In a series of linked processes and associated feedback loops the product or service flows ________ and the information flows ________.
In a resolution III fractional factorial experimental design, main effects are confounded with:
A project activity not on the critical path has required 20% longer than the time originally allocated. The project team should:
A team’s goal is to improve information flow in a payroll function. They make thirty-three Post-It® notes, each listing an issue for further investigation. After some discussion, they group them into four categories: mandated record keeping, privacy concerns, insurance concerns and transfer concerns.
This grouping process is best described by which approach to problem solving?
The management team in the above problem assigns each goal a numerical value designating its importance. The “bulls eyes,” circles and triangles are replaced by the values 3, 2 and 1 respectively. Entries are made in each box by multiplying the 3, 2 or 1 by the goal value.
The importance of each activity is calculated by adding the entries in its row.
A team wants a technique for doing an initial study of a process that not every team member is familiar with. They should use:
SCENARIO
A Six Sigma team is measuring the moisture content of corn starch as it leaves the conveyer belt of a dryer. They collect one sample four cups of starch at times indicated in the chart at fixed locations labeled A, B, C, and D across the end of the belt. See the diagram below.
After some more work on the dryer, additional data are collected which when plotted looks like this:
Which type of variation dominates?
The average weight of castings produced at the Nebraska foundry is 3.7 lbs. A new supplier from Kansas has submitted a batch of castings known to have normally distributed weights. A random sample of 10 has an average weight of 3.6 lbs. and standard deviation 0.06 lbs. Do these data indicate that the Kansas foundry produce lighter castings on average?
Find the value of (1) in the ANOVA table. Assume:
An automatic gaging system is to be installed in a process. The gage will insert data values into a data base from which machine adjustments will be made automatically. A critical factor in specifying the equipment is:
