# Lean Sourcing In the **multi-speed delivery model** of **./pulse**, where hardware and software evolve at different paces, **traditional sourcing and requirements processes become bottlenecks**. **Lean Sourcing** enables **modular, agile procurement** by **decoupling HW and SW**, supporting **just-in-time sourcing**, and aligning supplier contracts with **continuous integration cycles**. This approach **reduces dependencies, accelerates updates, and ensures supply chain resilience**, making it essential for **Software-Defined Vehicles (SDVs)**. * **Lean Requirement Management (LeanRM)** simplifies requirements management by **focusing on value, reducing waste, and ensuring traceability** at the speed of modern development. It replaces **rigid, document-heavy processes** with **adaptive, iterative requirement flows** that match the pace of SDV innovation. * **Supply Chain Management for SDVs** shifts from **static, hardware-driven logistics** to a **modular, software-first ecosystem**. It **unbundles HW and SW** and enables **agile contracts with fewer fixed requirements**, allowing for **faster integration, reduced risk, and better alignment with over-the-air (OTA) updates**. Together, these approaches create an **adaptive framework** that enables SDVs to evolve **continuously, efficiently, and at scale**. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://www.sdv.guide/pulse/lean-sourcing.md?ask= ``` The question should be specific, self-contained, and written in natural language.
