Pareto Analysis:
There is a rule of thumb called the Pareto Rule. It states that 80% of a problem is due to 20% of the causes. If we focus on this critical 20%, we can make big improvements. The Pareto chart is a type of chart that helps us to organize our data. The item (or source) that occurs most frequently is shown first, then the next most frequent one, and so on. The purpose of this type of analysis is to focus our attention on the the items that occur most frequently, so that we get the most value for our efforts. When a quality problem exists in an organization, management may collect data about sources of the problem and then create a Pareto chart as one of the tools of Total Quality Management (TQM). Here is an example which shows that bathroom cleanliness is responsible for the majority of dissatisfied customers at a restaurant. Implementing a procedure to solve this problem is most important thing for management to address to improve customer satisfaction . Please review this brief article on Pareto Analysis. which contains an additional business example. "Reasons for dissatisfied customers as a restaurant" pareto chart is a bar chart with 4 bars: "bathroom cleanliness" has a count of 70, "long wait for table" has a count of 33, "poor service" has a count of 12, and "high prices" has a count of 3.
Exception Reporting:
Exception Reporting is method of control that is often used in businesses. It uses computerized systems to monitoring a process using a predefined standard of success. Only those cases which are outside the standard or "exceptions" are brought to the manager's attention. In this way, the manager does not need to monitor everything; he or she can devote attention to the "exceptions" that need intervention or correction.

Exception reports can be used in all functional areas and all types of businesses! Here are a few examples:
- Fast food restaurants need to serve their drive-through customers rapidly. Let's imagine that the standard set at a particular restaurant is to deliver the order in less than 3 minutes. When a customer finishes ordering, a timer begins that is visible to the restaurant manager. If the timer exceeds 3 minutes (an exception), a buzzer sounds and the manager can step in to help expedite the order.
- The UPS delivery scenario described in your textbook is also an example of an exception reporting system. If drivers are not completing their route duties according to predetermined time standards, then it shows on an exception report for management. As a result a manager will ride along in the van to coach that driver to help him reach higher productivity levels.
- For inventory control in a store, there may be a standard set in the point-of-sale (cash register) system that if a particular product sells to a point where there are less than 5 units left in inventory, an email goes to purchasing to request a refill order.
- Here is a sample exception report for a manager who is trying to keep overtime costs under control. It looks like on 09/14, overtime exceeds an allowable limit:
QUESTIONS:
I'd like you to create a pareto chart on a problem in your life. Please select one of the ideas listed below which make use of data that has already been collected for you. If you want to study another problem, you need an automated data collection mechanism (such as a phone app or fitness tracking device). Please email me the problem you wish to study and what your data collection mechanism is by Tuesday for approval. You must collect objective data (not your opinions). Otherwise stick to one of these topics and do not make up data..
- Why I always feel broke (analyze expenditures on a credit card or bank statement).
- Sources of text messages on my phone (or email messages in my inbox).
- Reasons our place is messy (clean up the room and categorize items found).
