The Wisdom of Data-Driven Decision Making - DIKW:

Data-driven decision making

Data-driven decision helps organizations to:

• Make better decisions that are based on facts and evidence, rather than intuition or gut feeling.
• Identify and solve problems more effectively.
• Improve operational efficiency and productivity.
• Develop new products and services that meet the needs of their customers.
• Gain a competitive advantage in the marketplace.

The Process

The data-driven decision making process typically involves the following steps:

1. Identify the problem or opportunity. What are you trying to achieve or improve?
2. Collect relevant data. This could include data from internal sources (e.g., sales data, customer feedback, operational data) or external sources (e.g., market research data, social media data).
3. Clean and prepare the data. This involves removing errors and inconsistencies, and organizing the data in a way that can be easily analyzed.
4. Analyze the data. This involves using statistical methods and data visualization tools to identify patterns and trends in the data.
5. Interpret the results. What do the results of the data analysis tell you about the problem or opportunity you are trying to address?
6. Develop and implement solutions. Based on your interpretation of the results, develop and implement solutions to the problem or opportunity.
7. Monitor and evaluate the results. Track the results of your solutions to see if they are having the desired effect. If not, make adjustments as needed.

DIKW pyramid

The DIKW pyramid is a conceptual model that describes the relationship between data, information, knowledge, and wisdom.

• Data: Raw, unprocessed facts. (name, number, address
• Information: Data that has been processed and organized into a meaningful form. (this is their name, this is their number, this is their address)
• Knowledge: Information that has been interpreted and understood. (data model, schema)
• Wisdom: The ability to apply knowledge to solve problems and make good decisions. (AI, machine learning)

Data-driven decision making involves climbing the DIKW pyramid, from data to information to knowledge to wisdom. At each level, the data is transformed into a more valuable form.

Examples of data-driven decision making

Here are a few examples of how organizations use data-driven decision making:

• Amazon: Amazon uses data-driven decision making to recommend products to customers, optimize its supply chain, and develop new products and services.
• Netflix: Netflix uses data-driven decision making to recommend movies and TV shows to its users, produce new content, and decide how to allocate its resources.
• Coles: Coles uses data-driven decision making to optimize its pricing, inventory management, and store layout, mailing customers with deals.
• Target: Target uses data-driven decision making to personalize its marketing campaigns and target customers with relevant offers.
