The lifecycle approach of a computerized system allows for its proper management, aiming to plan, implement, operate, and retire each system with control and traceability, always protecting data integrity. This approach is realized through distinct phases that allow the system to be managed in a structured manner aligned with Good Practices. Each phase and its role within the lifecycle are presented below. ## **1. Concept Phase: Where It All Begins** The cycle starts with the concept phase, where process needs are identified, user requirements are defined, and risks and suppliers are evaluated. Proper planning at this stage ensures that the selected technological solution meets its intended use and prevents rework during development.   ## **2. Project Phase: Design, Configuration, and Verification** Once the concept is defined, the project phase follows, during which the system is designed, configured, verified, and documented. Tests are executed here to demonstrate its correct operation, and the controls and procedures that will allow the system to be operated safely are established. With this, the system is ready to be released for use.   ## **3. Operation Phase: Maintaining the Validated State** During the operation phase, the primary objective is to maintain the validated state throughout the system's use. This involves managing changes, incidents, access, backups, and periodic reviews to ensure that data remains complete, consistent, and accurate. This is the longest stage of the cycle and where the day-to-day reliability of the system is demonstrated.   ## **4. Retirement Phase: Closing the Cycle Without Risks** The cycle concludes with the retirement phase, in which the system is discontinued in a controlled manner. This includes safeguarding or migrating data, removing access, disconnecting interfaces, and ensuring that no information remains exposed. Proper retirement preserves historical traceability and prevents security risks or data loss.   ## **Conclusion: An Approach That Guarantees Control and Reliability** Collectively, this approach enables the validation of computerized systems, ensuring control throughout their entire lifespan, supporting decision-making, reducing risks, and strengthening the efficiency and reliability of digital processes in regulated environments. ![Life Cycle of CS\_MX\_Blog-1](https://blog.pqegroup.com/hs-fs/hubfs/Life%20Cycle%20of%20CS_MX_Blog-1.jpg?width=2000&name=Life%20Cycle%20of%20CS_MX_Blog-1.jpg) ## Are you compliant ?
