Abstract
There was a time when technology came from big companies and a large number of products were developed and gave the birth to a new world which was a technology world. Each product was unique and it was developed by its own company. They did not want to share anything with other companies because they did not have proper guidance that how to implement the existing products with a new one so users have to wait for long time to get new products because it took much time to develop each and every component of the product. Today technology has reached its peak and there are many existing products available which can be used by the developers to create new products. The time has changed now developers have learnt many things from the past and they can easily integrate old technologies to new one. The dynamic software product line engineering is playing a vital role in our lives which one is teaching that how two products can be integrated if they are loose coupling status after introducing of this, it has solved many problems and also saving much money and time. Now big companies are ready to give some small task to the small companies and can ask the time of delivering products once its deliver big companies can integrate with their products and user can get new technology’s product in short time.
