Kegunaan indeks upaya proses bagi mentaksir prestasi proses telah mencetus minat dan juga kontroversi pacta akhir Iapan puluhan dan awal sembilan puluhan. Ada pihak yang mengkhuatiri keberkesanannya memandangkan indeks-indeks ini bukan bersifat ketentuan, tetapi sebaliknya bersifat rawak dan dengan demikian tafsirannya bergantung kepada bentuk taburan pendasar. Ada yang skeptis tentang bagaimana satu nombor dapat meringkaskan kelakuan taburan proses dan berjaya menggambarkan sepenuhnya prestasi proses. The use of process capability indices to assess process performance has stirred interest as well as controversy in the late 80's and early 90's. There are those who doubt their effectiveness since these indices are not deterministic but rather random in nature and hence their interpretation depends on the shape of the underlying distribution. Others are skeptical as to how a single number can effectively summarise the behaviour of a process distribution and fully capture the performance of the process.
