Knowledge Management – Data, Information, Knowledge & Analytics
DATA – Fundamental Concepts
Definition
Raw facts, figures, symbols, or characters collected without context or interpretation.
Can be quantitative (numerical) or qualitative (descriptive/categorical).
Considered meaningless until processed; therefore often called "unprocessed facts" or "inputs."
Key characteristics
Objective, context-free, and unorganized.
Susceptible to overload when massive quantities are gathered without structure.
Examples from transcript
Strings such as 12012012 (a date hidden in an unrecognized format).
Numbers 100 or 5\% presented without explanation.
Environmental readings: gage height, precipitation volume.
Transformation cue
Data requires contextualization and processing to evolve into information.
INFORMATION – Processed & Contextualized Data
Definition
Data that has been organized, interpreted, structured, or presented to provide meaning to a user.
Described as “processed facts” or “contextualized data.”
Properties
Purpose-specific, has meaning, and supports decision-making.
Still objective yet now framed within a relevant context.
Subject to information overload when excessive but organized facts are delivered without filtration.
Illustrative examples
Trend analysis of daily temperatures revealing seasonal patterns.
Website visitor counts month-over-month showing growth or decline.
Warehouse inventory plotted across time to flag supply-chain bottlenecks.
annual interest applied to a principal returning after one year.
KNOWLEDGE – Actionable Understanding
Definition
Accumulated insights, experience, and skills that enable interpretation of information and facilitate decisions.
Unique to each individual; shaped by past encounters and stored expertise.
Key traits
Subjective and value-laden; draws on authority and capacity to act.
Non-quantifiable; no concept of “knowledge overload.”
Connects multiple pieces of information, answering “how” questions.
Flow feedback
Knowledge may expose gaps or redundancies in collected data, prompting new data-collection or processing methods.
Practical examples (water case study)
Converting stream-gage heights to streamflow ➜ knowledge triggers withdrawal restrictions if below .
Identifying long-term precipitation growth ➜ prioritize flood-plain mapping investments.
Mapping lead contamination to customer data ➜ issue alerts for health compliance.
DIKW PYRAMID – Hierarchical Progression
Levels (bottom ➜ top)
Data: Raw signals.
Information: Answers who, what, when, where.
Knowledge: Answers how (application and relations).
Wisdom: Answers why / what is best (guiding action).
Insights
Each ascent adds value by enriching meaning.
Data & information focus on past descriptions; knowledge & wisdom guide present actions and future goals.
DATA TYPES
1. Qualitative (Categorical)
Generally non-numeric; describe attributes.
Two sub-types:
Nominal: Pure labels, no inherent order (e.g., hair color, nationality).
Ordinal: Ordered categories, differences unknown (e.g., satisfaction levels, socio-economic status, “123 = Beginner < Intermediate < Advanced”).
2. Quantitative (Numerical)
Represent counts or measurements.
Two sub-types:
Discrete: Countable, indivisible values (e.g., number of children, coin-flip heads).
Continuous: Measurable, infinitely divisible (e.g., weight, price, height, annual income).
DATA ANALYSIS & ANALYTICS
Definition of Data Analysis
Working with data to extract useful information enabling informed decisions.
Involves cleaning, transformation, modeling, and communication.
Four Analytics Categories (Complexity ↑)
Type | Core Question | Typical Output/Tools |
|---|---|---|
Descriptive | “What happened?” | KPIs, financial statements, head-count reports |
Diagnostic | “Why did it happen?” | Root-cause analysis, Pareto charts, fishbone diagrams |
Predictive | “What will happen?” | Forecasts, statistical models, scenario projections |
Prescriptive | “How can we make it happen?” | Optimization algorithms, actionable recommendations |
Visual ratios (from slide): – of analytics effort often remains descriptive/diagnostic.
Descriptive Statistics Toolkit
Measures of frequency (counts, percentages).
Central tendency: Mean, Median, Mode.
Dispersion: Range, Standard Deviation, Variance, Quantile ranks.
Diagnostic Methods (Deep-Dive)
Root-cause analysis.
Correlation & regression.
Fishbone (Ishikawa) diagrams.
Pareto (80/20) analysis.
Predictive Analytics
Uses historical & current data to model future outcomes.
Example: Cash-flow forecasts for the next month.
Prescriptive Analytics
Combines diagnostic + predictive insights to suggest optimal actions.
Evaluates multiple simulated outcomes to pick best path.
FIVE-STEP DATA ANALYSIS PROCESS
Define the question(s)
Ex: “What is the yearly sales trend?” “Are we gaining corporate customers?”
Collect data
First-party, Second-party, Third-party sources.
Clean the data
Remove errors/duplicates/outliers, fix structure, fill gaps.
Analyze the data
Employ descriptive → diagnostic → predictive → prescriptive techniques.
Share/Visualize results
Dashboards, reports, interactive visuals; ensure clarity for stakeholders.
KNOWLEDGE MANAGEMENT (KM) & DATA-DRIVEN CULTURE
Goals of KM platforms
Centralize data ➜ convert to accessible, actionable information.
Increase data accuracy & reliability.
Embed informed decision-making across all organizational levels.
Benefits
Streamlined processes, heightened agility, engaged employees.
Fosters innovation & improves customer engagement.
Distinction
Technology supplies tools; knowledge management supplies strategy—organizing, interpreting, applying data.
CULTIVATING A DATA-DRIVEN ORGANIZATION
Implement KM systems that:
Collect & transform data into coherent, timely information.
Provide universal access to insights.
Support continuous feedback loops (data ⇆ information ⇆ knowledge).
Outcomes
Enhanced operational efficiency.
Evidence-based policy & strategy development.
Competitive advantage through superior knowledge and wisdom.
CONCEPTUAL PROGRESSION SUMMARY (DATA ➜ WISDOM)
Data: Symbols without context.
Information: Contextualized answers to basic questions.
Knowledge: Integrated how-to understanding and capacity to act.
Wisdom: Judicious application answering why and determining best actions.
