Project constraints are indisputable and critical restrictions on the project. One of the most common constraints is the necessity for your application to comply with domain-specific or local laws and regulations such as Payment Card Industry Data Security product development marketing Standard (PCI DSS) for FinTech or the abovementioned HIPAA for US healthcare applications. If you work with an outsourcing development team, another project constraint could be the need to work with your in-house team to determine a common approach to the project. Constraints canrsquo;t be ignored or omitted. And as a rule, they can slow down the software development lifecycle.
