The manufacture of high-quality cars at comparatively low-cost has gradually become the mainstream. Our study designs a set of integrated time-driven-activity-based costing (TDABC) of performance-oriented systems using the bottleneck-breaking concept of theory of constraints (TOC). We use it to provide timely and relevant information on operation resources and cost management, which is an urgent issue. Through applications of TOC to TDABC, we further integrate cost concepts into the information system of the enterprise to achieve the following objects: First, the company can concentrate its limited resources on the main problem of bottleneck operations to effectively solve the inconsistency between individual departments and overall objects of the company. Second, in business process management, the company leads all operation processes to follow three major performance indicators. Third, the production-planning units are assisted in applying the specifications and definition of product to the manufacturing cost analysis of new product development. Fourth, in the delivery time, the production and management units are assisted in giving priority to the bottleneck operations when facing rush orders. Finally, in process improvement, improving bottleneck operations fast is the key for overall profits of the corporation.

This study examines two areas of auditing: namely, the identification of those factors that are associated with audit risk, business risk, and personal risk; and secondly how culture affects risk assessment. A factor analysis and a logistic regression are used to analyze questionnaire data collected from Singapore and Taiwan. The results show that three factors (the effectiveness of control activities, reporting bias of management and reliability of management) are strongly associated with the auditors risk assessment. This result replicates findings of previous research, indicating the importance of understand the clients control environment in the assessment of the likelihood of material misstatements. In addition, this study also hypothesized that differences in the cultural values of Chinese auditors are likely to result in differences in the risks assessed. The results show that auditors place more emphasis on their firms risk rather than their personal risk. However, compared to auditors in Taiwan, auditors in Singapore seem to be more concerned with risks at the individual level than at the group level. It implies the impact of Western Anglo-Saxon ideas on individuals from a Chinese background.
