Plan from the supplied facts
The synthetic planning period contains standard kind S=900 cases, exception X=80 and exception Y=20. A proposed release includes S only. Volume coverage is 900/1000=90%, while kind coverage is one of three. Counts describe this supplied period only.
| Kind | Period cases | In first release |
|---|---|---|
| S | 900 | Yes |
| X | 80 | No |
| Y | 20 | No |
Work through the choice
The denominator must match the claim. Ninety percent of case volume does not mean ninety percent of kinds, and does not validate outcomes on the included cases.
If X is added, what are the two coverage measures?
Show the worked answer
Volume is (900+80)/1000=98%; kinds are two of three. Y’s 20 cases remain excluded.
Material to use in your plan
Keep counts by kind and an inclusion flag. Report included volume/total volume and included kinds/total kinds as separate fractions with the same period reference.
