2. Design Variables (Organizational Level) Centralization of decision making (4,5) Number of organizational levels involved in authorization (6) Number of nodes in the information-processing network (7) Design Variables (Organizational Memory) Development and use of computer-resident data bases (8) Development and use of computer-resident in-house expert systems (9) Performance Variables Effectiveness of environmental scanning (10) Quality and timeliness of organizational intelligence (11) Quality of decision (12) Speed of decision making (13,14) Design Variables (Subunit Level) Participation in decision making (1) Size and heterogeneity of decision units (2) Frequency and duration of meetings (3)

3. Effects at the organizational level Design Variables (Organizational Level) Centralization of decision making (4,5) Number of organizational levels involved in authorization (6) Number of nodes in the information-processing network (7)

4. Is the net effect of the use of computer assisted communication and decision-support technologies to increase centralization or to decrease it? Effects at the organizational level Centralization of decision making

5. Proposition 4: For a given organization, use of computer-assisted communication and decision-support technologies leads to a more uniform distribution, across organizational levels, of the probability that a particular organizational level will make a particular decision. Effects at the organizational level Centralization of decision making

6. Proposition 4a: For a highly centralized organization, use of computer-assisted communication and decision- support technologies leads to more decentralization. Example: Electronic bulletin boards enable lower- and mid- level managers to stay better informed about the organization’s overall situation. Effects at the organizational level Centralization of decision making

7. Proposition 4b: For a highly decentralized organization, use of computer-assisted communication and decision- support technologies leads to more centralization. Example: Technologies enable top managers to obtain local information more quickly and accurately. Effects at the organizational level Centralization of decision making

8. Proposition 5: For a population of organizations, broadened use of computer assisted communication and decision- support technologies leads to a greater variation across organizations in the levels at which a particular type of decision is made.  Enable organizations to allow decision making to occur across a greater range of hierarchical levels. Effects at the organizational level Centralization of decision making

9. Effects at the organizational level Number of organizational levels involved in authorization What is the likely effect of communication and decision- support technologies on the number of hierarchical levels involved in authorizing a particular decision?

10. Proposition 6: Use of computer-assisted communication or decision-support technologies reduces the number of organizational levels involved in authorizing proposed organizational actions.  Issue arises when user is faced with information overload and/or extreme differentiation.  May have to do with the general reductions in the size of the organizations when technology replaces workers. Effects at the organizational level Number of organizational levels involved in authorization

11. Effects at the organizational level Number of nodes in the information-processing network Do technologies actually decrease the number of nodes in the organization’s information-processing network?

12. Proposition 7: Use of computer-assisted information processing and communication technologies leads to fewer intermediate human nodes within the organizational information-processing network. Proposition 7a: Use of computer-assisted information processing and communication technologies reduces the number of organizational levels involved in processing messages. Effects at the organizational level Number of nodes in the information-processing network

13. Effects on organizational memory Design Variables (Organizational Memory) Development and use of computer-resident data bases (8) Development and use of computer-resident in-house expert systems (9)

14. What are the effects of computer- assisted communication and decision-support technologies on the nature and quality of organizational memory? Effects on organizational memory  Memory search refers to the “scanning of the organization’s existing memory, human or paper.”

15. Proposition 8: Availability of computer-based activity and transaction- monitoring technologies leads to more frequent development and use of computer-resident data bases as components of organizational memories. Proposition 9: Availability of more robust and user-friendly procedures for constructing expert systems leads to more frequent development and use of in-house expert systems as components of organizational memories. Effects on organizational memory

16. Effects on organizational intelligence and decision making Performance Variables Effectiveness of environmental scanning (10) Quality and timeliness of organizational intelligence (11) Quality of decision (12) Speed of decision making (13,14)

17. What is the effect of advanced information technologies on these impediments? What is the effect on information acquisition overall? Effects on organizational intelligence and decision making Environmental scanning and organizational intelligence

18. Proposition 10: Use of computer-assisted information processing and communication technologies leads to more rapid and more accurate identification of problems and opportunities. Effects on organizational intelligence and decision making Environmental scanning and organizational intelligence

19. Proposition 11: Use of computer-assisted information storage and acquisition technologies leads to organizational intelligence that is more accurate, comprehensive, timely, and available.  Assumption : information is accurate, comprehensive, timely, and available.  How inclined are users to employ accessible sources. Effects on organizational intelligence and decision making Environmental scanning and organizational intelligence

20. Proposition 12: Use of computer-assisted communication and decision- support technologies leads to higher quality decisions. Effects on organizational intelligence and decision making Decision making and decision authorization

21. Proposition 13: Use of computer-assisted communication and decision-support technologies reduces the time required to authorize proposed organizational actions.  Reducing the number of levels involved in authorizing an action will reduce the number of times the proposal must be handled. Effects on organizational intelligence and decision making Decision making and decision authorization

22. Proposition 14: Use of computer-assisted communication and decision-support technologies reduces the time required to make decisions. Effects on organizational intelligence and decision making Decision making and decision authorization
