Once the KPI has been set, we will start improving business operations by going through the PDCA while monitoring the value. With ServAir, daily data such as work contents, failure causes, and countermeasures related to after-sales service work can be registered in business flow. As a result, data is naturally accumulated and since KPIs can be displayed in real-time, there is no need to perform tasks such as listing and tabulation again, thus, the workload can be minimized.
