Τα τελευταία χρονιά οι οργανισμοί αντιμετωπίζουν ένα κύμα τεράστιων αλλαγών στη δομή και οργάνωση τους Κάτω από αυτές τις συνθήκες προσπαθούν να αποκτήσουν ανταγωνιστικό πλεονέκτημα έναντι των αντίπαλων τους επενδύοντας σημαντικά ποσοστά των προϋπολογισμών τους σε πληροφοριακά συστήματα (ΠΣ) και ΤΠΕ γενικότερα ελπίζοντας οτι θα τους βοηθήσουν να βελτιώσουν την επίδοση (business performance) τους Η σχέση μεταξύ επενδύσεων σε ΤΠΕ και επιχειρηματικής επίδοσης αποτελεί ένα από τα σημαντικότερα πεδία έρευνας στο χώρο των πληροφοριακών συστημάτων Τα αποτελέσματα ωστόσο των διάφορων μελετών σχετικά με το θέμα αυτό παρουσιάζουν αντιφάσεις Η επικρατούσα άποψη σήμερα είναι οτι οι ΤΠΕ οδηγούν σε υψηλότερα επίπεδα οφελών για τις επιχειρήσεις Η σύγχρονη έρευνα εστιάζεται στους παράγοντες που συνδυάζονται με τις επενδύσεις ΤΠΕ για την αύξηση της απόδοσης και ονομάζονται «συμπληρωματικοί» (complementary factors) Οι βασικότερες προσεγγίσεις σχετικά με επενδύσεις σε συμπληρωματικούς παράγοντες αφορούν ...

During the last years (public and private) organizations face massive transformations in their structure and processes. Under those circumstances firms are making great efforts to acquire competitive advantage against their rivals by investing great proportions of their budgets in Information Systems (IS) and Information and Communication Technologies (ICT) in general hoping that those investments will help them improve their performance and achieve their aims. The relationship between ICT investments (ICT and IS will be regarded and mentioned throughout the text as identical) and business performance is one of the major research areas in the domain of IS and it becomes more interesting due to the fact that the results of various studies have been rather contradictory. Today it is a common belief that ICTs have a beneficial impact on business performance. The main approaches related to complementary factors regard business process change which is often expressed through two main approa ...
During the last years (public and private) organizations face massive transformations in their structure and processes. Under those circumstances firms are making great efforts to acquire competitive advantage against their rivals by investing great proportions of their budgets in Information Systems (IS) and Information and Communication Technologies (ICT) in general hoping that those investments will help them improve their performance and achieve their aims. The relationship between ICT investments (ICT and IS will be regarded and mentioned throughout the text as identical) and business performance is one of the major research areas in the domain of IS and it becomes more interesting due to the fact that the results of various studies have been rather contradictory. Today it is a common belief that ICTs have a beneficial impact on business performance. The main approaches related to complementary factors regard business process change which is often expressed through two main approaches Business Process Reengineering (BPR) and Total Quality Management (TQM). Additionally business performance is also influenced by top managements decisions regarding strategy as well as the various factors constituting the external business environment. The present PhD dissertation contributes to the existing literature by fulfilling the gaps that have been identified and mentioned in the literature or by confirming the findings of other studies. In particular it examines the relationship between ICT investments and business performance as well as the role of BPR TQM strategy external environment and national context on the above relationship. Finally it develops and empirically tests a method for evaluating particular IS based on the value they create for their users. For the above contributions 3 studies have been conducted with survey instruments. The development of the research hypotheses and the analysis of data have been realized through the Structural Equation Modeling (SEM) technique To sum up the findings of this study which are described in detail throughout the dissertation we have come up with the following conclusions: BPR and TQM play a crucial role in the relationship between ICT investments and business perofrmance The choice between deploying a BPR or TQM initiative is highly dependent on the particular strategy a firm follows Capital investments (ICT and non ICT) are accordant to the strategic choices of the firms The forces of the external environment do not directly impact business performance The amount of ICT investments as well as the extent of deploying BPR or TQM are directly dependent from the various forces of the external business environment The impact of ICT investments is influences by the national context The development of the VALUE FLOW MODEL APPROACH enables the evaluation of particular ISπερισσότερα
