Computer Hardware Purchase Standard

Hi, Can anyone of you share with me if you have got a standard purchase plan for computer hardware ?

Probably I should look into the combination of 2 things ...the level or position of the employee, as well as the the role or job functions.

Example : Traveller should get a light laptop ; technical person should get an advance machine wherelse management should only get a standard spec machine coz they mostly do planning and managing ....

Please share your thought and any of your available standard ?!

Thanks in advance
