Software Design Specification (SDS)
Developing software for regulated pharmaceutical operations requires precision, verifiable control, and full compliance with global GxP standards. Our Software Design Specification translates high-level functional needs into a detailed, testable blueprint built for 21 CFR Part 11–compliant execution.
The SDS defines the complete software architecture, including data flows, interface points, and system behaviors required for validation. Every input and output is mapped with embedded verification logic. All system interfaces are documented in an Interface List to ensure traceability and seamless integration.
Security and data integrity are engineered from the start. The SDS outlines role-based access control, compliant electronic signatures, and a time-stamped audit trail for GxP-relevant actions. Core control features—alarm logic, configurable parameter settings, and change-controlled process values—are specified in detail. Software versioning and third-party components are fully documented to support long-term maintainability and audit readiness.
This structure accelerates validation by giving QA, IT, and engineering teams a clear, compliant foundation for testing and approvals.
Hardware Design Specification (HDS)
The Hardware Design Specification establishes the validated foundation for all physical components supporting GxP-regulated automation and information systems. It defines the requirements for hardware procurement, configuration, and installation to ensure compliance and reduce qualification risk.
The HDS specifies PLC platforms, HMI workstations, servers, networking equipment, and process-interface hardware, including required CPU, memory, storage, operating system versions, and firmware levels. System topology and physical layout are detailed to support proper environmental conditions—temperature, humidity, power—and to meet redundancy expectations such as UPS protection, RAID storage, and failover configurations.
These specifications directly support Installation Qualification (IQ) by providing a complete, verifiable record of the hardware environment, ensuring your system is built on a stable, compliant, and supportable foundation.
