Insufficient market demand research, vague product positioning (e.g., misalignment between functions and user pain points). Frequent demand changes leading to R&D rework and extended timelines
Unclear quality standards, lack of testing processes. Non-compliance with industry regulations/certifications (e.g., CE, FDA, environmental standards). Inadequate after-sales fault response mechanism, damaging brand reputation.
Substandard supplier qualifications, delayed delivery/unstable quality of core components. Immature production processes, leading to low yield and cost overruns. Inadequate capacity planning, failure to meet initial market demand.
Interdepartmental communication barriers like R&D, production, marketing, purchasing, delayed information synchronization. Loose control of timelines, milestone delays. Unreasonable resource allocation such as insufficient manpower, equipment, budget.
Inadequate technical feasibility assessment, failure to pre-resolve key technical bottlenecks. Insufficient prototype validation, resulting in performance/quality issues during mass production. Poor design-manufacturing compatibility (DFM/DFA design flaws).




Build on EVT optimizations to conduct more comprehensive and rigorous tests. In addition to enhanced functional and performance testing, include environmental adaptability tests (e.g., high-low temperature, vibration) and compliance tests (safety, compatibility) to ensure the design can stably produce quality products.
