Cable kev ntseeg siab thiab kev txheeb xyuas
Kev Taw Qhia
GRGT muaj qhov sib xyaw ua ke hauv cov xaim thiab cable kuaj thiab kev txheeb xyuas, muab kev kuaj ib zaug thiab txheeb xyuas cov kev pabcuam xaim thiab cable:
1. Ua raws cov qauv kev txheeb xyuas cov khoom tsim nyog tshaj plaws raws li hom cable thiab kev siv ib puag ncig, thiab tsim cov phiaj xwm kev txheeb xyuas kom zoo;
2. Raws li cov txiaj ntsig ntawm kev ntsuam xyuas kev ntseeg siab, kev ntsuam xyuas cable zoo yog ua los muab lub hauv paus rau cov neeg siv khoom xaiv;
3. Muab cov kev pabcuam kev ua haujlwm tsis zoo rau cov khoom siv cable uas tsis ua haujlwm ntawm qhov chaw kom paub meej qhov ua rau cable tsis ua haujlwm thiab pab cov neeg siv khoom txhim kho kom zoo.
Kev Pabcuam Scope
Cov kab hluav taws xob siab thiab tsis tshua muaj hluav taws xob thiab cov kab hluav taws xob rau cov tsheb ciav hlau thauj mus los;
Cov kab hluav taws xob siab thiab tsis tshua muaj hluav taws xob thiab cables rau roj thiab lub zog tshiab tsheb;
