A KPI is a calculated value that indicates the effectiveness with which a company performs its key purposes. Businesses use performance indicators at different levels to assess their ability to achieve their goals. But I didn’t use this tool. I read a blog about this before days. so that’s why I’m asking these questions. I need to know about this topic. Is this the best tool? or Do you have any better tools better than this? If you have any best tools better than this tool please suggest to me.
