Manufacturers Embrace 'Shift-Left' for Faster, Cheaper, Greener Production
Manufacturers are adopting a new methodology, 'shift-left', to boost efficiency and quality. This strategy, adapted from software development, involves assessing manufacturability early in the design and planning stages using simulations and digital twins.
The 'shift-left' philosophy offers several advantages. It shortens launch timelines by identifying and resolving issues beforehand. It decreases scrap and rework costs by preventing defects. Consistent quality is ensured, and the workforce gains skills through early involvement in the process.
Implementing 'shift-left' is a phased journey. It commences by establishing model-based practices and progresses into a fully closed-loop environment. This approach originated in software development and has been mirrored in manufacturing through methods like concurrent engineering and APQP processes.
Key aspects of 'shift-left' in manufacturing include integrating inspection intent in CAD models and planning inspection and process monitoring early. In Smart Manufacturing, 'shift-left' thrives due to the digital thread, connecting design, process planning, production, inspection, and service.
While risks like inconsistent data or over-inspection exist, the benefits of 'shift-left' are substantial. It reduces time-to-market, lowers costs, and enhances sustainability. Metrology's role shifts from a reactive gatekeeper to an active design partner, making 'shift-left' a promising shift in manufacturing strategy.
