Information for Management
A. Attributes of quality information Z-1992 Table 3.3 p 86; Z-1998 2.1
B. Internal vs external information Internal- information for TPS, MRS, DSS, OIS External- information for DSS, EIS
Organizational advantage is gained from external data

Management Reporting Systems (MRS)
Objective: provide lower & middle management operational control information monthly/weekly performance reports attendance reports sales reports inventory reports
18
19
Management Reporting Systems (MRS)
A. Characteristics of MRS Designed by MIS, large & complex, multiple users &
DB's Support highly structured queries, stable DO NOT necessarily support decision making; provide information for structure decisions Oriented on past & present Have limited analytical capabilities; summaries Report on internal organization operations
20
Management Reporting Systems (MRS)
B. Reporting by MRS
Reports produced from main DBMS and or local DB's Scheduled periodic reports Exception reports Demand (Ad hoc) reports: limited queries or
views of Data
21
Decision Support Systems (DSS)
Support decision making process (unstructured & semi-structured decisions); facilitate a dialogue between user and system; the DB is generally an extract of the main DB Developed by user and MIS Use application packages (123, etc) Generally very flexible (can be modified) Support the decision making process
22
Decision Support Systems (DSS)
Project future states of the "world" Have analytical capabilities Use internal & external data Graphics capabilities

Executive Information Systems
Provide support for top executives and their aids. Unstructured and semi-structured decision making. Provide easy access to key information pertaining to the
company and environment User "seductive" interfaces; Users' time is a premium Provide access to internal & external DB's What if capabilities abound Tailorable systems; cognitive styles

Expert Systems
Knowledge based about a specific domain Use heuristic in the process New systems use neural nets Expert systems are knowledge based systems
that imitate a reasoning process (heuristic) to suggest a solution within a specific domain

Informational Support of Management
Control information: status or progress information warning information comfort information FEEDBACK information
31
Levels of Planning & Control
A. Operations Planning & Control Lower level management Highly structured Repetitive information Examples: Scheduling, inventory movement,
aging reports, cash flow reports, etc. Involves examining the progress of planned
events and dealing with contingencies if necessary
32
Levels of Planning & Control
B. Tactical Planning & Control Middle management Semi-structured and structured The acquisition and implementation of resources to fit the
strategic plan The financial plan for a new MIS system; The plan to match the labor requirements of an MRP II
run; The resources required for the introduction of a new
product Use DSS and GSS systems
33
Levels of Planning & Control
C. Long-term Strategic Planning & Control Top Management Unstructured, semi-structured Examples:
A diversification strategy downsizing Long-term market strategy Outsourcing
EIS systems Internal and external data

Functional Departmentation & MIS
A. Organizational Structure Independent units: Strategic Business Units
(SBU's) Each has their own business objectives Each SBU can be subdivided into functional
departments or divisions Figure Z-1992 3.10 p103 Figure Z-1992 3.11 p104

B. Information support of a functional area: Marketing Marketing objective: Create a market and sell 4 P's Marketing MIS Hierarchy
Operational: weekly scheduling of sales force and promotions order processing and customer follow-up
38
Functional Departmentation & MIS
Tactical: Sales force and product forecasting Promotional planning & budgeting Comparisons with industry standards Competitive performance analysis MEASUREMENT
Strategic: What is our Market? How will we satisfy the customers needs? What does the customer want?

