Organizational Learning （OL） and Organizational Innovation （OI）： The Case of Information and Communication Technology （ICT） Industry in Malaysia

The progression through which a person acquires ,;kills, understanding, and opinions regarding a particular organization or company is called organizational learning （OL）. In this study, the connection between organizational innovation （OI） and OL within the inf3rmation and communication technology （ICT） industry in Malaysia is surveyed. These relationships are examined, because various previous inquiries have shown that an imperative precursor to firm performance is OL. Two hundred and seventy-eight surveys were completed by small and medium organizations across Malaysia. The connections existing between the causes of OL and the causes of OI were ascertained by using structural equation modeling （SEM）. Amongst the Malaysian small- and medium-sized enterprises （SMEs） that participated in fire study, OI and OL are considerably linked.     

Measuring the Impact of Information Technology （IT） on Supply Chain Management （SCM） Through Indicators： An Exploratory Study

Enterprises are looking to adapt to this scenario focusing on performance, seeking to improve the level of service and reduce costs in an attempt to differentiate and increase the perceived value of their customers. A strong partner to achieve these goals is the information technology （IT）. IT has an important role in the performance of companies, providing a flow of information that makes the supply chain more robust and resilient, without compromising efficiency. To achieve the objective of this research, a survey of the literature on the four models was studied and then a field research with professionals was conducted in the areas of IT and supply chain management （SCM） of various companies of Sao Paulo. To collect the data needed for analysis, we used the exploratory research of a qualitative nature. Thus, we conclude that the use of IT impacts supply chain in five surveyed areas as planning, manufacturing, suppliers, customers, and delivery but does not impact the return area.

Introducing Stakeholder-Based Frameworks for Post-merger Integration （PMI） Success

The importance of stakeholder relationship management for successful integration in post-merger management is not doubted. The establishment of a new powerful trend in investments produces strategic shifts in strategic management. Shareholder wealth maximization way of thinking is changing to stakeholder wealth maximization where a company＇s value management system is based not only on economic profit maximization, but also on environmental, social, and governance （ESG） maximization. There is especially a high need for a management system that can be used by mergers and acquisitions （M＆A） practitioners during integration process. There is a critical need for metrics which can trace the interests of all stakeholders, because to achieve success in integration, it is no longer acceptable for management to focus solely on the needs of one or two stakeholder groups. In this article, the authors have introduced two frameworks： sun cube and stakeholder relationship matrix. These tools can be useful in mergers and acquisitions （M＆A） process for conducting a stakeholder analysis.     

Integration of Individualized Management Systems （MSs） as an Aggregating Factor of Sustainable Value for Organizations An Overview Through a Review of the Literature

Nowadays, there exist various standards for individual management systems （MSs）, at least, one for each stakeholder. New ones will be published. An integrated management system （IMS） aims to integrate some or all components of the business into one coherent and efficient MS. Maximizing integration is more and more a strategic priority in that it constitutes an opportunity to eliminate and/or reduce potential factors of destruction of value for the organizations and also to be more competitive and consequently promote its sustainable success. A preliminary investigation was conducted on a Portuguese industrial company which, over the years, has been adopting gradually, in whole or in part, individualized management system standards （MSSs）. A research, through a questionnaire, was performed with the objective to develop, in a real business environment, an adequate and efficient IMS-QES （quality, environment, and safety） model and to potentiate for the future a generic IMS model to integrate other MSSs. The strategy and research methods have taken into consideration the case study. It was obtained a set of relevant conclusions resulting from the statistical analyses of the responses to the survey. Globally, the investigation results, by themselves, justified and prioritized the conception of a model of development of the IMS-QES and consequent definition and validation of a structure of an IMS-QES model, to be implemented at the small- and medium-sized enterprise （SME） where the investigation was conducted.
