The benefits associated with software reuse are lower cost, better quality,
decrease in risk and potential for less stressful development process. however
in actual cases, the promises of decreased cost and risk are not always realized.
why? discuss thoroughly.

Software reuse is the technique through which updating the software system through the already defined components or assets of the software.This helps in increasing the productivity ,cost decrement , quality improvement etc.

But in actual case, the software reuse still persist high cost due to modification of inflexible designing of software .It also costs more than expected for the maintenance and training of software.

The security of the software is always at risk because of the usual and advanced hacking and attacking by the hackers even when the protect of software is high.Thus, these statements verify that the benefits of cost and security of software is not actually realized.
