What factor has NOT contributed to the growth of commercial software development?

The growth of commercial software development has been driven by several factors, but the high demand for in-house development staff has not contributed to this trend. In fact, the rise of commercial software options has often allowed organizations to reduce their reliance on in-house developers. The availability of affordable, ready-to-use software products has enabled businesses to purchase rather than develop software solutions internally.

In-house development requires significant investment in recruitment, training, and maintaining personnel, making it less attractive compared to the low-cost options available commercially. The other factors listed, such as the emergence of industry-specific vendors providing tailored solutions and the trend toward downsizing which has led organizations to seek external vendors for their software needs, directly support the expansion of commercial software development, rather than the need for more in-house development positions.
