The explosion of demand for application software outpaced the efforts of in-house programmers to develop applications from scratch. PCs did not have the power or capacity to replace mainframe computers, and companies struggled to develop their own applications. There was significant concern about the lack of software development productivity and quality, especially for these custom application development efforts. Best practices for software development emerged. 43 Firms at the lowest level of the CMMI® are considered to be ad hoc in their software development processes; firms appraised at levels 2, 3, or 4 are considered to have software development processes of increasing maturity that are defined, repeatable, and quantitatively managed, respectively, whereas firms appraised at level 5 are considered to be optimizing and operating at the highest level of software development capability.
