Toyota is known - among other things - for the Just-In-Time (JIT) concept, which basically means you should only do something when there is an actual need.Ī product with a quality problem is unfinished work seen from a Toyota (or “lean”) perspective. Toyoda Sakichi later sold his patent for the loom and gave the large sum of money to his son to create an automobile company, which of course was named Toyota. When faults are not detected by the one producing them quality assurance quickly becomes a social (or even sociological) problem.īut if we cannot build quality in automatically, what can we do?

The bigger the system, the more people will be involved.

The longer it takes for the result to come back, the less value it will have.

The bigger the system, the longer time it will take to run the test suite that truly proves the system is working (unit testing does not do that, but that is another topic).

The problem can be boiled down to these two aspects: But as long as time passes between doing work and seeing the result of our work, we will fight a Sisyphean battle for quality, because we cannot genuinely build quality in. Today we have better support for automating all of this than ever before.

Beyond that, we still have these longish feedback cycles, be it manually running unit tests or waiting on the automatic build or system tests run by our continuous integration (CI) system.Įven worse, most popular modern languages and environments, such as Python, Java Script or Ruby, don't have incremental feedback mechanisms you have to run them to see if they are even syntactically correct. Incremental compile with visual feedback is a small step toward the automaticity of the Sakichi loom.

He thereby also invented the concept of “stop-the-line” to build quality in. In the first post of this series, I wrote about Toyoda Sakichi, the founder of the Toyota industries, who invented a loom that would automatically stop when a thread broke in the 1920. In this post, Peter explains the importance of combining automation with human touch in order to create products of the highest possible quality.

This three-part series written by Peter Antman takes a journey through the evolution of quality assurance, takes a look at the current state of 'quality' in the software industry and explains what we all must do to raise the standards of quality throughout the technological world.
