An analysis on Open Source Software Service Level Evaluation using BSEM

Lee et al. (2015) proposed multi purposed evaluation model named Behavior-Structure-Evolution Evaluation Model(BSEM) for the purpose of proposing evaluation framework for open source software service companies based on general corporate valuation model. The evaluation model is composed of three factors. First, enterprise service level of Open source software is divided by Service Area, Service domain and Service Activity. Second, technical reference model of Open source software is divided by Service Area, Open source software technical Domain, Technical Sub-Domain, Open Source Software Name. Third, index of evaluation level is divided by evaluation group, evaluation domain and evaluation item. Therefore, main purpose of this study is to applying BSEM for OSS service companies to adaptability, expandability and objectivity of BSEM. We chose 2 out of 290 OSS service companies and they offer operating system and Database management system services. We applied Technology Reference Model(TRM) for technical domain. At last we applied 21 evaluation indexes for measuring each service level. Also we measured service weight by OSS experts and applied for BSEM model. After whole evaluation indexes are calculated BSEM suggested final service level by showing alphabet from AAA to D and BSEM affords the detailed service level for BSEM user.
