Intro to MIS DATA INFORMATION AND COMMUNICATIONS
DATA
Definition: Processing data into information is essential for a Management Information System (MIS).
Differences between Data and Information:
Data: Collections of facts and figures (e.g., hours worked, invoice values).
Information: Processed and communicated data that is useful to the recipient.
Sources of Data:
External Sources: Readily usable form.
Internal Sources: Must be captured by measuring and recording systems.
Selection of Data: Organizations must be selective due to the limitless nature of available data.
INFORMATION
Definition: Data processed to be useful for planning, controlling, and decision-making.
Information Characteristics:
Source: Internal, external, primary, secondary.
Nature: Quantitative, qualitative, formal, informal.
Level: Strategic, tactical, operational.
Time: Historical, present, future.
Frequency: Continuous, hourly, monthly.
Use: Planning, control, decision-making.
Form: Written, visual.
Occurrence: Planned intervals, occasional, on-demand.
Type: Detailed, aggregate.
Functions of Information:
Reduces uncertainty by providing relevant information.
Aids in monitoring and control of performance.
Serves as a communication channel for developments and forecasts.
Acts as a memory supplement for historical performance.
Simplifies complex problems for better understanding.
INFORMATION QUALITY
Good Information Characteristics:
Content Dimension:
Accuracy: Free from errors.
Relevance: Related to specific recipient needs.
Completeness: All necessary information provided.
Scope: Internal or external focus.
Performance: Measurement of activities and progress.
Time Dimension:
Timeliness: Available when needed.
Currency: Up-to-date information.
Frequency: Provided as often as needed.
Time Period: Information about past, present, and future.
Form Dimension:
Clarity: Easy to understand format.
Detail: Available in detail or summary.
Order: Arranged in a logical sequence.
Presentation: Various forms (narrative, numeric, graphics, etc.).
Media: Printed documents, video displays, etc.
VALUE OF INFORMATION
Information value = Change in behavior caused by information - Cost of producing the information.
Relevance: Information must be relevant and understood by the user to hold value.
UNDERSTANDABILITY
Transforming Data into Information: IT makes data usable and valuable.
Factors Affecting Understandability:
User preferences for different forms of information.
Remembered knowledge influencing comprehension.
Environmental factors (time, trust, etc.).
Language used to convey information - can be code or natural languages.
COMMUNICATION
Essence of MIS: Interchange of facts, thoughts, and opinions to transmit information.
Forms of Communication:
Face-to-face, written, visual, oral, electronic.
Communication Process:
Encoding: How the message is expressed.
Channel: Means of carrying information.
Noise: Factors causing distortion of the message.
Decoding: Understanding derived from the message.
Importance of ensuring messages are received and understood.
BARRIERS TO COMMUNICATION
Common Barriers:
Differing backgrounds (age, education, etc.).
Language issues (jargon, terminology).
Volume of the message (too much/little information).
Distortion or withholding of information by bureaucracy.
Poor presentation adapting to recipient needs.
FACTORS IN CHOOSING COMMUNICATION METHODS
Consider urgency, security, complexity of the message, recipients, need for records, distance, and costs.
