How Volume Categories Define Project Phases

When we talk about developing a car, the process often looks the same on paper:

idea → design → prototype → testing → production.

But in reality, the production category, how many vehicles will actually be built, changes everything. It shapes the level of detail, the investment, the validation effort, and even the way teams collaborate.

Let’s break it down.

What are the production categories?

1. High Volume: More than 100,000 units per year. Focus: efficiency, automation, robust processes, scalability.

2. Medium Volume Around 10,000 - 100,000 units per year. Focus: balance between flexibility and cost efficiency.

3. Low Volume Around 100 - 10,000 units per year. Focus: flexibility, craftsmanship, limited tooling investment.

4. Ultra-Low / Custom-Made Fewer than 100 units per year. Focus: exclusivity, hand-built production, customer involvement, innovation.

How categories impact project phases???

1. Concept and Planning

• High Volume: detailed market studies, complex business cases, long planning cycles.

• Medium Volume: targeted research with focused customer groups.

• Low Volume: shorter planning, often leveraging existing platforms.

• Ultra-Low: highly personalized, often initiated by specific customer demand or visionary concepts.

2. Design

• High Volume: extensive CAD modeling, rigorous risk analysis, wide-market appeal.

• Medium Volume: a balance between unique styling and reuse of proven elements.

• Low Volume: greater design freedom, often emphasizing brand character.

• Ultra-Low: bespoke approach, with customer input shaping the final product.

3. Engineering & Development

• High Volume: large-scale prototyping, structured validation plans with thousands of tests.

• Medium Volume: still structured, but with reduced scope.

• Low Volume: limited prototypes, reusing existing technologies where possible.

• Ultra-Low: very few prototypes, focused on performance and uniqueness.

4. Prototyping & Validation

• High Volume: multiple prototypes undergo extensive crash, durability, and compliance testing.

• Medium Volume: streamlined validation, still meeting regulatory and quality requirements.

• Low Volume: smaller test scope, supported by carry-over components.

• Ultra-Low: minimal prototypes, sometimes even customer-specific vehicles serve as validation.

5. Production Preparation

• High Volume: full-scale production lines, automation, high tooling investment.

• Medium Volume: partial automation, mixed with manual operations.

• Low Volume: flexible tools, higher manual involvement.

• Ultra-Low: almost entirely manual, highly customized equipment if needed.

6. Serial Production

• High Volume: thousands of vehicles daily, highly automated assembly.

• Medium Volume: tens or hundreds per day, semi-automated processes.

• Low Volume: tens per month, craftsmanship-driven assembly.

• Ultra-Low: a handful per year, fully hand-built.

7. Launch & Support

• High Volume: global launch campaigns, structured aftersales and recall processes.

• Medium Volume: targeted campaigns, customer loyalty focus.

• Low Volume: highly personalized customer service, premium support.

• Ultra-Low: direct relationship with customers, exclusive servicing, and individual follow-up.

All projects follow the same phases, but the scale, intensity, and focus shift dramatically depending on production volume.

High Volume projects demand industrial precision and efficiency, while Ultra-Low projects resemble craftsmanship, where each vehicle tells its own story
