1. Limited compatibility: Different components may not be compatible with each other, leading to the need for additional modification before integration.
2. Complexity: In complex systems, it becomes very challenging to integrate different components since the system design, and architecture may not be fully understood.
3. Time constraints: In some cases, integration may require a huge amount of time to complete. This could lead to delays in final implementation.
4. Interoperability: Different components or systems are used, each with its proprietary protocol or data format, making it difficult to integrate them seamlessly.
5. Resource allocation: Resource management can also pose a challenge, as architecture integration requires many resources, such as manpower, software, hardware, and time.
6. Security: Integrating different systems can create security risks, such as exposing vulnerabilities or gaps in security measures.
7. Testing: Testing can be time-consuming as a comprehensive approach is required to test the integrated system to ensure functional efficiency and operability.
