Industrial Safety 的迷思

破解迷思

Dr. Sidney Dekker

(one of the) characteristic of complex systems: doing the same thing twice will not predictably or necessarily lead to the same result

4 coditions to make complex system safer

• Complex work is managed so that problems in design and operations are revealed
• Problems are swarmed and solved, resulting in quick construction of new knowledge
• New local knowledge ix exploited globally throughout the organization
• Leaders create other leaders who continually grow thess types of capabilities

Quality Control 左移

Ineffective Quality Control

• Requiring another team to complete tedious, error-prone, and manual tasks that could be easily automated and run as needed by the team
  who needs the work performed
• Requiring approvals from busy people who are distant from the work, forcing them to make decisions without an adequate knowledge of the
  work or the potential implications, or to merely rubber stamp their
  approvals
• Creating large volumes of documentation of questionable detail which become obsolete shortly after they are written
• Pushing large batches of work to teams and special committees for approval and processing and then waiting for responses

2 types of customer

• external customer
• internal customer
