When developers develop a system, they need to know exactly what it should do to develop the system correctly. If they don't understand properly, a strange system can be developed.

System requirements can help to develop a system that satisfies Stakeholders and develop an efficient system.]]> 2021-11-08 07:56:36 UTC https://padlet.com/junyoungjoun/de8hvla4a79xplgc/wish/1874419978 Why is requirements specification so important? junyoungjoun https://padlet.com/junyoungjoun/de8hvla4a79xplgc/wish/1874421682 (p. 12)

But it takes a long time.]]> 2021-11-08 09:20:08 UTC https://padlet.com/junyoungjoun/de8hvla4a79xplgc/wish/1874574131 What entities can you think of in Students Enrollment System? junyoungjoun https://padlet.com/junyoungjoun/de8hvla4a79xplgc/wish/1874581634 (p. 11)
