5 Strategies
to Simplify R&D and Reduce Costs
Cutting costs during research and development (R&D) is a vital goal for
companies looking to maintain a competitive edge. Elon Musk’s five-step cost-reduction method,
as discussed in his biography, offers a practical framework for achieving this. In this article, we
will explore the steps—questioning, eliminating, simplifying, and more—that can
significantly lower R&D costs.
Musk’s Five-Step Cost-Reduction Method
1. Question: Do You Really Need This?
Questioning is the cornerstone of Musk’s five-step cost-reduction method,
but it is also the hardest step to implement. He encourages developers to question every part of
their design, challenging established norms and assumptions. As Musk famously said, “Only
through relentless questioning can you truly solve problems.”
Here are some examples of the kinds of questions you might
ask:
• Why is the part’s wall thickness 4mm? You need to question it.
• Why is the part made from carbon fiber? You need to question it.
• Why is the part manufactured using machining? You need to question it.
• Why does this part exist in the first place? You need to question it. By questioning everything, you can identify unnecessary
complexity and opportunities for cost savings. For example, when designing the Starship rocket, Musk
questioned the widely accepted use of carbon fiber for the rocket’s shell. After some
calculations, he discovered that using carbon fiber would cost millions of dollars, while a
stainless-steel alternative could be achieved for just a fraction of the cost. This level of
questioning is what allows for real breakthroughs in cost reduction, while maintains the
functionality.
• Why is the part’s wall thickness 4mm? You need to question it.
• Why is the part made from carbon fiber? You need to question it.
• Why is the part manufactured using machining? You need to question it.
• Why does this part exist in the first place? You need to question it.
2. Delete: Cut What Doesn’t Add Value
After you’ve questioned every part of your product, the next step is
elimination—removing anything that doesn’t directly contribute to the product’s
functionality or value. As Musk advises, “Delete any part or process you can. You may have to
add some back later, but if you don't end up adding back at least 10%, then you didn’t
delete enough.”
This process of deleting could mean removing unnecessary
components, features, or processes. For instance, in the example shown in Figure-1, optimized design
was simplified by eliminating one part entirely. In the original design, two components (A and B)
were welded together to perform a clipping function. Part B, which was machined, was removed, and
its function was integrated into Part A, a sheet metal piece. By reducing the part quantities from
two to one, not only was the need for welding eliminated, but the overall cost was also
significantly lowered.
This method can yield substantial cost savings by eliminating
unnecessary complexity right from the design phase.
3. Simplify: The Power of Streamlining
Once unnecessary parts have been removed, the next step is to simplify or
optimize. This means refining the design and processes to make them as efficient as possible. A
streamlined design not only reduces costs by using fewer components, but it also speeds up
manufacturing, minimizes the risk of errors, and shortens assembly times.
In Musk’s five-step method, simplifying follows
elimination, ensuring that the remaining components and processes are working in the most
effective way. This could involve simplifying the manufacturing steps, selecting more efficient
materials, or reducing complexity in the assembly process. Ultimately, optimization drives both
cost savings and greater production efficiency.

4. Accelerate: Use On-Demand Manufacturing
The fourth step is to accelerate the cycle time. By speeding up processes,
companies can reduce development timelines and bring products to market faster, which ultimately
lowers costs.
One effective way to accelerate production is through
on-demand manufacturing, which has transformed traditional manufacturing by allowing companies
to produce only what they need, exactly when they need it. Particularly beneficial during the
R&D phase, where frequent design changes and iterative prototypes are common, on-demand
manufacturing enables low-volume production, helping companies avoid the financial burden of
overproduction or excess inventory. It also provides the flexibility to quickly adjust designs
without incurring the high costs of retooling or scrapping large production runs, thus
minimizing waste and accelerating time-to-market.
5. Automate: Boost Efficiency and Reduce Errors
The final step in Musk’s method is automation. Automating processes
reduces human error, increases efficiency, and shortens lead times. This could involve
incorporating robotics in assembly lines or using software to streamline workflows.
