Abstract: 

The term usability refers to a special index for success of an operating system. This study aimed to determine the reliability and validity of the Software Usability Measurements Inventory (SUMI) questionnaire as one of the valid and common questionnaires about usability evaluation. The back translation method was used to translate the questionnaire from English to Persian back to English.
Moreover, repeatability or test-retest reliability was practically used to determine the reliability of the SUMI questionnaire. The target population of the study consisted of all personnel of the governmental organizations in the city of Tehran, Iran, from whom 29 persons participated in the study to fill out the SUMI questionnaire. The Persian version of this questionnaire is available at designer’s data bases under the title of IRSUMI_31. The obtained coefficients of reliability were 0.838 in testing step and 0.722 in retesting step, respectively. The coefficients represented a satisfactory proof for the content validity and reliability of the questionnaire. The Persian version of SUMI questionnaire is applicable for all domestic made software as a valid and applicable factor.
