Effective implementation (in terms of time, cost, utilization of human resources, etc.) of information systems operation is a strategic issue in today's time when business processes are integrally aligned with the informatics. Currently, costs associated with software support and maintenance represent more than 90% of total costs. Software maintenance is a set of activities needed for cost-effective support of IT solution. IS / IT Center of excellence (COE) do not cover the area of software support and maintenance, there is no formalized methodology or procedural framework for COE for support and maintenance -- in reality, it means missing processes and procedures for creating it, management and evaluation of it. Moreover, there are missing recommendation about organization structure, services to be provided and overall continuous improvement. Therefore author proposes his own solution by definition and implementation of center of excellence for support and maintenance and its sub-centers of excellence for support and maintenance of particular applications. Current ontology of support and maintenance does not capture the necessary components and links -- namely missing management, planning and effort estimation views. Therefore author proposes his redefinition and enrichment of ontology of organizational structure about elements of competence and sub-competence center, typology of tasks (management, maintenance), and their management - estimating, planning and realization. In his work, Magne Jorgensen formulated conclusions that 83 to 84% of all estimation is done by pure expert estimates and estimating models are not used basically due to their complexity. Based on extending PERT formula about quality of estimator and historical experience, author introduced his simplified, easy to use approach to effort estimation in software maintenance. Both introduced formulas were verified in sub-competence center for supporting mortgage IS with significantly better result than only pure PERT estimate (98.8% and 91.8% against pure PERT 90.1%). In conclusion, author discusses the benefits of the implementation of center of excellence for support and maintenance and sub-centers of excellence for support and maintenance of particular applications, and overall fulfilling of thesis scope.

Bakgrund och problem: Det har riktats kritik mot den traditionella ekonomistyrningen vilket har gjort att moderna styrmetoder och verktyg växt fram för att komplettera ekonomistyrningen. De faktorer som tvingat fram den moderna styrningen går även att se i musikbranschen. Detta, tillsammans med att ekonomistyrning i musikbranschen generellt sett är outforskat, gör att det blir intressant att undersöka hur skivbolag i musikbranschen använder sig av en traditionell ekonomistyrning eller modern verksamhetsstyrning. Syfte: Syftet med denna uppsats är att genom att undersöka två skivbolags ekonomistyrning kartlägga hur ekonomistyrningen karaktäriseras utifrån traditionell ekonomistyrning och modern verksamhetsstyrning. Metod: Metoden som använts vid denna studie är kvalitativ. Vi har genom fallstudier hos två skivbolag undersökt och skapat oss en förståelse av ekonomistyrningen i bolagen med hjälp av semi-strukturerade intervjuer och kompletterande frågor via mail.   Slutsats: Det går att se att skivbolagen övergått delvis till en modern verksamhetsstyrning men att det alltså finns en blandning mellan användandet av traditionella och moderna styrmetoder och verktyg. / Background and problem: Criticism has been raised towards the traditional management control which pushed forward modern management methods and tools to complement management accounting. The factors that pushed out this modern management control are possible to see in the music industry aswell. This, together with the fact that management control in the music industry has a research gap, makes it interesting to examine how record labels in the swedish music industry are using traditional or modern management control. Purpose: The purpose of this thesis is to through the examination of two record labels create an understanding of how the management control is characterized through traditional or modern management control. Method: The method used in this study is qualitative. We have through a multiple-case study at two record labels examined and created an understanding of the management control in the companies with the help of semi-structured interviews and complementary questions through mail. Conclusion: It is possible to see that the record labels has partly moved to modern management control but also that you can see a mix between the usage of traditional and modern control methods and tools.
