Custom application development is like making a special computer program that does exactly what a business or person needs. It’s different from regular computer programs because it’s made to do specific things or solve special problems. A team first learns what the business or person needs to make a custom program. Then they plan and design the program before building it. They make sure it works correctly and fix any problems. Finally, the program is ready to be used. Custom programs can make things easier, improve how tasks are done, and make using the computer better. Even though making a custom program costs more initially, it’s often better in the long run because it’s made just for the person or business.
