What to do if the backend cannot implement a feature by the release date, but there is still time?

If the backend is not able to complete a feature by the release date, and there is still time, it is worth:

• Assessing the actual state of the task: understanding what exactly remains to be done, what risks and difficulties exist.
• Prioritizing functionality: possibly, some features can be postponed or simplified to release a minimally viable version.
• Discussing with the team and management: agreeing on changes in scope or deadlines.
• Using parallel work: if possible, involve additional developers or redistribute tasks.
• Automating and speeding up processes: for example, accelerating testing, using ready-made solutions.
• Regularly updating the status: so that all interested parties are aware of the progress and can make decisions.

The main thing is not to sacrifice quality and stability for speed; it is better to release less but reliably.
