Instead of creating an intermediate, 'half-step' product, commit to the harder but optimal solution if a plausible path exists. This avoids the wasted effort and sunk cost fallacy of a circuitous development path, even though it requires more upfront investment and conviction.
Manufacturing excellence is predetermined by how easily a product can be assembled. The product and its manufacturing line must be designed in parallel. If you wait to consider manufacturing until after the design is complete, you will have engineered in inefficiencies that are costly or impossible to fix.
When hiring, especially for early-career talent, prioritize a candidate's rate of learning and growth potential (their 'slope') over their existing knowledge and experience (their 'y-intercept'). This framework allows you to identify individuals who can scale into massive roles, even if they lack direct experience today.
Pushing for extreme speed does more than just accelerate timelines; it forces teams to triage ruthlessly. It creates a filter that naturally eliminates work on problems that don't absolutely need to be solved, preventing over-engineering and wasted effort. It's not about more hours, but higher focus.
A robust supply chain requires managing beyond your direct (Tier 1) suppliers. To ensure they can meet your growing demand, you must engage with their suppliers (Tier 2 and Tier 3) to identify and help solve their production constraints, effectively de-risking your own operations.
Truly exceptional hardware engineering leaders can operate across the entire abstraction stack. They connect a high-level business requirement, such as cost-effective installation, all the way down to the specific design choices of a subassembly, like the thickness of a rib on a metal casting.
Don't just rely on a supplier's quality control. To gain a deeper understanding and ensure parts meet your standards, design and build your own testing equipment. Then, provide these testers to your suppliers to use on their own lines, giving you direct insight into their process completeness.
To validate core assumptions quickly, structure your first real-world test for speed, not success. Even if you're confident it will fail, the learnings from a rapid first attempt—on suppliers, regulations, and execution—are far more valuable than prolonged planning for a perfect launch.
To foster a culture of transparency around constraints, use a physical object—like a ceramic turtle—that gets passed to the person or team who is currently the company's slowest link. This makes the bottleneck obvious in a lighthearted way and focuses collective attention on solving it.
Supplier negotiation strategy depends entirely on the product. For commodities (e.g., cat food), an aggressive, cost-focused approach works. For custom-designed components, where the supplier is a strategic partner investing in tooling for you, that same approach is destructive and short-sighted.
Early hardware prototypes don't need to be functional to be valuable. To test fundamental, real-world constraints—like whether a battery unit can fit through a standard yard gate—use the cheapest, fastest physical models possible, such as literal cardboard cutouts, to get immediate feedback.
An effective COO in a scaling company cannot manage everything at once. Their methodology should be to identify the most broken or critical process, focus their personal energy there to build a team and fix it, and then move on to the next major constraint.
