This paper explores the application development phases of the online version of Cow Herd Appraisal Performance Software (CHAPS). Beef producers and Extension professionals have been using CHAPS since 1985 as a herd management tool. North Dakota State University (NDSU) Extension Service and North Dakota Beef Cattle Improvement Association (NDBCIA) developed the first version of CHAPS in 1985. There is two more development iteration of this application named CHAPS 2000 and CHAPS 2020. To modernize the CHAPS application, the NDSU Extension decided to develop an online version of the CHAPS application, and this version is called CHAPS Online. This paper focuses on the development process of the CHAPS Online application and how it is different from the CHAPS 2020.
