Evaluation of the use of business process reengineering (BPR) for improving business-IT alignment by utilizing the intelligent decision support system (IDSS)

The present study aimed to evaluate the use of business process reengineering (BPR) to improve the business-IT alignment in knowledge-based businesses in Tehran by MATLAB programming software. The research issues included the ambiguity and fatigue of decision-makers and managers of knowledge-based businesses in Tehran due to the combination of different methods of evaluating the use of BPR to improve the business-IT alignment. Using the intelligent system, the status of "improving the alignment of IT with knowledge-based businesses of Tehran" can be examined numerically and more accurately: From the perspective of ideal importance, if the state of "IT service business strategy process reengineering (X1)" is good, i.e. 0.813, and "IT service business design process reengineering (X2)" is good, i.e. 0.824, and "IT service business transfer process reengineering (X3)" is good, i.e. 0.819, and "IT service business operation process reengineering (X4)", i.e. 0.812, and "IT service business continuous improvement process reengineering (X5)" is good, i.e. 0.815, then the state of "improving the alignment of IT with Tehran knowledge-based businesses" is at the "excellent (fifth level)" level, i.e. 0.952. According to the membership functions of linguistic variables by experts, the value of 4.76 within a 5-value range in the range defined for the "excellent" linguistic variable, i.e. the state of improving the alignment of IT with knowledge-based businesses in Tehran was obtained equal to 0.952 with a programming code [0.813; 0.824; 0.819; 0.812; 0.815].
