C4

The C4 model is a lean graphical notation technique for modeling the architecture of software systems.[1][2] It is based on a structural decomposition (a hierarchical tree structure) of a system into containers and components and relies on existing modelling techniques such as Unified Modeling Language (UML) or entity–relationship diagrams (ERDs) for the more detailed decomposition of the architectural building blocks. https://en.wikipedia.org/wiki/C4_model software architecture diagrams (more)

Six Sigma (6σ) is a set of techniques and tools for process improvement. It was introduced by American engineer Bill Smith while working at Motorola in 1986.[1][2] Six Sigma strategies seek to improve manufacturing quality by identifying and removing the causes of defects and minimizing variability in manufacturing and business processes. This is done by using empirical and statistical quality management methods and by hiring people who serve as Six Sigma experts. Each Six Sigma project follows a defined methodology and has specific value targets, such as reducing pollution or increasing customer satisfaction. The term Six Sigma originates from statistical quality control, a reference to the fraction of a normal curve that lies within six standard deviations of the mean, used to represent a defect rate (0.00034%). https://en.wikipedia.org/wiki/Six_Sigma

Designing for the Developers. After working in various Helsinki tech companies, Jori Lallo and Kaari Saarinen moved to San Francisco. There, they launched the collaborative (social) bookmarking system Kippt as part of Y Combinator’s Summer 2012 batch. Lallo sees Kippt as a precursor to Linear.app in that it was a practical tool with a small but passionate user base. Kippt was acquired by the cryptocurrency exchange Coinbase, and both of them joined that company in 2014, Saarinen as head of design and Lallo as a software engineer. Tuomas Artman moved to San Francisco by 2012, working at Groupon in engineering management. (more)

Product-Led, Customer-Driven. (more)
