About the Book

Il budget della NASA è diminuito e la tecnologia dei sistemi informativi (IS) comporta un investimento di milioni di dollari, quindi l'usabilità, il successo e il ritorno sull'investimento (ROI) hanno un impatto diretto sul budget della NASA. Due fattori determinanti per il successo dei sistemi informativi sono l'usabilità e l'intenzione di continuare a utilizzarli da parte degli utenti. In questo studio è stata utilizzata una metodologia quantitativa che utilizza la System Usability Scale (SUS) per misurare la soddisfazione che indica l'esistenza dell'usabilità e uno strumento post-accettazione che determina l'intenzione di continuare a utilizzare il sistema, indicando l'usabilità dei sistemi. Il sondaggio con scala di tipo Likert è stato somministrato a 114 partecipanti che lavorano su un contratto di integrazione del carico utile della NASA nelle aree di gestione, ingegneria e operazioni. La modellazione di equazioni strutturali ha testato le cinque ipotesi e determinato se esistesse una relazione tra utilità percepita, conferma, soddisfazione e intenzione di continuare. La teoria dell'aspettativa-conferma (ECT) e il modello di intenzione di continuare che utilizza la modellazione di equazioni strutturali (SEM) hanno misurato quantitativamente se esistesse una relazione tra utilità percepita, conferma, soddisfazione e intenzione di continuare.
