Two strong determinants of successful information systems are usability and the user¿s continuance intention. A quantitative methodology design, utilizing the System Usability Scale (SUS) was used in this study to measure satisfaction indicating the existence of usability and a post acceptance tool which determines continuance intention indicating systems¿ usability. The Likert-type scale survey was given to 114 participants working on a NASA payload integration contract in the management, engineering, and operations areas. Structural equation modeling tested the five hypotheses and determined if there was a relationship between perceived usefulness, confirmation, satisfaction, and continuance intention. The expectation¿confirmation theory (ECT) and the continuance intention model using structural equation modeling (SEM) quantitatively measured if there was a relationship between perceived usefulness, confirmation, satisfaction, and continuance intention.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659677274\"\u003e\u003ch3\u003eIn the International Space Station Integration Processes\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783659677274","offer_id":39467444142173,"sku":"9783659677274","price":33.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/e0ca7fbf-bdec-4f5f-936e-5e9895bb8b72.jpg?v=1773469508","url":"https:\/\/shop.autorenwelt.de\/products\/evaluating-the-usability-of-information-systems-von-nelda-nagy","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
