This research is purpose to design and build a website-based employee performance assessment information system in Tirta Argapura Drinking Water Regional Public Company, Probolinggo Regency by using the calculation method TOPSIS (Technique for Order Preference by Similarity to Ideal Solution), MOORA (Multi Objective Optimization On The Basis Of Ratio Analysis), and (Weight Aggregated Sum Product Assesment) WASPAS. Then a comparison of the three methods with sensitivity test techniques is carried out to find the best method.

The development method used in this study is Rapid Application Development (RAD) with steps namely requirement planning, user design, construction, and cutover. Meanwhile, in testing the website that has been built, Blackboxand Whitebox testing methods are used. The test is carried out to ensure that the system that has been built does not have errors or defects that can affect the functionality of the system.

The results showed that the ranking or ranking of the final results of the TOPSIS, MOORA, and WASPAS methods showed the same results as manual calculations that were used as a reference in implementing these methods in designing employee assessment websites. The sensitivity test carried out has obtained results, namely the TOPSIS method of 0.081, the MOORA method of -5.542 and the WASPAS method of -5.964. Thus, the TOPSIS method is very stable to changes in the weight of criteria and it can be concluded that the TOPSIS  method is the best method in calculating the performance value of employees of the Tirta Argapura Drinking Water Regional Public Company, Probolinggo Regency.
