Integrating software change request services into virtual laboratory environment: Empirical evaluation
This article presents an approach to integration and evaluation of software change request (SCR) specification services in an educational environment. The educational environment, a virtual network laboratory, VNLab, and its extension with services for specifying SCRs, are described. There are three services for SCR specification implemented in the described environment. These services are: paper form service, Web form service, and service integrated within the context of running application. The last service is based on developed software utility called SCRSpecifier (Software Change Request Specifier). After the services' description, the results of a conducted experiment are presented. The main goal of the experiment was to discover possible advantages and disadvantages of described SCR services and to compare them. The analyses of the data, collected during the experiment, provided the evidence that implemented services are useful to students and personnel responsible for maintenance of described educational environment.  2011 Wiley Periodicals, Inc.
