ABSTRAK
Penelitian ini membahas mengenai permasalahan kegagalan pemenuhan pesanantepat waktu pada perusahan manufaktur produk-produk alat berat yangberkarakteristik make-to-order atau engineered-to-order. Penelitian ini terdiri daridua langkah analisa yaitu analisa makro menggunakan Process-basedPerformance Measurement Framework untuk mengidentifikasi proses yangpaling berpengaruh yang menyebabkan keterlambatan dan analisa mikromenggunakan Business Process Simulation. Tujuan penelitian ini untukmendapatkan perbaikan proses bisnis yang optimal sebelum benar-benarditerapkan. Hasil penelitian yang dilakukan menyarankan bahwa perbaikan prosesbisnis di area design engineering, PPC, Purchasing dan Production dapatmengurangi waktu siklus bisnis proses, sehingga dapat menurunkan tingkatketerlambatan.

Abstract
The focus of this study is about on-time delivery of order at a heavy equipmentsmanufacturer with characteristic make-to-order or engineered-to-order. This studycontains two stage analysis consist of macro analysis using process-basedperformance measurement framework to identify processes which have significantcontribution to create delay and micro analysis using business process simulation.The purpose of this study is identify improvements to optimize business processesto minimize tardiness on delivery time. The researcher suggests that processessuch as engineering design, PPC, purchasing and production to be improvedminimize business process cycle time to gain on time delivery within acceptablelevel.
