The significant factor contributing to high costs in software projects is the changing software after it has been deployed. Once software is released, any required changes—whether due to bugs, evolving user needs, or shifts in technology—can be quite costly. This is because modifications in a live environment can lead to considerable expenses in terms of time and resources.

When software is updated post-deployment, it often requires revisiting the design, coding, and testing phases, which can dramatically increase the workload for development teams. Additionally, changes might affect interconnected systems or other functionalities, necessitating further changes and testing. This domino effect amplifies costs associated with project management, coordination, and quality assurance.

On the other hand, while investments in hardware and regular maintenance fees also affect the overall software project budget, they don't typically account for the extensive costs associated with adapting software to new requirements after it has been deployed. The complexity of the development staff can introduce challenges, but it is the ongoing need to modify software that most directly correlates with escalating costs and resource allocation.
