what happens in the Act phase?
Now it’s time to act on your data. You will take everything you have learned from your data analysis and put it to use.
These six steps can help you to break the data analysis process into smaller, manageable parts, which is called structured thinking. This process involves four basic activities
Recognizing the current problem or situation
Organizing available information
Revealing gaps and opportunities
Identifying your options

By analyzing the wait times at shipping hubs, analysts can determine the appropriate schedule changes to increase the number of on-time deliveries.
what is an example of Finding patterns
Minimizing downtime caused by machine failure is an example of a problem requiring analysts to find patterns in data. For example, by analyzing maintenance data, they might discover that most failures happen if regular maintenance is delayed by more than a 15-day window
Which problem type involves assigning information to different groups or clusters based on common features?
