Adapun penjelasan dari tabel nilai performansi aktual KPI diatas yaitu, kolom pertama yaitu nomor index dari masing-masing KPI, Kolom kedua menunjukkan
nama KPI, kolom ketiga menunjukkan kategori dari KPI, kolom keempat dan kelima menunjukkan rentang minimum dan maksimun nilai performansi KPI, kolom keenam
menunjukkan pencapaian aktual KPI untuk periode Agustus sampai dengan Desember 2009, kolom ketujuh menunjukkan satuan nilai performansi KPI.
4.4. Scoring System Dengan Normalisasi Masing-Masing KPI
Scoring System berfungsi untuk menyamakan skala dari masing-masing KPI.
Sehingga perusahaan mampu mengukur dan menentukan tingkat pencapaian dari masing-masing KPI. Scoring System menggunakan proses normalisasi Snorm dari De
Boer Triekeness dan Hvolby, 2000. Ada 2 kategori dalam proses normalisasi yaitu kategori Large is Better dan kategori Lower is Better. Proses normalisasi
membutuhkan nilai minimun dan nilai maksimum dari setiap KPI. Setelah melakukan perhitungan nilai aktual, maka langkah selanjutnya menentukan nilai minimum dan
nilai maksimum dari setiap KPI. Penentuan nilai minimum dan nilai maksimum diperoleh dengan melakukan wawancara dengan pihak manajemen dan juga diperoleh
dari data historis perusahaan.. Misal untuk KPI Percentage Of Adjusted Production Quantity
PAPQ dengan nilai minimum sebesar 0 dan maksimum sebesar 100. Proses normalisasi dapat dihitung sebagai berikut :
Rumus:= Smin
Smax Si
Smax −
− x 100
Kategori : low is better papq

Kemudian hasil dari perhitungan diatas dimasukan kedalam tabel hasil
normalisasi KPI Percentage adjusted production quantity pada tabel dibawah ini.
Untuk nilai Smax, Smin dan deskripsi proses normalisasi yang lebih jelas dan terinci dapat dilihat pada lampiran X. Berikut ini adalah hasil normalisasi untuk masing-
masing KPI : Tabel 4.37. Hasil Normalisasi KPI
