Why is cross-functional collaboration so difficult in large vehicle / product projects? Why is the “Project Part Task List” so critical in large-scale projects?
+
Typical root causes include: inconsistent core part lists, fragmented information, unsynchronized changes, misaligned departmental priorities, and lack of standardized APQP working mechanisms.
At the core of all these issues lies the absence of a unified collaboration system built around the Project Part Task List. As the single source of truth for project collaboration, this task list defines:
• Which parts need to be developed?
• Who is responsible for each part and which suppliers are involved?
• Where do APQP, procurement, process engineering, and quality tasks originate?
• How are changes synchronized and what is their impact scope?
• Which parts have risks, schedule delays, or PPAP issues?
Without a unified project part task list, large projects inevitably fall into multiple crises: misaligned understanding of the same part across departments, delayed supplier task initiation, late PPAP and prototype deliveries, and concentrated issues before SOP.
Therefore, a unified Project Part Task List is the fundamental infrastructure for large-scale project collaboration.
Why is collaboration efficiency between enterprises and suppliers in APQP/PPAP processes generally low?
+
Typical problems include:
• Suppliers do not understand task priorities.
• Repeated and inconsistent document submission and review processes.
• Enterprises cannot track supplier progress in real time.
• Issues and closures are difficult to trace.
• Multiple communication rounds relying on emails, chat groups, and spreadsheets.
The root causes are:
• Lack of a supplier collaboration platform.
• Lack of task-driven mechanisms.
• Lack of standardized workflows and deliverable requirements.
• Insufficient project-level process transparency.
Ultimately, enterprises and suppliers lack a unified information source for parts, tasks, changes, and APQP status.
Why does change management easily lose control in large projects? How can enterprises achieve “change-driven collaboration and synchronization”?
+
Change becomes uncontrollable mainly because:
• Design changes are not delivered in time to procurement, quality, and suppliers.
• A single change affects multiple parts, suppliers, and plants.
• Manual synchronization causes omissions and delays.
• Impacts on cost, risk, PPAP, and prototype delivery lack visibility.
To achieve “change equals synchronization”, enterprises need to:
• Define explicit relationships between changes, parts, suppliers, and APQP tasks.
• Automatically distribute cross-functional change tasks.
• Visualize change impacts (delivery, cost, risk, prototypes).
• Automatically update data based on a unified project part list.
Change management is not about managing the change itself, but about managing its impact chain.
Why do “prototype development and approval” often suffer delays, rework, and quality inconsistency in large vehicle projects? How can enterprises ensure a controllable prototype process?
+
Prototype development and approval are highly interdependent across R&D, procurement, quality, and suppliers — and are often the root cause of project delays. Typical problems and solutions include:
• Unclear or inconsistent technical requirements. Enterprises must use a unified Project Part Task List + Latest Drawing Repository as the single source of truth (SSOT) for prototype technical requirements.
• Non-standard procurement processes and unclear supplier responsibilities. Enterprises must establish a structured prototype ordering and task workflow, automatically generating prototype batches, drawing versions, process requirements, supplier milestones, and logistics requirements — synchronized with suppliers in real time.
• Inconsistent approval standards and opaque processes. Enterprises must establish a unified prototype approval workflow covering technical, quality, performance/testing, appearance/packaging approval, deviations, and temporary approvals — enabling full traceability from submission to approval.
• Delayed synchronization of changes during prototype phases. Enterprises must ensure that design changes automatically trigger prototype tasks, identify impacted parts, push change information to procurement and suppliers, update prototype order versions, and visualize risks and delays — minimizing rework and misproduction.
• Disconnection between prototype approval and APQP/PPAP. Enterprises must treat prototype approval as a prerequisite input to PPAP, linking it with DVP&R, tooling/mold status, and supplier APQP progress to form an end-to-end quality planning chain.
Why are supplier quality issues difficult to detect and control in mass production? How can enterprises improve?
+
Key causes include:
• Insufficient APQP execution in early phases, allowing hidden defects to surface only in mass production.
• Supplier process changes not synchronized with OEM.
• Lack of cross-project and cross-product supplier quality data accumulation.
• Delayed risk warnings, with issues only discovered after escalation.
Improvement approaches include:
• Linking APQP results with mass production quality data.
• Integrating supplier change management with enterprise APQP processes.
• Building digital supplier risk and performance profiles.
• Establishing cross-project, cross-product supplier quality analytics.
In fact, over 70% of mass production quality issues originate from insufficient APQP execution.
