How the ERP system works in our production and ads posting process? When a production contract made between sales and customer, operation team would be noticed to do the further work. In the peek time, since the high volume of productions and posting jobs, it’s hard to finish the job on time, and more importantly, hard to trace the current status of a customer job. If six sales want to get the updated information of their orders’ production and posting ads, they have to communicate with the operation team personally, and cause unnecessary workload and pressure for the operation team. Sometimes the operation team cannot give you the exact time when ads are fully produced and when ads are fully posted on metro. An ideal ERP system would be implemented historical data and related models to calculate and offer those key information, which is more reliable that man made work. And sales can trace those numbers any time in the system. In another case, when an in-train ad is posted, normally the operation team cannot give the sales the exact time when the train is out for operation (So that customer can check the ads or we can take the pictures for ads). An ideal ERP system would be linked to the metro operation system, so they would monitor every train’s activity: if the train is being repaired; how many times i would run today, and how many passengers on that train. It would help marketing team to precisely calculate target coverage of the ads in that train, to make a reliable after-ads report to the customer.
