Implementasi Metode Personal Extreme Programming dengan Metode Prioritas MoSCoW-AHP dalam Pengembangan Sistem Pengelolaan Apotek (Studi Kasus: Apotek Rajawali)

The development of information technology demands the existence of information systems that are capable of improving the efficiency and accuracy of data management, including in the pharmaceutical sector. Apotek Rajawali still performs data management manually, such as recording sales and purchases, monitoring drug stock, and preparing reports. This condition has the potential to cause delays in processes and recording errors. This study aims to develop a web-based pharmacy management system by applying the Personal Extreme Programming (PXP) method combined with the MoSCoW–Analytical Hierarchy Process (MoSCoW–AHP) prioritization approach, as well as to measure the usability level of the resulting system. The PXP method is used as the system development framework, while MoSCoW–AHP is applied at the planning stage to determine the priority of requirements in a structured and quantitative manner. The system development resulted in 26 user stories with a total of 38 story points completed in three iteration cycles. Usability testing was conducted using the System Usability Scale (SUS) method involving six respondents. The results of the study show that the implementation of MoSCoW–AHP is able to reduce the number of pairwise comparisons from 325 in pure AHP to 100 comparisons, or decreased by 69.23%. In addition, the system obtained an average SUS score of 84.58, which is included in the acceptable category, obtained grade A, and has an adjective rating of excellent. These results indicate that the system has a high level of usability and is able to support the operational activities of Apotek Rajawali effectively.
