The drawback is that most of internal systems are third-party systems that have been difficult to integrate for a long time. Additionally, each department has its own priority requirements, and the IT department has limited decision-making authority. There is also a lack of effective project management processes, and the company still relies on traditional, outdated methods for project and personnel management. Furthermore, the bonus/profit share system is susceptible to significant fluctuations due to the impact of global supply chain demands.
