A small company has developed a specialized software product that it configures specially for each customer. New customers usually have specific requirements to be incorporated into their system, and they pay for these to be developed and integrated with the product. The software company has an opportunity to bid for a new contract, which would more than double its customer base. The new customer wishes to have some involvement in the configuration of the system. Explain why, in these circumstances, it might be a good idea for the company owning the software to make it open source.

Please describe a situation in which a user engaged with a system, and comment on the discrepancy that you saw between the actions of the user and the evaluation made by the system.
The following situations are presented to you. I identify the issue associated with software crises in the context of a certain situation. Time slippage, cost slippage, failure at the client location, and interactable errors after delivery are all possible problems. Scenario A: A client has received software for financial systems that has been provided to them. The development team was notified by the customer that there was a problem with the system. Because the program was so large and complicated, the development team was unable to locate the source of the problem in the software. Scenario B: On August 15th, a polar satellite launch vehicle was planned to take out from Cape Canaveral, Florida. The autopilot for the rocket will be delivered on May 15th in preparation for the rocket's assembly. Because of the increased work put into the design and development of the software for the auto-pilot, the auto-pilot was supplied for integration on June 15th, rather than on the 15th of June…
Software engineering Question: Q.No.2. You intend to develop an online voting system for general elections. The major use cases of the voting model system include authorizing User that includes simple users and the system's staff. The system manages election districts and election units. The election unit is the system counterpart of the “election center”. In the conceptual model, the election center is central to the election procedure, as it is the fundamental tallying point. The votes are casted using machines provided by the state and are places at the election center. The fundamental assumption of this system is that almost all citizens above a certain age should be able to participate in the election procedure. It is practically infeasible for election staff to manually enter all electors into the system. The system should thus be able to import an electronic list of electors. This system also manages different political parties and their respective candidates participating in…
