Increasingly fierce business competition forces companies to look for innovations and strategies to maintain customer satisfaction and trust. PT Quinsha Trans Jaya, a tourism transportation services company, faced problems in providing service information and collecting customer feedback. To overcome this, a website-based customer relationship management system is needed. This system is expected to improve operational performance, facilitate purchases, and provide complete information to customers. The development of the system uses the Rational Unified Process (RUP) method and aims to help PT Quinsha Trans Jaya retain and attract new customers. The customer relationship management information system built will focus on service transactions through the website. Then this system has information features related to rentals and purchases as well as available promotions. There is also a reward feature, feedback from customers that helps companies increase customer loyalty.

PT XYZ is a private company in Palembang that supplies medical devices and equipment. This company conducts performance assessments every year to provide appropriate rewards in the form of gifts, bonuses or incentives to employees. In carrying out the performance assessment process for providing employee rewards, it is still done manually. This process is inefficient because it takes a lot of time, is prone to errors in calculation and it is not clear which aspects of the criteria are important. By using the Weighted Product methodology, this study tries to create a decision support system (DSS) that will simplify this evaluation procedure. This application is made website-based, using the laravel framework with the Iterative system development method. The results obtained indicate that the system can help companies improve efficiency by conducting automatic assessments, providing measurable weights, transparently and using the Weighted Product method for more accurate assessments. Overall, the system developed meets the research objectives.
