Quality = version control: never perfect but always better
• Sharing will generate feed-back: version control becomes inevitable• update your own work• allow altered copies to proliferate
• Version control is common practice for• ISO 9001: doc, xls, pdf• Toyota Kaizen: keep on improving• Software engineering: windows update• … science is lacking behind anyway
