14. Six Sigma Metrics (量化指標)◆ Summarizing Data
■Mean describes the central tendency of a data set
■Standard Deviation describes the spread of a data set
◆ Example:
▽The weights, in Ibs., of a random sample of bricks of raw material from:
▽Supplier 1:3.45, 4.30, 3.55, 3.96, 3.58
▽ Supplier 2:3.74, 3.73, 3.78, 3.69, 3.92您會選擇那一家供應商?Which supplier do you select
15. Six Sigma Metrics◆ Customer Requirements
■ Target:4.00
■ Tolerance:+ /-1.0 3.0 4.0 5.0Supplier 1:$1.00/partWhich supplier
would you select ? 3.0 4.0 5.0Supplier 2:$1.25/part
28. 長期與短期即使是良好的流程在長時期也會出現小的變異
傳統上, 這個長期變異定義爲相對短期能力1.5 s的修正
一個流程短期性能是6 s 即被認爲是長期性能是4.5 s 的流程時間预期结果多數流程數據在短期與長期之間
29. 流程偏移時間預期结果
30. 流程漂移時間預期结果
31. 檢驗是無共識的作業`Twas brillig, and the slithy toves Did gyre and gimble in the wabe:All mimsy were the borogoves, And the mome raths outgrabe.
"Beware the Jabberwock, my son! The jaws that bite, the claws that catch!Beware the Jubjub bird, and shun The frumious Bandersnatch!"
He took his vorpal sword in hand: Long time the manxome foe he sought -So rested he by the Tumtum tree, And stood awhile in thought.
And, as in uffish thought he stood, The Jabberwock, with eyes of flame,Came whiffling through the tulgey wood, And burbled as it came! One, two! One, two! And through and through The vorpal blade went snicker-snack!He left it dead, and with its head He went galumphing back.
"And, has thou slain the Jabberwock? Come to my arms, my beamish boy!O frabjous day! Callooh! Callay!' He chortled in his joy.`Twas brillig, and the slithy toves Did gyre and gimble in the wabe;All mimsy were the borogoves, And the mome raths outgrabe.
