The engineering process begins with a deep understanding of the problem, followed by rigorous experimentation, prototyping, and testing. Next, engineers leverage their knowledge of physics, calculus, electronics, materials science, and other fields to create new artifacts and machines that can solve complex challenges. 

But engineering is not just about building something new; it also involves creating systems and processes that enable the replication and scaling of solutions. These systems require different engineering focusing on standardization, quality control, and efficient production. 

In essence, there are two distinct types of engineering - one focused on innovation and problem-solving and another centered around production and efficiency. Both are critical to our modern society, as they allow us to create new solutions and ensure that those solutions can be produced at scale and made accessible to those who need them. 

Overall, engineering is an essential art that has driven countless technological advancements and helped us overcome some of humanity's most significant challenges. Whether we are designing new products, improving existing systems, or creating entirely new ways of doing things, engineering will continue to play a vital role in shaping our world for years to come. 

In software development, understanding the difference between engineering for production and engineering for innovation is crucial. 

Although the software is a relatively new industry, attempts to fit it into an industrial model have caused more harm than good. In particular, the practice of trying to apply concepts from other industries, such as architecture or manufacturing, has led to confusion and poor results. 

Fortunately, the advent of the Agile manifesto marked a turning point in the software industry leading to more efficient and effective development practices. 

With Agile, the software industry began to discover its identity as a unique field. However, the software industry still faces challenges in maintaining its independence. The specter of certifications and standardization looms large, threatening to stifle creativity and innovation in the industry. 

The software industry must continue pushing for its unique identity and methodologies. By emphasizing creativity, collaboration, and innovation, the software industry can continue to make groundbreaking strides in the years to come. 

Implementing so-called "good practices" in software development can waste time. Instead, it's more effective to define clear principles, design small software pieces, build them, and validate them as quickly as possible. 

Start-ups focus on fulfilling human needs rather than adhering to traditional software engineering practices. Therefore, when selecting a technical co-founder for your start-up, it's essential to choose someone who understands your goals and is willing to experiment and iterate quickly. 

The software development industry could be more efficient, with only 75% of projects making it to market. This inefficiency makes it clear that relying on so-called "experts" isn't always the solution. Instead, the key to creating a successful digital product is to approach each challenge as it comes, one by one, and solve them as quickly and effectively as possible. 

Successful software engineers recognize that they don't know everything and are willing to experiment and learn as they go. As a result, there are no shortcuts to creating a successful digital product. Still, by focusing on clear principles, small iterations, and rapid validation, you can increase your chances of success and ultimately create a product that meets your users' needs.
