The N2 diagram presents the various functions and processes along with elements that need to be considered while forming engineering requirements in order to balance the input and output elements. It helps identify significant factors that impact the waste management system the most. Moreover, it also indicates that the flow of data is to be well aligned with the functioning of the various aspect of the waste management system. Only if these elements are achieved, it would be possible for the system to operate in an effective manner ( Prabir, 2012).
Surveillance and maintenance along with off site transport and on site handling form important elements of the N2 function diagram. It indicates that the process is quite complex, especially when applied to multiple routes and multiple sites. It is possible that there be careful handling of all materials in order to deliver efficiency in the process. In addition, it would also help to maintain similar processes and not make major changes in the system in order to preserve the prevailing functionality and balance the elements involved in the waste management system.
In this way, the requirements engineering of the waste management system offers an understanding of the process involved along with what steps can be taken to build an effective software system to help improve efficiency. It aims at understanding the requirements and process in order to build a system that can help from a strategic point of view. Waste management is a continuous process and it is essential that the process charted out be effective so that there is stronger efficiency. If this is not achieved, it would result in imbalance and problem in managing waste in a city. It is important that the process be strong enough to cater to the needs of the city along with incorporation of various changes that occur from time to time in the requirements. In these way, requirements engineering does help form a better process and also helps ensure better returns and benefits to the stakeholders (Prabir, 2012).
