One of the key drivers for a firm's productivity growth is management. One lean management practice considered cost-effective is Kaizen. Originally from Japan, the Kaizen basic concept is continuous improvement with the involvement of the full workforce. Using a firm-level dataset from Brazil's innovation and manufacturing surveys, this paper evaluates quantitatively whether Kaizen has impacted the performance of domestic firms. Our initial results suggest a productivity premium on Kaizen adopters, yet when it materializes is not detectable in the short term. Moreover, the impact on innovation is observable after Kaizen implementation. Understanding these outcomes with a qualitative approach, our analysis highlights the importance of Kaizen on innovation, especially by improving worker's time at the production line as well as the long-term vision of Kaizen on productivity. In summary, Kaizen is not a magic wand that improves firms’ performance in a wide array of indicators yet it may boost innovation outcomes in the short term aiming to improve productivity in the long term if it is implemented carefully and persistently, as established by its basic principles.

This paper examines the issues in internal audit reliability. It specifically provides conceptual and practical insights into some of the consequential issues worth pondering about when assessing the reliability of the internal audit functions. Particularly, the paper identified and discussed four (4) of such issues namely: competency of internal auditors, level of management support/influence, independence and objectivity of internal auditors; and regulatory issues. The paper took a conceptual approach and draws its basis from the institutional and protection motivation theories. Based on literature and other documentary evidences, the paper took the position that the four identified factors would most likely influence the internal audit reliability. Among other policy implications, the paper, therefore, proposes a conceptual research framework to be empirically examined by future researchers.
