Operating Procedure
At HydraTech, we follow a structured, end-to-end development process to ensure clarity and quality throughout every project:

Requirements Gathering — We start by understanding your product vision, technical needs, target market, and any certification requirements.
Proposal & Estimation — We provide a detailed scope of work, timeline, and cost estimate for your review.
Design & Development — Our multidisciplinary team (Mechanical, Hardware, Firmware, App, and AI engineers) collaborates in parallel to ensure system-level integration.
Prototyping & Testing — We build, test, and iterate on prototypes to validate the design before moving to production.
Manufacturing Support — We provide DFM/DFA recommendations and support small-batch and mass production.
Delivery & Post-Project Support — All source files, documentation, and reports are delivered upon completion. Post-project support is available on request.
