Making Data-Driven Decisions

1. The Decision-Making Framework

Step 1: Define the Question

• What specific decision needs to be made?

• What are the potential options?

• What would success look like?

• What are the risks of each option?

Step 2: Gather Relevant Data

• What data do we need to answer the question?

• Do we have access to this data?

• How reliable and recent is the data?

• What additional context is needed?

Step 3: Analyze and Interpret

• What patterns or trends do we see?

• Are there any surprising findings?

• What are the limitations of our analysis?

• How confident are we in our conclusions?

Step 4: Make the Decision

• What does the data recommend?

• Are there any non-data factors to consider?

• What are the next steps?

• How will we measure success?

Step 5: Monitor and Iterate

• Track the results of your decision

• Compare actual outcomes to predictions

• Learn from successes and failures

• Adjust your approach based on new data

2. Common Decision Scenarios
