## 4 Conclusions
The strongest correlation, given the use of IoT solutions by managers, was found between the risk of cyberattacks on personal data (PS1) and the sense of contribution to professional success (EM1). The exogenous variable FC showed a positive and insignificant impact (0.960 \(<\) 1.96) on Extrinsic Motivation. The second negative impact of the construct was displayed between the latent variables Perceived Privacy (PP) and Extrinsic Motivation (EM). The influence of PE, SI and PS factors has been highlighted by other previous studies [127; 128]. In the last stage of the construct model, the null hypotheses H\({}_{12}\) and H\({}_{13}\) were confirmed. Thus, the endogenous variable Extrinsic Motivation (EM) has a positive and strong impact on Intrinsic Motivation (IM) (\(\beta\) = 0.344, \(p\) = 0.000). Given the use of IoT solutions by managers, two strong correlations were found, the first (0.718) between recognition of personal achievements (EM2) and easy mastery of work tasks (IM2) and the second (0.663) between the feeling of contribution to my success (EM1) and that of involvement, pleasure and satisfaction (IM1). The endogenous Intrinsic Motivation (IM) factor has a significant and strong impact on the variable Behavioral Intention to Use IoT solutions (BI) (\(\beta\) = 0.542, \(p\) = 5.879 \(>\) 1.96). Two other strong correlations are identified between the prediction of using IoT solutions in the future (BI3) and (0.666) the feeling of involvement, pleasure and satisfaction (IM1) and (0.703) the ability to easily master any task (IM2). Regarding the impact of Extrinsic Motivation (EM) on Behavioral Intention to Use IoT solutions (BI), the alternative hypothesis was accepted (\(\beta\) = 0.180, \(p\) = 1.511 \(<\) 1.96), this impact being positive but insignificant. The influence exerted by the three exogenous variables Extrinsic Motivation (EM), Intrinsic Motivation (IM) and Behavioral Intention to Use (BI) have been the subject of numerous previous studies [19; 94]. The results of this study have important and very useful implications for managers in Romania and also for those in other countries, regardless of the sectors of activity where they work, experience or location, highlighting the factors that should be considered and their impact. on the intrinsic and extrinsic motivation in substantiating the decisions and strategies regarding the implementation and use of IoT solutions within one's own activity, in order to improve future personal and business performance. A significant implication is the stimulation of intrinsic motivation due to the intention to use IoT solutions in the future. It is highlighted as a source of energy that pushes to action, an engine of the entire activity of managers, both personally and professionally, which aims to develop clear and concrete objectives such as: increasing the ability to monitor, control and use IoT solutions, identify new challenges and interact with the IoT ecosystem, identify options and opportunities for developingdesired activities, reduce the number of decisions and achieve more efficient results, get involved in managing and designing your own IoT solutions, participate in specialized courses, closeness and involvement in new relationships with colleagues and business partners and much more. Another significant implication that contributes to the support of extrinsic motivation is the need to recognize that the acceptance or intention to use IoT solutions in the next period, by managers, should be managed with objectives such as: increasing personal productivity, faster work tasks, facilitating the exchange of ideas in the IoT partner community, providing the necessary support for the use of IoT solutions; the use of strong passwords to increase the security of personal information and reduce the risks of information manipulation, protection through the use of encryption technologies and ensuring better confidentiality and security of personal and business information.
