Non-Functional Requirements Consulting
Make your existing software faster, more reliable, secure, scalable, and easier to maintain.
An application may deliver the right functionality but still struggle with slow response times, production failures, security concerns, or expensive changes.
dC0dez provides non-functional requirements consulting for existing software systems, including applications that are not undergoing migration.
Performance
Identify application and database bottlenecks, examine workload behavior, and establish measurable performance improvement targets.
Scalability
Assess capacity limitations, application architecture, infrastructure dependencies, and readiness for increased demand.
Security
Review relevant application security requirements, architectural controls, dependencies, and secure development considerations.
Reliability
Assess recurring failures, application dependencies, monitoring, fault handling, recovery arrangements, and operational risks.
Maintainability
Review code quality, modularity, technical debt, testing practices, documentation, and the difficulty of implementing changes.
What an NFR assessment can deliver
Depending on the agreed scope:
- Current-state observations
- Risks and technical gaps
- Measurable quality requirements
- Recommended improvement priorities
- Architecture and engineering recommendations
- Testing and validation approach
- Implementation roadmap
Improve existing software without automatically migrating it
NFR consulting can be performed independently of a modernization or technology replacement project.
We evaluate the existing application first and recommend changes based on its actual limitations.
Frequently asked questions
What is an NFR assessment?
An assessment of measurable system qualities, such as performance, reliability, security, scalability, and maintainability.
Can you assess applications built in Java or .NET?
Yes. Our NFR consulting offer is not limited to PHP.
Does every NFR assessment require code changes?
No. The initial outcome may be recommendations, architectural changes, operational improvements, or further testing.
