Has this ever happened to you?

I had some operational improvements and business ideas, but when I spoke with the systems department, they said it would be difficult to handle right now.

Since different vendors are used for each application and system infrastructure, the workload and losses in managing communication have gotten serious.

Lead time for system development is too long due to the constraints of hardware modification and upgrading. Costs are also too high.

Want to be proactive in using advanced technologies, but can’t due to the lack of in-house knowledge and people promoting it.
