Each chart in this GB560 Unit 9 control plan, an individuals chart at 27.3 hours, a p-chart for refund errors and an aging count, has an owner and a reaction rule. Searches like "gb 560 unit 9 assignment example", "gb560 unit 9 sample" and "gb560 unit 9 example" land here.
What a finished GB560 Unit 9 control plan looks like
About five pages with three charts and a response table. The individuals chart plots twenty daily medians from the pilot, averaging 27.3 hours, with an average moving range of 2.95, an upper limit of 35.2 hours and a lower limit of 19.5; the moving range chart's upper limit is 9.65. The p-chart tracks the share of refunds corrected after posting, averaging 0.41 percent, with daily upper limits near 1.54 percent at 290 refunds and a weekly limit near 0.91 percent at 1,450. A third measure counts exception-lane items older than 48 hours each morning, with a fixed ceiling of five. The response table states what each signal triggers: one point beyond a limit, eight in a row on one side of the center, or the ceiling passed.
How a GB560 Unit 9 example is structured
What must stay true once the pilot team leaves is named first, and one measure is attached to each item. Chart choice is explained in a paragraph per measure: an individuals chart for daily medians because each day produces one value, a p-chart for errors because the counts are proportions with varying daily volume. Limits are calculated in an appendix with the constants shown, so any supervisor can recompute them. A section on rare events explains why the daily error chart can detect only large jumps and adds the weekly limit. The response table lists each signal, the owner who acts, the time allowed and the first check to make. Recalculation rules state when limits will be reset, after twenty days at full volume. The returns supervisor takes the plan over from the project lead on a named date, and a backup is listed.
One measure per promise
Refund speed, refund accuracy and exception aging each map to a Unit 2 requirement, and nothing is charted that no receiver cares about.
Why these charts
One daily value suits an individuals chart; proportions from varying volumes suit a p-chart, and the plan explains each choice in a paragraph.
Limits anyone can redo
Constants of 2.66 and 3.267 and the p-chart formula appear with the pilot's figures, so the supervisor can recompute limits without the project team.
Rare errors, weekly view
At 0.41 percent, daily error limits catch only large jumps, so a weekly limit near 0.91 percent is added for slower drift.
Signals that mean work
Each signal names who responds, within how many hours, and the first thing checked, starting with the scan-link error log.
Limits reset on schedule
After twenty days at full volume the limits are recalculated, and the plan says what change would justify resetting them sooner.
Where marks go in GB560 Unit 9
A promise that the process will be monitored, with no chart, no owner and no stated response, controls nothing, and rubrics for this unit treat it that way. Control limits confused with targets, a 30-hour goal drawn as if it were a limit, misrepresent what the chart can show. Chart types chosen without regard to the data, such as an individuals chart for proportions with changing volumes, produce limits that mean little. Limits computed from too few points, or from data gathered before the change, describe the old process. Responses written as review the chart leave the person on shift without an instruction. Handover dates and backup owners carry weight with graders, since a plan owned by a project lead who is leaving controls nothing. Each measure is also expected to trace back to a stated requirement.

Expect a chart chosen for each measure, limits calculated with the constants shown, and a response table naming who acts on each signal. Initial custom samples carry no charge and usually arrive within 24-48h.
GB560 Unit 9 questions, answered
What is the difference between a control limit and a target?
A control limit describes what the process currently does, calculated from its own variation. A target describes what someone wants it to do. A process can sit comfortably within its limits and still miss a target, or beat the target while showing a signal of instability. The sample draws limits from pilot data and lists targets separately in the requirements table.
Why use an individuals chart rather than an X-bar chart?
Because the returns center produces one daily median, not subgroups of several measurements taken together. An X-bar chart needs rational subgroups; with one value per day, the individuals and moving range pair is the usual choice. If your process yields several readings per period, such as samples per shift, an X-bar and R chart may fit better.
How often should limits be recalculated?
When the process has changed deliberately, or after enough new data has accumulated under stable conditions. The sample recalculates after twenty days at full volume, because the pilot covered one product family only. Recalculating after every signal is a common error, since it absorbs the very shifts the chart exists to reveal and leaves the supervisor blind to them.
