Abstrak

Software memegang peranan penting pada sebuah bisnis untuk mempercepat dan mengatur proses bisnis secara lebih baik. Proyek pengembangan software seperti halnya proyek-proyek pada umumnya membutuhkan estimasi yang tepat agar dapat berjalan dengan baik dan lancar. Metode use case points digunakan untuk mengestimasi software berbasis obyek dengan tingkat akurasi cukup baik. Nilai Effort Rate (ER) yang digunakan dalam metode estimasi UCP memiliki nilai yang bervariasi mulai dari 4 sampai 35 man-hours, sehingga akan membuat sulit pengembang pemula untuk menentukan nilai ER yang tepat. Thomas Tan dalam disertasinya berjudul ‘Domain-Based Effort Distribution Model For Software Cost Estimation’ menunjukkan bahwa setiap aplikasi memiliki distribusi effort yang berbeda-beda sesuai dengan karakteristiknya yang berjumlah 21 domain. Dari hasil penelitian yang dilakukan terhadap proyek sistem penjualan barang, didapat nilai aktual effort dan cost mendekati nilai estimasi yang dilakukan. Nilai estimasi effort 381,3 jam dan aktual effort 407.5 jam, sedangkan estimasi cost IDR 39.804.236 dan aktual cost IDR 47.675.417  sehingga didapat nilai deviasi effort 6,4% dan deviasi cost 16,5%.

Abstract

Software plays an important role in a business to accelerate and manage business processes better. Software development projects as well as projects generally require the right estimates to work well and smoothly. Use case points method is used to estimate object-based software with good accuracy. The value of the Effort Rate (ER) used in the UCP estimation method has values range from 4 to 35 man-hours, so it will make it difficult for novice developers to determine the exact ER value. Thomas Tan in his dissertation entitled 'Domain-Based Effort Distribution Model For Software Cost Estimation' shows that each application has a different distribution effort according to its 21 domain characteristics. From the results of research conducted on the project sales system goods, obtained the actual value of effort and cost close to the estimated value made. The estimated value of effort is 381.3 hours and 407.5 hours actual effort, while the estimated cost is IDR 39,804,236 and the actual cost is IDR 47,675,417 to get the value of deviation effort 6,4% and deviation cost 16,5%.

 

Keywords: Estimate effort and cost software, use case points (UCP), application domain.
