Information systems Wikipedia An information system aims to support operations, management and decision-making. An information system is the information and communication technology (ICT) that an organization uses, and the way in which people interact with this technology to support business processes.

Ελλάδα ΕΘΝΙΚΗ ΨΗΦΙΑΚΗ ΣΤΡΑΤΗΓΙΚΗ 2016 2021 Ριζική αναθεώρηση του τρόπου παροχής Ψηφιακών Υπηρεσιών του Δημοσίου Πληθώρα ερευνών που έχουν διεξαχθεί σε παγκόσμιο επίπεδο, καταδεικνύουν ότι τα έργα πληροφορικής εμφανίζουν γενικά χαμηλά ποσοστά επιτυχίας. Σύμφωνα με τη μελέτη του Standish Group, μόνο 3 στα 10 έργα ολοκληρώνονται με επιτυχία (on time, on project, on scope), με το μέγεθος του προϋπολογισμού να επηρεάζ ει αντιστρόφως ανάλογα το ποσοστό επιτυχίας (2% στα πολύ μεγάλα, 62% στα μικρά) και τη μεθοδολογία υλοποίησης να επηρεάζει δραματικά το αποτέλεσμα (39% με ευέλικτη υλοποίηση και 11% με συμβατική μεθοδολογία). 5
Ελλάδα ΕΘΝΙΚΗ ΨΗΦΙΑΚΗ ΣΤΡΑΤΗΓΙΚΗ 2016 2021 Στη χώρα μας πολλά έργα πληροφορικής του Δημοσίου ήταν «Ολοκληρωμένα Πληροφοριακά Συστήματα» και ότι η μεθοδολογία υλοποίησης που εφαρμόζεται μέχρι σήμερα, είναι η συμβατική γραμμική μεθοδολογία (waterfall), η οποία δεν αντιμετωπίζει διαφορετικά τα έργα ΤΠΕ από τα υπόλοιπα έργα του Δημοσίου. Αν στα προηγούμενα προστεθεί και η επίδραση των παθογενειών του ελληνικού δημοσίου, όπως: η απουσία κεντρικού σχεδιασμού για έργα και δράσεις ΤΠΕ με αποτέλεσμα να υπάρχουν επαναλήψεις, επικαλύψεις αλλά και λύσεις τύπου «σιλό», οι χρονοβόρες διαδικασίες και δύσκαμπτες διαδικασίες του συστήματος παραγωγής έργων και προμηθειών που δεν είναι συμβατές με τις απαιτήσεις του κύκλου ζωής των έργων ΤΠΕ, και πολλα άλλα 6
