A structured approach, from specification to handover.
Every successful industrial automation project rests on a rigorous methodology. From the initial expression of requirements to final system handover, each stage must be managed with precision to deliver a solution that is compliant with specifications, validated by the client, and maintainable over the long term. At AUTOM Technologies, our project methodology is inspired by the best practices of industrial engineering: structured phases, documented deliverables at each milestone, and close collaboration with client teams throughout.
Our 6-phase methodology
Phase 1 — Studies and specifications
The project begins with a thorough analysis of client requirements: review of P&IDs (Process and Instrumentation Diagrams), functional specifications, I/O lists, equipment data sheets and applicable standards. We produce User Requirement Specifications (URS) that serve as the contractual reference for the entire project. This phase also includes the choice of technical architecture — PLC platform, SCADA, communication network — and the overall planning of the project phases.
Phase 2 — Design and detailed engineering
Based on the specifications, we produce detailed design documentation: Functional Design Specification (FDS) and Detailed Design Specification (DDS), software architecture design, HMI screen mock-ups, network architecture diagram and interface specification with existing systems. In regulated sectors (pharmaceutical, nuclear), this phase includes the Design Qualification (DQ) document. Every design choice is documented and traceable to the initial requirements.
Phase 3 — Development and programming
This is the coding and configuration phase: PLC programming (IEC 61131-3), SCADA/HMI development, communication network configuration and integration of the various subsystems. We apply a structured development approach: modular code with reusable function blocks, inline comments, systematic version management (Git), and progressive unit testing throughout development. Programming is systematically reviewed by a second engineer before FAT.
Phase 4 — Factory Acceptance Testing (FAT)
FAT is a critical phase: it is the point at which we formally validate, with the client, that the developed system meets all specified requirements. FAT is carried out in our workshop on a test bench that faithfully simulates field conditions: simulation of field signals, simulation of communication faults, testing of all operational sequences and verification of safety functions. For each test, a FAT protocol records the expected result, actual result and acceptance status. Any non-conformity detected during FAT is corrected before shipment to site.
Phase 5 — Site commissioning (SAT)
Our engineers travel to the client site to install equipment, carry out loop testing (loop checks), bring the system into operation with real field equipment and train operating teams. The SAT (Site Acceptance Test) follows the same procedure as the FAT, but this time with the actual installation in real conditions. Particular attention is paid to the handover to operating teams: provision of all technical documentation, user manuals and training adapted to the level of the operators.
Phase 6 — Support and maintenance
Our relationship with clients does not end at commissioning. We offer corrective and preventive maintenance contracts, remote maintenance services (VPN access, remote monitoring), software update assistance and technical telephone support. In the event of a breakdown, our ability to remotely diagnose problems and, if necessary, to travel on site rapidly, ensures the minimisation of production downtime for our clients.
