Which phaseof sdlc can be sources for errors?

Errors can originate in multiple phases of the Software Development Life Cycle (SDLC), but they are most commonly found during the requirements gathering phase, where misunderstandings or incomplete specifications can lead to flawed designs. Additionally, the design and coding phases are critical, as poor design choices or coding mistakes can introduce significant issues. Testing is also a phase where errors may be identified, but if previous phases were not conducted thoroughly, it may be too late to address foundational problems effectively. Regular reviews and quality assurance throughout all phases can help mitigate these risks.
