Purpose The purpose of this paper is to identify the relationships among absorptive capacity (AC), organisational culture (OC), and software process improvement (SPI) implementation success based on capability maturity model integration (CMMI). Specifically, the aim of this study is to understand the roles of potential and realised AC in SPI success. Design/methodology/approach This study proposes a research model and examines the relations among firm AC, SPI success, and OC. The authors surveyed 56 Taiwanese firms that adopted the CMMI-based SPI programme and received official certification. Findings The findings indicate that potential and realised AC have significantly positive effects on SPI success. In particular, realized (AC) partially mediates the effects of potential AC on SPI success. Furthermore, the effects of potential and realised AC on SPI success are significantly moderated by the adhocracy and hierarchy OCs, respectively. Research limitations/implications Given that the scope of this empirical study was limited to Taiwan, the findings might lack generalisability; however, this provides an opportunity for future research. Originality/value This is the first empirical study investigating the influence of AC on CMMI-based SPI success. The proposed research model also examines the moderating relationships of two types of OCs, namely adhocracy and hierarchy, on AC (potential and realized) and SPI success.

PurposeSoftware process improvement (SPI) is a knowledge activity that is critical to the excellence of information system development. This study observes two knowledge gaps in the quest for SPI success and proposes a research model that integrates existing knowledge antecedents to address these gaps. Based on organizational learning theory and the dynamic capability view, the proposed model consolidates a firm's absorptive capacity (AC), learning ability in terms of exploration and exploitation and knowledge sharing (KS), and it examines the contextual relationships among these knowledge antecedents on the path to SPI success.Design/methodology/approachA quantitative research design is implemented to examine the model with a sample of 138 SPI-certified organizations in Taiwan and Mainland China. The partial least squares (PLS) technique is used for the data analysis.FindingsThe results reveal the following findings. First, AC triggers the effect of exploration/exploitation on SPI success. Second, KS fosters exploitation but has an insignificant influence on exploration. Third, KS can promote AC, and it serves as the sourcing mechanism for all of the knowledge antecedents. Overall, an integrative set of knowledge learning routes is presented in guiding software firms on the way to SPI success.Originality/valueIn addition to identification of the two knowledge gaps, this study advances the authors’ understanding by comprehending the causal associations of the four knowledge antecedents on the way to SPI success.

Currently, standard semitransparent photovoltaic (PV) modules can largely replace architectural glass installed in the windows, skylights, and facade of a building. Their main features are power generation and transparency, as well as possessing a heat insulating effect. Through heat insulation solar glass (HISG) encapsulation technology, this study improved the structure of a typical semitransparent PV module and explored the use of three types of high-reflectivity heat insulation films to form the HISG building-integrated photovoltaics (BIPV) systems. Subsequently, the authors analyzed the influence of HISG structures on the optical, thermal, and power generation performance of the original semitransparent PV module and the degree to which enhanced performance is possible. The experimental results indicated that the heat insulation performance and power generation of HISGs were both improved. Selecting an appropriate heat insulation film so that a larger amount of reflective solar radiation is absorbed by the back side of the HISG can yield greater enhancement of power generation. The numerical results conducted in this study also indicated that HISG BIPV system not only provides the passive energy needed for power loading in a building, but also decreases the energy consumption of the HVAC system in subtropical and temperate regions.
