Functions and features that have been deprecated will often still run in present adaptations of a software product and downward (often called backward compatibility), only to fail after an update has been distributed, released and/or installed. Prior to this, the development team responsible for engineering the product are tasked with identifying solutions for deprecated items. While software deprecation should ideally be seamless, it can often impact a product’s learnability and usability—particularly when changes directly impact user interaction.
Other times, however, the deprecation process is functional and involves the inner-workings of a product. Take an automobile, for example. A licensed driver may have a vehicle in compliance with current emission standards, but it’s effectively marked for redundancy whenever new standards are implemented. The vehicle is still operable and can be driven for a specified amount of time, but will eventually need to be brought up-to-speed, which may require the replacement of auto parts.
In software products and in others, a deprecated status alerts users that continued use of a marked feature is not admissible, and that appropriate actions should be taken to prepare for its removal. Software deprecation, in particular, is a better alternative to outright removal in that it allows time for developers to make the necessary code changes for new requirements. The following are reasons for why software features may be marked for deprecation:
Performance and security-related issues. Software design is an iterative process that typically progresses from prototypes and proof-of-concepts (POC) to production applications. But this does not mean that working products are without their flaws. Memory leaks, for example, can impact performance. These, along with security-related issues, may be deprecated while viable solutions are being researched.
Feature and functional enhancement. Companies and developers are constantly tweaking their products to remain competitive. Rolling out more powerful versions of a product’s most popular features may be good for performance, security and user engagement.
Fundamental structural changes. These modifications are introduced in newer versions of software, making them incompatible with certain features in older versions. Marking defunct items for deprecation becomes a logical process for phasing them out in a timely fashion.
Deprecation, in the context of technology in its entirety, is also used as best practices in both engineering and manufacturing. Hardware design would fall under the latter category. The case, however, would remain the same: Though a component may be available for use now, it may not be for long due to shortcomings and structural changes. This is a vital function in the Tech industry, and software deprecation, in particular, enables smooth transitioning in modernization projects, where data and features are transferred from legacy systems to contemporary ones.
