Does the PSP facilitate component-based development and reuse?
In the PSP, planning begins by producing a conceptual design and identifying the opportunities for using or building reusable components. Estimating includes an estimate of the reusable components and the components that will be built to be reused. Two measures are included for tracking reuse: %Reuse (percentage of code that was reused) and %NewReuse (percentage of code that was built to be reused).
