                                       Requirements Change Management                                                                      Abstract: Requirements change is an inevitable activity and may occur thanks to changes in user demands, increased understanding of the stakeholders, customer organization, project vision, requirements specification and availability of technological solutions. User requirements for software development are becoming more complicated and are changing all the time. Not only should the wants engineering process be well-organized but requirements change management should even be effective, especially for complex systems. However, the software engineering methodology employed also can make requirements change difficult to manage.   Although requirements change management (RCM) is not a straightforward process in collocated software development, the presence of geographical, social, cultural and temporal variations makes the process more diffi

What is the Fourth Industrial Revolution?  Klaus Schwab, founder and executive chairman of the Geneva-based WEF,  published a book in 2016 titled "The Fourth Industrial Revolution" and coined the term at the Davos meeting that year.  Schwab argued a technological revolution is underway "that is blurring the lines between the physical , digital and biological spheres."  Simply put, the Fourth Industrial Revolution refers to how technologies like  artificial intelligence , autonomous vehicles and the internet of things are  merging with humans' physical lives . Think of voice-activated assistants, facial ID recognition or digital health-care sensors.  Schwab argued these technological changes are drastically altering how individuals, companies and governments operate, ultimately leading to a  societal transformation similar to previous industrial revolutions.

Figur: AIOT What is the web of Things? The Internet of Things, or IoT, refers to the billions of physical devices round the world that are now connected to the web, all collecting and sharing data. because of the arrival of super-cheap computer chips and therefore the ubiquity of wireless networks, it's possible to show anything, from something as small as a pill to something as big as an aero plane, into a neighborhood of the IoT. Connecting up of these different objects and adding sensors to them adds A level of digital intelligence to devices that might be otherwise dumb, enabling them to speak real-time data without involving a person's being. the web of Things is making the material of the planet around us smarter and more responsive, merging the digital and physical universes. What is an example of an online of Things device? Pretty much any object is often transformed into an IoT device if it is often connected to the web to be controlled or communicate i
