## 2 Methodology
### Coding Method  
Data were coded by using Microsoft Excel spreadsheet, Yoshikoder, and Mendeley. Two coder process is utilized to code the selected papers. First, all the determinants were identified that might influence the adoption decision regarding the BIS. In addition, different forms of expression might be utilized by different authors to identify the specific determinant and given determinant might be mentioned in any part of the paper. The frequent repetition of many determinants was observed, it showed the adoption and acceptance behavior of BIS in organizations. Hence some determinants are bunched under the one determinant such as cost determinant is representing the technology cost, organizational cost and affordability. Although, the determinants frequency has been counted because of their sustained utilization with the same name without any specific judgment but sometimes similar terms have been utilized differently by some researchers. Content analysis by humans helps to overcome the limitations of the software analysis tool in finding relevant determinants. The reliability is also improved to combine both methods of analysis. The intensity of frequency was focused on analyzing the papers. The Yoshikoder is used to calculate the frequency accurately by analyzing specific keyword in-context documents. This computer-assisted software is used for content analysis with basic text mining function [20; 35]. However, the human coding process cannot be replaced by computer software. Therefore, basic results interpreted manually to attain the relevant precise results for the contextualized documents. This effort would help to diminish the software limitations in digging the related determinants. The software analysis can improve the reliability of the results.  
The usage frequency of each determinant was calculated, if one determinant was repeated multiple times in the selected studies, its frequency was measured in order to the number of times it stated in the papers. The determinants were explored and categorized into four dimensions in accordance with the proposed theoretical framework. The dimensions are individual, technological, organizational, and environmental. Two coding techniques have minimized the biases and maintained the high reliability [20].The one coder has identified manually all the determinants and highlighted the texts that have all the influential determinants for BIS adoption and acceptance at an organizational level and individual level. The other coder examined the notes manually, which were highlighted by the first coder. All identified determinants were grouped together after mutual consensus by all authors. All the obtained results were recorded in the Microsoft Excel spreadsheet. Data coding has been done of 84 identified studies relevant to the study objective. Many researchers have prescribed various methods for data extraction from the literature [31; 32; 33; 34]. At this stage, a form was designed to store the extracted information from the selected articles to make sure the completeness of the data retrieval process [24]. The form has several headings, such as study ID, study type, study year, study context, study objective, country, research methodology, key factors/determinants, theory/framework/model, and study sector. The final agreement coefficient in this process was 85%.
