建立健全的工作制度体系。任何工作的有效落实都离不开制度体系的制约与保证，电力设备的检修与维护工作也是如此。首先应结合电力企业相关工作的实际落实情况，完善或制定全面性的规章制度，并且严格要求其有效落实。制度中要突出工作具体内容、要求以及工作周期等。电力企业应结合实际编制设备检修作业指导书，有机融合相关制度标准及厂家设备安装维护手册的各项标准认真组织执行。建立工作质量追溯系统。为了进一步保证相关工作各环节的高质量完成，电力企业应针对设备检修与维护工作部分建立质量追溯系统，将不同工作内容进行具体划分，将工作职责落实到个人，这样可以提高员工对设备运行情况的全面掌握程度，同时还可以对员工的工作起到监督作用，并激发员工的工作热情，端正工作态度。
