Levels of the Organization
Lina, SCCG5013-6
Levels of the Organization Explained
Executive LevelStrategic planning and responses to strategic issues occur here. Executive decisions are usually unstructured and are made using information consolidated internal and external information

Basic Systems Model
Lina, SCCG5013-11
System Type: Transaction Processing Systems
Lina, SCCG5013-12
System Description: Transaction Processing
SystemsTPSs are a special class of information systems designed to process
business events and transactions
Architecture Components• Source Documents – these contain the event or transaction
information to be processed by system• Data Entry Methods
• Manual – a person entering a source document by hand• Semiautomated – using a capture device to enter the source
document (e.g. a barcode scanner)• Fully Automated – no human intervention, one computer talks
or feeds another computer (e.g. automatic orders from inventory systems)
• Processing – transactions can be either: • Online – processed individually in real-time • Batch – grouped and processed together at a later time

System Description: Management Information
SystemsMISs are used by managerial employees to support recurring decision
making in managing a function or the entire business
Supported Activities• Scheduled Reporting - the system produces automatically based
on a predetermined schedule. Some include:•Key Indicator – High-level summaries to monitor performance (e.g. Monthly Sales Report)
• Exception – Highlights situations where data is out of normal range (e.g. Monthly Late Shipments)
• Drill Down – Provides lower level detail aggregated in a summary report (printed only if needed)
• Ad Hoc Reporting – unscheduled reports that are usually custom built to answer a specific question (e.g. sales data by person report to identify issues)

System Type: Executive Information System
(EIS)
Lina, SCCG5013-19
System Description: Executive Information Systems
EISs, also called Executive Support Systems (ESS), are special purpose information systems to support executive decision-making
System DetailsThese systems use graphical user interfaces to display consolidated information and can deliver both:
• Soft Data - textual news stories or non-analytical data• Hard Data – facts, numbers, calculations, etc.
Supported ActivitiesThe activities supported by these kinds of systems include:
• Executive Decision Making• Long-range Strategic Planning• Monitoring of Internal and External Events• Crisis Management• Staffing and Labor Relations

Systems That Span Organizational Boundaries
Lina, SCCG5013-23
System Description: Decision Support Systems
Decision Support SystemsSpecial-purpose information systems designed to support managerial-level employees in organizational decision making
System Details These systems use computational software to construct models for analysis (most common MS Excel) to solve semi-structured problems (e.g. sales or resource forecasts)
Supported Activities: “What-if” analysis – changing one or more variables in the model to observe the resulting effect (e.g. what is the payment if the interest rate increases 1%)

System Description: Expert Systems
Expert SystemsSpecial-purpose systems used by operational level employees to make decisions usually made by more experienced employees or an expert in the field
System Details These systems use inference engines that match facts and rules, sequence questions for the user, draw a conclusion, and present the user a recommendation
Supported Activities:These systems support many activities including:
• Medical Diagnosis• Machine Configuration• Financial Planning• Software Application Assistance (help wizards)

System Description: Office Automation Systems
Office Automation SystemsA collection of software and hardware products that increase productivity within the office setting
Supported ActivitiesThe activities supported by these kinds of systems include:
• Scheduling Resources• Document Preparation
Examples: software (word processing and desktop publishing); hardware (printers) Examples: electronic calendars with resource management (equipment, facilities, etc.)
• CommunicatingExamples: e-mail, voice mail, videoconferencing and groupware

System Description: Collaboration Technologies
VideoconferencingSoftware and hardware the that allow parties to meet electronically with both picture and voice Supported Activities
• Stand-alone Videoconferencing • High quality, typically very expensive systems using
dedicated microphones, cameras and hardware. • Can support meetings between several people and locations
simultaneously • Desktop Videoconferencing
• Lower quality, relatively inexpensive systems using a PC, small camera, and a microphone or telephone for voice communication
• Allows two individuals to communicate from a desktop
Lina, SCCG5013-35
System Description: Collaborative Technologies
(Groupware)GroupwareSoftware that enables people to work together more effectively
Supported Activities
These systems come in two types:• Asynchronous Groupware – Systems that do not require
users to be on the system working at the same time including: e-mail, newsgroups, workflow automation, group calendars, and collaborative writing tools
• Synchronous Groupware – Systems that allow and support simultaneous group interactions including shared whiteboards, electronic meeting support systems, video communication systems

Remember !!!
“ In a market crowded with vendors pushing
the latest hot new technologies, we must
understand that information
technology is about solving our business problems, not having
the latest, most advanced devices and software packages.”
