Why is it cheaper in the long run to utilize software engineering methods?

Utilizing software engineering methods is particularly beneficial in the long run because they significantly help avoid expensive changes post-deployment. A key principle in software engineering is the emphasis on careful planning, rigorous design, and thorough testing throughout the development lifecycle. By adhering to these practices, teams can identify and address potential issues and requirements early, which reduces the likelihood of discovering major flaws or necessary feature changes after the software has already been deployed.

When changes are needed post-deployment, they can be disruptive and costly. This includes not only the direct costs associated with modifying the code but also the secondary costs involved, such as system downtime, potential loss of customer trust, and the impact on other ongoing projects. By investing time and resources into proper software engineering methods upfront, teams create systems that are more robust, meet user expectations, and require fewer adjustments after they are released. Thus, while the initial investment in software engineering practices might be perceived as higher, the long-term savings from avoiding late-stage changes make them more economical overall.
