But since most systems do address some identifiable problem, we can simplify the discussion and avoid the problem/opportunity schizophrenia by focusing on the problem side of the coin only. Hence, a clear definition of a "risk" is a problem that could cause some loss or threaten the progress of the project, but which has not happened yet. Software specification is also known as requirements engineering and is defined as the identification of the requirements of the system and the limitations within which the system will operate, develop, or can evolve.
