Trend analysis has improved troubleshooting and program testing for accurate, reliable outputs
The features I appreciate most in GE Proficy Smart Factory MES are the ability to create trends when I troubleshoot during my daily work. I can also edit the program in GE Proficy Smart Factory MES, and before I download it to the PLC, I can test it first to ensure my program is working correctly. GE Proficy Smart Factory MES has been very useful in my daily work because it is user-friendly. I can also go online and change the IP address easily, which is simpler compared to other solutions. Troubleshooting with GE Proficy Smart Factory MES is easier than other options.

Team collaboration has improved and project tracking is clearer but downtime still causes disruption
I think there are some parts of Lark that have not been translated, and sometimes there is a glitch where the product still uses Chinese words. Lark occasionally experiences downtime, and during those times, we usually use WhatsApp for communication and coordination, which can be frustrating. Regarding Lark's AI capabilities, I believe they are good in terms of governance and security. I think there is still room for improvement regarding the accuracy and reliability of Lark's AI output.
