Please resubmit the question and specify the other subparts (up to 3) you’d like answered When a component is reused efficiency is increased as much of the component is already completed, consistency is increased as control and scalability is enhanced on it, testing is reduced as components are already tested, etc. Step 2 a) Three components to be reused can be : Tab control Dialog control Calendar control Other parts maybe of login registration page b) Tab control : For flexible navigation a customized tab control can always be reused in different applications. This will increase efficiency . Dialog control : To manage some kind of action when one exit app or switch between different sections can be reused.
