• Expectations can change midstream when
developing custom written software, making a
realistic budget difficult to project. As a result,
businesses often run out of money before the
project is completed.
• An experienced software team is needed.
Acquiring the right team can be costly. If the
people who are trained to use the program
resign then it will be some time before new
persons are trained, slowing down the
business functions

system that asks a patient a series of questions
