Excerpt from the full article: “Hardware In Hard Times: How To Succeed In Innovating When The Industry Collapses”.
“Compared to software development, where a bug can be fixed in the next release, changes in hardware products often take a lot of time and money for new components, production tooling, and certifications. Hardware development has a golden rule of 1:10:100. It takes only 1 hour to correct the same issue during the design stage, 10 hours when a prototype is made and over 100 after the first batch is produced. The same rule applies to cost. However, when designed properly, hardware products may be a source of revenue for years. Thus, finding a balance between rapid development and investing sufficient time in detailed engineering is the main responsibility of the product owner.”
