7 Phases of System Integration Life Cycle1

A process to contact distinct systems that ensures an integrated system would function flawlessly with the other one  is called system the system integration process. This process allows the coordination of different computing systems and software applications functionally. System integration mainly contains seven distinct and crucial phases.

7 Phases of System Integration

  • Requirement and Specification:
    Before initiating to working on the actual system integration process; list out the detailed requirements your customer has given. Efficiency is required in framing the requirements of both the systems to be integrated to make this process easy and seamless.
  • Feasibility Analysis:
    Once the requirements, definitions and specifications referencing the systems to be integrated are listed down, feasibility analysis takes place. The feasibility study includes complete analysis of the system integration project based on the intense research to support the decision making process.
  • Architecture and Development:
    This is the system construction phase which includes system architecture plan regarding how the system should be integrated to the other comprehensive systems. Blueprints of the integration plan including the proposed architecture plan and much more are also created.
  • Management Plan:
    Once the complete plan of the system integration process is released, management plan follows next. Risk factor calculations, project execution plan, alternative listing etc. are the processes conducted in this phase.
  • System Integration Design:
    This is probably the fifth step of system integration life cycle that includes logical and physical designs created for the system that are to be integrated. Preliminary designs, detailed designs, system tests etc. are the processes included in this phase.
  • Implementation:
    Once the system design is ready, it is verified and implemented thoroughly. Before deploying the integrated systems, it is tested to give error-free solutions to the customer. In case of errors, integrator verify the system again to make it error-free. The final report consists of the error-free integrated system.
  • Evaluation:
    This is the last phase where the functioning of the integrated system is checked thoroughly. The evaluation phase includes checking, maintaining, modifying and enhancing the components.


System integration service offered by the professionals is 100% error-free as they follow all the seven phases mentioned above. System integration is the process that requires extensive research. Only an intense and insightful research results in the successful system integration. For instance, Magento & Quickbooks, Magento & SugarCRM, SugarCRM & QuickBooks, Magento & OpenERP etc. are the system integration services provided by the services providers that follow all all the above phases of the system integration process.


What is the system integration life cycle in order?

The system integration life cycle encompasses several stages to ensure seamless integration of various software components and systems. The typical order of these stages includes – Planning, Analysis, Design, Implementation, Testing, Deployment, Monitoring, Maintenance and Optimization, Documentation, and End-of-Life.

What is the integration phase of development?

The integration phase of development is a critical stage in the software development process where individual components, modules, or subsystems of a software application are combined and tested together. This phase focuses on ensuring that the integrated parts function harmoniously as a complete and cohesive system. 

Developers connect different pieces of code, APIs, databases, and services to validate data exchange, communication, and overall functionality. The integration phase helps identify and rectify any issues that may arise due to the interaction between various components, ensuring a smooth and reliable operation of the final software product.

What is the integration stage of the system development life cycle?

The integration stage in the system development life cycle is a pivotal phase where individual software components, modules, or subsystems are combined to create a unified and functional system. This stage comes after the completion of component development and involves connecting various parts of the system, such as databases, APIs, and interfaces, to ensure seamless communication and data exchange.
