An important takeaway from the book I got was that distilled checklists didn't work alone. It took some flexibility within the environment using the checklist to allow for its full potency, such as nurses being allowed to second-guess a doctor without fear of reprisals. In the tech industry I think we can apply the construction company example more appropriately, which was construction companies structuring themselves over the decades for an immediate rescheduling of work and inspections to meet a construction sequence when something came up. To be blunt and cynical, I don't believe that today's software management styles and scheduling are realistic in that manner. Whatever calendar flexibility exists is covered in name only. So I feel that too often project management decisions serve the calendar instead of allowing field hands to push back on launch dates.
