Donella H. Meadows's book is brilliant. Not only does it apply to the worlds of climate change and ecology, but it will also apply to business, politics, and many spheres of activity. Read the book. Study it. link.amazon/B0eKQwD7B www.goodreads.com/re... #bookreviews #bookrecommendations
A framed display of the book cover “Thinking in Systems” by Donella H. Meadows stands on a wooden surface beside a potted cactus and two green notebooks, with a colorful spiral graphic on the cover. Text at the bottom reads “Review by Rajiv Chopra” and “www.rajivchopra.com”; the top also shows “Thinking in Systems” and “Donella H. Meadows.”

I don't think I am the only person who is wondering if they are using the Five Whys or Ishikawa Diagrams, or another technique, to find the cause of the technical faults.

Deming’s 14 points for Management already mentioned in 1982 psychological safety! 8. Drive out fear No one can put in their best performance unless they feel secure. “Se” is Latin for “without”. “Cure” means fear. “Secure”: without fear, not afraid to express ideas, to ask questions.

Computer scientist Margaret Hamilton coined the term “software engineer.” She directed the Software Engineering Division at MIT’s Instrumentation Lab & led development of the on-board flight software for NASA’s Apollo Guidance Computer. She was born #OTD in 1936 & turns 90 today! #WomenInSTEM
Two side-by-side black-and-white photographs of pioneering computer scientist Margaret Hamilton (born August 17, 1936). The left panel features a mature, close-up portrait where Hamilton gazes directly at the viewer with a serene, confident, and reflective expression, framed by her long, dark, slightly silvering hair. The right panel is a famous archival photograph showing a younger Hamilton standing indoors next to a towering stack of bound paper binders containing the Apollo Guidance Computer source code, which she led the development of at MIT. She is smiling broadly and wears a striped, long-sleeved mini dress with dark Mary Jane shoes and glasses, resting her hand proudly on top of the massive column of printed code. The overall composition contrasts her youthful triumph with her enduring legacy, capturing an optimistic, intellectually rigorous mood that highlights her monumental contributions to space exploration.
