success Factors I have assigned into specific categories using the paired comparisons. The result of this thesis is a collection of 20 unique Critical Success Factors that are accord-ing to the survey identified as relevant in terms of their impact on the success of implemen-tation Enterprise Social Networks into the business informatics. At the same time has been extended Methodology for Adoption and Adaptation of Social Networks by the point of Critical Success Factors view. Chapters 2, 3 and Chapter 4 have interpretative character. Their goals are to identify all the important concepts that appear in this thesis and classify them into context. The second part of Chapter 4 is devoted to research of Critical Success Factors of implementing Enter-prise Social Networks into the business informatics and merging them into unique clusters. Chapter 5 is devoted to verify the relevance of these clusters in the Czech market, and Chapter 6 provides categorization of verified clusters based on Methodology for Adoption and Adaptation of Social Networks.

The aim of this paper is to provide insight into the issue of enterprise social networking (ESN), other collaborative tools , and instruments of social interaction that can facilitate users their individual work tasks as well as contribute to the overall increase in enterprise efficiency.

This study has been conducted with Sirius International as a case company. The investigation has revolved around the weaknesses Sirius, along with the authors, have identified concerning the international collaboration and communication. It was later shown that these problems were based on a low sense of unity in the organization as a result of the lack of knowledge sharing, knowledge management, and spread of organization related information. It was decided to evaluate whether a corporate social network (CSN) could assist in these problems and if so, decide what system would be the most appropriate in regards to the internal needs and requirements at Sirius. The major challenges brought on with an implementation of a CSN, and how to face these, were investigated as a part of the evaluation whether a CSN would be appropriate for Sirius or not. The study showed that a CSN was an appropriate choice for Sirius in order to improve the international communication, collaboration, and unity. The most suitable choice was determined to be Yammer, as it best suited the internal requirements and needs. Along with these results, the largest challenge with an implementation and future use of the system was user acceptance and overall usage of the system. If the CSN is not used, none of the visions, goals, or purposes will be fulfilled. / Denna studie har gjorts med Sirius International som case-företag. Undersökningen har kretsat kring svagheterna som Sirius, tillsammans med författarna har identifierat kring det internationella samarbetet och kommunikationen. Det visade sig senare att dessa problem var grundade i en låg känsla av samhörighet i organisationen och att detta var ett resultat av den låga nivån av kunskapsspridning, kunskapshantering och spridning av organisationsrelaterad information. Beslutet togs att undersöka huruvida ett företags-baserat socialt nätverk kunde hjälpa vid dessa problem och, om fallet var sådant, komma fram till vilket socialt nätverk som skulle vara mest lämpat vid avseende på de interna behoven och kraven från Sirius. Vid undersökningen om huruvida ett socialt nätverk var lämpligt för Sirius gjordes också en undersökning för att identifiera de största utmaningarna med en implementation av ett socialt nätverk och hur dessa skall bemötas och övervinnas. Studien visade att ett företagsbaserat socialt nätverk var ett lämpligt val för att överkomma problemen i Sirius och förbättra den internationella kommunikationen, samarbetet och samhörigheten. Det lämpligaste sociala nätverket för Sirius blev Yammer som bäst täckte de interna behoven och kraven hos Sirius. Tillsammans med dessa resultat visade undersökningen att den största utmaningen med en implementation och framtida nyttjande av systemet var användaracceptans och generell användning av systemet. Om ett socialt nätverk inte används så kan inga av visionerna, målen eller syftena med systemet infrias.
