Non Functional Requirements
When developing Software as a Service (SaaS) applications, non-functional requirements play a crucial role in ensuring the success and effectiveness of the software. Here are some non-functional requirements to consider when making SaaS software:
1. Availability: SaaS applications should have high availability to ensure that users can access the software and its services whenever needed. This requirement may involve redundancy, failover mechanisms, and monitoring systems. Establish internal SLO/SLA/SLIs as applicable.
2. Scalability: SaaS applications should be scalable to handle varying workloads and accommodate a growing number of users. This requirement may involve horizontal scaling, load balancing, and auto-scaling capabilities.
3. Performance: SaaS applications should perform efficiently and provide responsive user experiences. This requirement may involve optimizing database queries, caching mechanisms, and minimizing latency.
4. Security: SaaS applications must prioritize security to protect user data and ensure the privacy and integrity of information. This requirement may involve implementing strong authentication, encryption, data backup, and compliance with industry regulations.
5. Data Integrity and Backup: SaaS applications should ensure the integrity and accuracy of data by implementing appropriate data validation and backup mechanisms specially when data migration is involved. This requirement may involve regular data backups, data redundancy, and disaster recovery plans.
6. Compliance: SaaS applications must comply with relevant industry standards, regulations, and data protection laws. This requirement may involve adherence to GDPR, HIPAA, PCI-DSS, or other applicable regulations.
7. Integration: SaaS applications should be capable of integrating with other systems and third-party services. This requirement may involve providing APIs, webhooks, or other integration mechanisms.
8. User Experience: SaaS applications should provide a user-friendly and intuitive interface to ensure a positive user experience. This requirement may involve usability testing, responsive design, and accessibility considerations.
9. Monitoring and Logging: SaaS applications should have robust monitoring and logging capabilities to proactively identify and resolve issues. This requirement may involve implementing logging frameworks, real-time monitoring, and alerting systems.
10. Support and Maintenance: SaaS applications should have proper support and maintenance processes in place to address customer concerns, provide timely updates, and ensure the software remains up to date.
Remember that these non-functional requirements may vary based on the specific nature of your SaaS application, target audience, and industry requirements. It’s essential to carefully analyze and document these requirements to guide the development process and ensure the successful delivery of a reliable and effective SaaS software.
