Engineering homework help. Do the first three of the following.– even a little more for linking the three together (e.g. either do charting and check-sheets to investigate problems brainstormed in the Fishbone, or using a Fishbone to brainstorm root causes of problems that come up in control or Pareto charts…) In ALL cases start with a short but concise written explanation of the process/problem of interest, any relevant context (i.e. was it at an internship? Relevant to some organizational or volunteer work you do? etc.), and the data collection methods used.
1. Use a fishbone chart to brainstorm root causes of a problem of relevance to you. This could be a real industrial problem (e.g. something you saw on an internship or previous job) or a less serious but still interesting personal organization problem (e.g. why do I always do homework the last night before it is due?). Create an Ishikawa (fishbone) diagram brainstorming possible root causes for the problem. Start with the standard major branches unless they seem very inappropriate for your problem, in which case come up with new ones. Put as many possible causes as you and your associates can think of on the diagram, irrespective of your initial feeling about how likely they are. There is a good example on Slide 24 of the Process Control lecture; use the methods in slide 25 to sort through the causes if you want to investigate them further in parts 2 and/or 3 below.
2. Collect data on a process of interest to you, and plot on a control chart. Note this needs to be something that involves QUANTITATIVE data on THE SAME process as it varies over time. Determine the “two sigma” process control limits of your process (the bounds into which 95% or so of your data falls, or the Mean+/-2x(Standard Deviation) of the data). Remark on any anomalous or “outlier” points observed. Does this chart teach you anything interesting about the process? Now plot the SAME data on a Histogram chart; do you find any additional insights into the process? Slides 17-20 of the Process Control lecture and Slides 12-16 of the Quality lecture would help here.
3. Collect data on MULTIPLE problems that can be quantified using the SAME units (e.g. M&M colors, incidents, different reasons time spent/wasted, etc.). Collect the data using a check sheet, and once it is collected present it is using a Pareto chart, preferably including a cumulative line. Comment on what the chart tells you – is there a single problem that dominates? What set of problems need to be addressed to tackle (say) 80% of the total? Slide 12 of the Quality Tools lecture has a good example of a check sheet; the totals in the right-hand column could be used to create a Pareto chart using the method in slides 17-22. Hand in via Canvas. Everyone should do their own work and hand in a unique set of charts, but it is OK to discuss the problems with classmates (acknowledge any collaborations!). Grading will include completeness (don’t forget written intros), correct use of tools (keep Histogram and Pareto straight!), quantity of data/ideas (12ish ideas, 20 data points + for most problems), and creativity of approach.
