Week 4 Assignment – Case Study: Transforming Data Into Information

Overview

The Woodmill Company makes windows and door trim products. The first step in the process is to rip dimension (2 × 8,2 × 10, etc.) lumber  into narrower pieces. Currently, the company uses a manual process in  which an experienced operator quickly looks at a board and determines  what rip widths to use. The decision is based on the knots and defects  in the wood.

A company in Oregon has developed an optical scanner that can be  used to determine the rip widths. The scanner is programmed to recognize  defects and to determine rip widths that will optimize the value of the  board. A test run of 100 boards was put through the scanner and the rip  widths were identified. However, the boards were not actually ripped. A  lumber grader determined the resulting values for each of the 100  boards, assuming that the rips determined by the scanner had been made.  Next, the same 100 boards were manually ripped using the normal process.  The grader then determined the value for each board after the manual  rip process was completed. The resulting data, in the file, Woodmill Data, consists of manual rip values and scanner rip values for each of the 100 boards.

Instructions

You are a process manager at the Woodmill Company tasked  with determining if an optical scanner would be  beneficial. Write a 4–5 page report to your supervisor (including a  cover page and a Source List page) in which you:

1. Summarize the Woodmill Company’s problem of ripping dimension lumber into narrower pieces.
2. Develop a frequency distribution for the board values for the scanner and the manual process.
3. Generate appropriate descriptive statistics for both manual and scanner values.
4. Analyze the frequency distribution and descriptive statistics for  both manual and scanner processes. Use Excel to create your charts.
5. Determine which process generates more values (manual or scanner).
6. Evaluate which process has less relative variability, using frequency distribution and descriptive statistics.
7. Recommend whether the optical scanner is the best option for the company.
8. Use two sources to support your writing. Choose sources that are  credible, relevant, and appropriate. Cite each source listed on your  source page at least one time within your assignment. For help with  research, writing, and citation, access the library or review library guides
