You have been hired by a North American trucking firm to help reduce the number of deliveries that show up to customers later than their expected due date. The company is expecting you to develop a project that will use the company’s own data to solve this problem. Using the CRISP-
DM framework, answer the questions below.
Part 1
You spend several hours in a meeting with the company learning how their business works. You learn that the company receives its orders from a freight brokerage, which tells them where to pick up and where to drop off every load. Drivers are fined every time a load is delivered later than is expected.

Part 2
The data that you receive from the company makes no sense! There are many suspicious outliers. According to some of the entries, some loads were delivered 4000 hours early, others were 9200 hours late?! What does that even mean? You decide to go through the data and delete entries that seem suspicious.

You present to them your analysis. You have discovered that there are 3 distinct clusters of drivers working at the company. In one cluster are 1050 drivers who are old and come from American Midwestern states. In another cluster, there are 630 drivers who are young and come from Western states. In the final cluster are 129 drivers of all ages from Canada.
