Questions

4. Decision Support Systems (DSS)
Interactive computer-based systems which help decision-makers utilise data and models to solve unstructured problems (Scott-Morton).
Uses the power of computers to solve all types of problems.

5. Group Decision Support Systems (GDSS)
Type of DSS used by groups of people.
An interactive computer-based system that facilitates the solution of unstructured problems by a set of decision-makers working together as a group (Turban).

6. Executive Information Systems (EIS/ESS)
Flexible tools that provide top managers and executives with direct access to useful and relevant information.
Uses external and internal information.
Normally graphical representation of information.

7. Data Mining
Process of discovering new correlations, patterns and trends in an organisation's data
Uses statistical and mathematical techniques to uncover hidden trends

8. Traditional meetings Only ONE person talks!
Hear, understand and remember everything?
Time is wasted
Members are absent
Result:
Limit number of people
dissatisfaction of the final decision

9. Traditional meetings Research on this subject still continues…
Through research conducted at the University of Arizona a product called Ventana Group systems was developed
Ventana Group systems is a GDSS application

10. . access to leading-edge technology founded in 1989
Partners with industry leaders
access to leading-edge technology

11. Teams can interact Whenever - Wherever they need to work together

12. resources to allow interaction
Folders
Agenda
Survey
resources to allow interaction
people, whiteboard, handouts and opinion maker reports
Resources to improve productivity
brief case, personal log and find

13. GroupSystems tools Categoriser Electronic Brainstorming Group Outliner
Topic Commenter
Vote
Alternative Analysis
Activity Modeller

14. Each participant can be entering ideas or commenting on existing ideas at the same time as other participants. (You can also import a list of ideas from a text file or another GroupSystems tool such as Electronic Brainstorming.)

15. Categoriser

21. DDN Rapid growth Service oriented
led to becoming the largest information technology company is S.A.
Business processes supported by out of date applications and existed in isolation
No regard for overall impact on company or customers
Service oriented
redesign their business processes from a systems theory point of view, i.e. recognise that each department’s work influences the entire company
Business processes - implemented in ad hoc fashion to cope with growth

22. DDN Interviews, observations, and analysis of existing documentation
Deadlines!!!!!

23. Application of the Activity Modeller
Team leaders identified the main existing business processes
e.g. plan technical implementation
Activities of Business process
best qualified people describe how each process operated
26 Activity modeller workshops
to expand on and connect activities
to streamline the ”As-Is” models into “To-be” models
identify redundant activities and activities to automate

24. Results: Fast and Efficient
Many people worked on a process in parallel
Information was available immediately and in electronic format
Developed new processes
facilitated early process buy-in
Time for each workshop was shorter therefore focus and momentum were maintained

25. EIS/DSS Demo Large number of EIS/DSS/OLAP tools
Includes products from companies such as
SAP
Oracle
IBM
Pilot Software
And Cognos products
Powerplay
Scenario

26. Cognos Powerplay SE 5.21 Used by 1000s of organisations world-wide
PowerPlay summarises and presents corporate data the way users understand their business.
Rated by Infoworld as World’s Number 1 OLAP tool.

27. Powerplay’s Characteristics
Drill down to the lowest level of detail
Slice and dice
Highlight exceptions
Converts currencies automatically
Rank and compare results
Analyse trends over time
Visualise data graphically

29. London Underground 2. 5 million customers per day
2, 500 ticketing devices
Implemented Cognos powerplay to cope with large volumes of data.
Powerplay provides staff with the ability to analyses patterns, spot trends and anticipate problems.
Resulted in better decisions and improved ticket selling services to its customers.

30. Conclusion Illustrated some of the theory in the paper
Given practical cases of where decision making applications have been used
Understanding of these applications and their benefits
Changes in business and developments in technology have led to the development of applications that will sustain competitive advantage

31. Conclusion By making data available in strategic format
Representative of the real world
to identify problems and help generate quicker, efficient decisions that give optimal solutions
