Penelitian ini akan membahas mengenai implementasi sistem manajemen kualitas ISO 9001:2008 Klausul 8 (pengukuran, analisis, dan perbaikan) pada proyek konstruksi yaitu proyek Tamansari Panoramic Apartment PT Wika Realty. Analisis dilakukan dengan melakukan perbandingan antara standar ISO 9001:2008 Klausul 8 dengan implementasinya pada proyek Tamansari Panoramic Apartment PT Wika Realty. Penelitian dilakukan dengan melakukan wawancara, observasi data, dan studi literatur. Penelitian difokuskan pada kesesuaian Klausul 8 (pengukuran, analisis, dan perbaikan) pada dokumen proses yang digunakan sebagai pedoman dalam mencapai keefektifan pelaksanaan proyek. Hasil dari analisis penelitian ini adalah telah diterapkannya sistem manajemen kualitas ISO 9001:2008 Klausul 8 (pengukuran, analisis, dan perbaikan), namun terdapat implementasi yang belum sepenuhnya dilakukan dan secara konsisten diterapkan. Hal tersebut karena adanya pemahaman prosedur yang rendah, terjadi ketidakseimbagan antara jumlah karyawan dengan kompleksitas pekerjaan, serta kurangnya komitmen karyawan dalam melaksanakan prosedur kerja. Sementara untuk faktor kunci keberhasilan, ditemukan bahwa faktor kunci keberhasilan biaya telah memberikan dampak positif pada efisiensi biaya, sedangkan untuk komitmen dan budaya belum dilakukan dengan baik.
