PENGEMBANGAN COST DRIVER MODEL COCOMO II DENGAN MODIFIKASI NILAI ATRIBUT PERSONEL UNTUK ESTIMASI USAHA PERANGKAT LUNAK (Studi Kasus)

Software project estimation is the process of estimating effort for software development. Effort is the effort (person/month), schedule (months) and cost. Estimation of software development is required to obtain results with high accuracy. Modification of the COCOMO II model adapted to the local programming environment is considered to improve the accuracy and prediction software. Personnel attribute cost driver of COCOMO II model is the attribute that assesses the work of the project based on human resource therefore considered important in the activities of an organization. This study used 29 datasets from software development company. The goal was to determine differences in outcomes effort estimation using COCOMO II and COCOMO modification. COCOMO II models provide the accuracy 13.1% and prediction 80% and the COCOMO modification models gives the accuracy 13.0% and the prediction 90%, so there is an increase 0,1% for accuracy and 10% for prediction
