Organizations as Production Technology

Show Notes:

Brian Potter, author of The Origins of Efficiency, explains his core model of efficiency, which includes five levers: production method, increasing production rate, lowering input costs, removing steps, and reducing variability.

The Work behind the Book

Brian discusses his background in the construction industry and his initial struggles in writing the book, including difficulties in explaining his thesis simply and coherently and the inspiration behind writing the book. He describes his process of iterating and refining his ideas, eventually classifying various strategies for improving productivity into a few key buckets.

Economies of Scale in the Construction Industry

The conversation turns to the book's argument that construction costs have not decreased, contrasting it with other manufactured goods. Brian explains the unique challenges in achieving economies of scale in construction, such as the difficulty in transporting buildings and the high costs of building materials and labor. He discusses the historical lack of economies of scale in large home builders and the challenges posed by different building codes, permitting jurisdictions, and environmental requirements. Brian emphasizes the difficulty of reducing input costs in construction due to the fixed nature of building materials and labor costs and explains how it compares to other industries and products.

How Transport Impacts Costs in Construction

The book explores the importance of reducing transport costs for efficiency gains, and Brian explains how the development of railroads in the 19th century enabled large-scale production by reducing transport costs and improving reliability. He discusses the impact of container shipping on modern manufacturing, highlighting the cost advantages of larger container ships due to geometric scaling and fixed cost scaling. Brian also mentions the historical example of iron stoves becoming more common after the development of railroads, which made it economical to transport them long distances.

How Changing Production Methods Reduce Cost

Brian is asked for an example of how changing production methods can unlock efficiency, and he talks about the discovery of a new process for making steel, which dramatically reduced the cost and time required to produce steel compared to the cementation process. He explains how the Bessemer process allowed for the widespread use of steel in construction, enabling the construction of buildings with steel frames. Brian highlights the importance of technological advancements in reducing the cost and increasing the efficiency of production methods.

Examples of Efficiency Gains: Increasing Production Rate

When asked for an example of how increasing production rate can lead to efficiency gains, Brian refers to container shipping, where larger ships have reduced costs per container due to geometric scaling and fixed cost scaling. He explains how spreading fixed costs over a larger output can make production more efficient. Brian mentions the example of Japanese factories in the 1980s, which were cheaper to build because they needed to store less inventory due to lean manufacturing principles.

How Lowering Input Costs Leads to Efficiency Gains

Brian explains how thread is an example of how lowering input costs can lead to efficiency gains. Thread became much cheaper due to technological advancements in spinning and weaving. He explains how cheaper inputs can lead to lower costs in the final product, making it more affordable for consumers. Brian also mentions the example of Iceland producing a large amount of aluminum due to its cheap hydroelectricity, which is a significant input cost in aluminum production.

Improving Efficiency Gains by Removing Steps

Brian shares an example of removing unnecessary steps in the production process at Tesla, such as removing sound-absorbing mats in the car that did not add value and the robots were having great difficulty installing. When they ran tests they found the mats didn't actually improve noise reduction. Brian explains how minimizing unnecessary steps can reduce costs and improve efficiency. He talks about common steps that can be removed ,and the importance of minimizing inventories and buffers in lean manufacturing to reduce costs and improve flow.

Reducing Variability to Improve Efficiency Gains

Brian discusses the example of semiconductor manufacturing, where reducing variability can significantly increase yields and reduce waste. He explains how precise control of the manufacturing process can lead to more reliable and efficient production. Brian mentions the importance of reducing errors and failures in production processes to improve efficiency and reduce costs.

Evolution of Construction Physics

Brian explains how his Substack started focusing on construction and housing but expanded to include topics like the energy grid, energy tech, institutions, innovation dynamics, and global production. He explains how his work at a construction startup influenced the topics he covered in the Substack, and how he began by just following his interests. However, later a thinktank became a fan of his Substack and sponsored him. Brian also mentions the support he received from the Institute for Progress, which helped him expand his reach and focus on broader topics.

The Role of Institutions and Organizations as a Production Technology

Brian explains that organizations and the way work is structured can be a significant factor in productivity improvement. He discusses the importance of lean manufacturing and other industrial improvement methods in rearranging work to improve efficiency. He also mentions that organizations and their patterns and behaviors can embody important technological knowledge and practices.

Research and Primary Sources

Brian shares that he is primarily a text-based researcher and relies on books, manuals, and other written sources for his research. He explains that his experience working in the construction industry informs his understanding of different industries and production methods. He also discusses the importance of finding sources that provide detailed information about production processes and technological advancements, and why he doesn't talk to much about manufacturing in China.

Future Plans and Final Thoughts

Looking ahead, Brian has ideas for new books, including a short history of the shipbuilding industry. He also discusses his ongoing work on the Substack Construction Physics and his focus on following his interests and learning more about various topics.
