Once you have chosen the best EMS for your project, you need to properly implement and evaluate it. To start, you should plan and design the EMS by defining its scope, objectives, and specifications. You should also identify the roles, responsibilities, and resources involved, as well as select the hardware, software, and communication systems. Additionally, a detailed schedule, budget, and risk management plan should be developed. Next, you should install and commission the EMS components and systems. You should test and calibrate them, configure and program the settings and parameters, and verify and validate their functionality and performance. After that, you should operate and maintain the EMS by operating it according to the schedule and mode. You should also monitor and analyze its data and outputs, adjust and optimize its settings and operations, maintain its components and systems, update its software and hardware, etc. Finally, you should evaluate the EMS results and impacts by comparing its performance with the baseline and targets. You can then identify gaps or issues that need to be addressed with corrective or preventive actions. It's important to review and improve the EMS plan as well.