The Role of MIS
A. Introduction Information technology is partly responsible for the
PARADIGM shift (A change, a new model,) from support to contributing to an organizations profitability.
From efficient data processing shops to understanding the goals and objectives of an
Organization to participating directly in the decision making and
strategy formulation
41
The Role of MIS
The role of the MIS Executive: Systems Planning Data Center Management & Operations Management of Remote Equipment Identification of Opportunities for New Systems Systems Analysis, Design, and Construction of New
Systems Distributed Systems: The migration of equipment to
user areas and control (selection, purchase, and ownership). Standards sometimes set by IS department.
42
The Role of MIS Knowledge Users: Users take on increased responsibility. Identify
applications, and conduct systems analysis and design. Better Applications: More specific, user friendly, functional, lower
price, readily available, and self training. Results: less need for programmers, IS head count and budget decrease as a result.
Outsourcing: Other, external organizations taking over the management and control of the data centers. Results: cost reductions head count reductions budget reductions.
43
The Role of MISSprague, 1993, 2.1, p37
44
The Role of MIS
B. The CIO's Responsibilities 1. Understand the business: products, markets &
customers 2. Establish credibility of the systems department:
responsiveness to needs and requests 3. Increase the technological maturity of the organization:
"Make it easier to take advantage of computer and telecommunications applications,” Spend money, keep up with technology and applications
45
The Role of MIS
4. Create a vision and sell it: Create a goal for the use of IT within the Organization and sell the goal to others (The Marketing of IT)
5. Implement a systems architecture that will support the vision and the company in the future. This is perhaps the most difficult responsibility (the Tech, and the Paradigm keep changing).
46
The Role of MIS
C. Understand the Business Environmental Scanning: Find out what is happening in
the market place Concentrate on the lines of the business Sponsor weekly briefings Attend industry meetings with line executives Read industry publications Hold informal listening sessions Become a partner with the line manager
47
The Role of MIS
1. Environmental Scanning External
industry background Pertinent government regulations History & framework
Internal business goal and objectives major policies and practices The inputs, outputs and resources of the firm
48
The Role of MIS
2. Concentrate on Lines of Business Treat inputs as a request from a customer and outputs as
an order going to a customer. Example: GM sells cars, parts and financing. Each is a
different line of the business, and each would required different systems.
support current operations use system to influence future ways of working
49
The Role of MIS
3. Sponsor Weekly meetings IS departments need to understand the business and the
operating departments need to understand the systems side.
Meetings (Weekly, monthly, quarterly, as needed) can help inform and communicate to all members of the organization.
This also help change the culture to one that is open and accessible to change.
50
The Role of MIS
4. Attend meetings with line managers: PC EXPO
5. Read industry publications: PC Week, CIO, etc
6. Hold informal listening sessions: Manage by walking around
7. Become a partner with the line manager
51
The Role of MIS
D. Establish Systems Department Credibility Typically may MIS organizations have not delivered the systems on time built the "best" systems provided timely maintenance or enhancements controlled costs
52
The Role of MIS
IS/IT must become responsive to the needs of the organization. How? By providing systems on time the "best" system provide for maintenance and enhancements controlling costs
53
The Role of MIS
E. Increase Technological MaturityIn a technologically mature organization both the organization and the employees are comfortable using and managing the technology. Ease of use use in intended ways have a good attitude to it have control over it
54
The Role of MIS
To get comfortable: IS can train and educate provide flexible systems provide "Usable" systems
55
The Role of MIS
F. Create a Vision of the Future Paradigm shift from reactive to proactive. Examples:
order an elevator in one day design an build a house from a store reprice funds in an hour or less
A vision is a statement of how someone believes the future will be or how he/she wants the future to be. 1. explore the present 2. look at tends and make projections
56
The Role of MIS:Effective visions
57
The Role of MIS H. Why develop a vision?
1. To set a direction. providing internal stability for a firm in an unstable environment.
2. To help inspire people to take initiative Creating a Vision
1. Explore the Present look at prior experiences: ask questions fiddle around: experiment get participation: Communication clarify the vision over time: feedback Listen
58
The Role of MIS
2. Scouting the future study trends look for shifts in trends How?
look everywhere convergent thinking (consensus, reduction in
equivocality divergent thinking ability to map the future imagination and visioning
59
The Role of MIS
3. Ideas for the Future- Dooley Group Conference Decline in growth of cities Holograms to replace travel Small is better than big Personalized products Portable and personal 2-way communication Small powerful batteries Manufacturing in outer space A power shift from a manufacturing base to a
KNOWLEDGE base Deterrence of the aging process.
60
The Role of MIS
I. Implement an Information System Architecture The IT infrastructure of an organization) Hardware, software, communications. Issues:
IT should focus on simplifying organizations IT should flatten hierarchies IT should shift emphasis on competition to
simplification Link IT with business strategy
61
The Role of MIS
J. Six Lessons about selling Selling is necessary to advance ideas Selling is how things get done in any enterprise 1. Understand your market place
reduce uncertainty about the market place identify the need fill the need with a product
2. Listening is a Potent form of selling 3. Make your buyer successful
living up to your commitments and making your customers successful
62
The Role of MIS
4. Keep your buyer informed: Customer care 5. Bring in a spokesman if Necessary 6. Personal relationships are the key
63
The Evolving Systems Function
C. Where are Systems Departments Headed? 1. One view from CSC (Computer Science
Company) an outsource vendor
outsourcing is here IS manages become contracts administers outsourcing vendor will use "their" platforms IS people are either outplaced or absorbed
64
The Evolving Systems Function
Strategic alignment lower level empowerment Teams developing the strategy (Groups)
The questions that must be asked is: What is need to support the business? How will the business be supported?
65
The Evolving Systems Function
2. Another point of view (A panel discussion) The user has/will the IS power The Guild system An infrastructure for both central and de-central
control Usability, and satisfaction Leadership and direction guidance and coordination
66
The Evolving Systems Function
D. Building Relationships with Line Departments 1. Redefining Roles and Skills
development support business support technical services business services
67
The Evolving Systems Function
2. Managing Risks IS projects are becoming more complex, widespread,
and Expensive IS personnel are beings distributed- central systems,
division systems and functional systems. Thus, top management must assume responsibility They are more conservative, cautious, less
knowledgeable
68
3.13 The Evolving Systems Function
3. Building Relationships Because of costs- build external relationships with
vendors, consultants, academics Because of complexity- build internal relationships
with senior management Because of competition- build relationships with users-
usability and satisfaction.

Conclusion
THE TRANSFORMATION OF IS
"we used to do it to them:" the systems groups (EDP) required end users to obey strict rules for getting changes made to the systems, submitting job requests, etc. Mainframes, transmittals, batch processing, punch
cards, data entry clerks EFFICIENCY
70
Conclusion
"Next, we did it for them:" systems groups moved to service. Mainframes, large mini's with custom systems built by IS
without user involvement EFFECTIVENESS, Efficiency
"Now, we do it with them:" the partnership Mini's, PC, Windows, application packages USABILITY, Effectiveness, Efficiency
71
Conclusion
"We are moving toward teach them how to do it themselves:" UNIX environments, work stations, PC, LANs,
application packages SATISFACTION, USABILITY, Effectiveness,
efficiency
