Engagement Models & Pricing

I offer two distinct yet supplementary engagement models: flexible consulting support and clearly defined delivery packages with fixed pricing.

Engagement Models & Pricing

Delivery Packages (Fixed Price)


This model is designed for well-defined project phases where scope, outcomes, and budget can be agreed upon upfront. Billing is based on deliverables—not time—providing full cost transparency.

Examples of typical packages:

  • Analysis & Design: e.g., Use Case Analysis, Functional Architecture
    Pricing: Fixed fee based on scope and complexity
  • Methodology Setup: e.g., Customized SysML profiles, modeling guidelines
    Pricing: Milestone-based
  • Specification Development: e.g., Interface-Specifications, System-Requirements
    Pricing: Milestone-based or fixed fee
  • Architecture & Quality Reviews: e.g., System Architecture Assessment
    Typical scope: 5–10 days equivalent

Each package is tailored to your specific context. A clear definition of scope, deliverables, and acceptance criteria is agreed upon upfront to ensure predictable outcomes.


Engagement Models & Pricing

Contingency Model (Hourly Rate)


Standard Rate: € 112/hour (all-inclusive within the DACH region)

Efficiency through Experience: Due to my extensive experience in complex environments, I focus on rapid problem understanding and decision-oriented work. Tasks typically planned with 100% effort are often completed in 60–80% of billable hours. This significantly reduces the effective project budget.
