With respect to quality, some software is so fundamental and widely used that flaws are noticed immediately and fixed. Examples include microcode, firmware, operating system kernels, compilers, and embedded databases such as SQLite. Flaws in low-level software are generally much more destructive to value than flaws in high-level application software.
