How it all started

Necessity begets ingenuity

In the middle of the 20th century, Japanese companies had to deal with short resources. Therefore, efficiency became a key issue of entrepreneurial activities in Japan. New methodical approaches arose.

High quality standards, customer satisfaction as a top priority and the concept of the collective above the individual were core values and set the foundation for process improvement methods like Lean, Kaizen and Six Sigma. 

Quantitative measurability and delivery reliability were significant parameters that framed the development of those methods.

From frustration to iteration

­The story of Agile began in the American software industry. In the 1980s, the traditional linear waterfall project planning was stretched to its limits concerning software development. The approach had to switch from linear to circular processes to meet customer expectations. The PDCA-Cycle was born. 

Later, the PCDA-Cycle and the waterfall process were combined. This is how Scrum was created.
