How would you measure your service performance?

Feedback is a good way, select random customers and give them a discount or a free product and survey them. 

A lot of people measure performance in a focused setting, but performance should be broad for example just because your employee did not accomplish his work or task does not mean he failed it weather or not he helped your team all together accomplish the goal you have set forth for them.

For any service quality measurement whether in Admin or procurement or Human resources or Hotel, or Airlines or maintenance and so on, we can  set up criteria how the service quality is to be measured in terms quality, quantity, timeliness, usefulness, satisfaction level of users/receivers of services. Then, we can make an online survey or hire a third party to make an assessment.  After that  we need to analyse the response and  see how we are performing. 

A lot of  branded hotels make their online survey through a set of questions send to the Hotel occupants through email or a survey sheet placed placed in the room

Thanks

If you mean services side of administrative function not (executive) e.g. (Administrative jobs, Customer Services, Client Services, Legal services, ..)

So it be measured by achieving assigned tasks , i.e. ( complete the archiving for achieved project, Hired selected candidate and complete the papers work, answer all customers questions and solve their issues,...)

For me it comes down to Customer Satisfaction. This could be internal customers or external customers.

there are several ways to measure this - including repeat business as well as simply asking them (in one of the appropriate manners like a survey or offer)

Thank you for invitation. I am agree with colleagues answer,also looking forward new opinion.

Feedback and survey are helpful to measure any service. 

WE CAN MEASURE OUR SERVICE PERFORMANCE BY CONSIDERING THE NO OF CUSTOMERS

Thank you for the invitation.

I agree with Mr. Fazlur Rahman.
