POSIWID: The Purpose Of A System Is What It Does Shirt

“The purpose of a system is what it does” (POSIWID) is an important concept in systems theory that has many applications in society and politics. Coined by British cybernetician Stafford Beer, the POSIWID principle points out that the true function of a system is ultimately revealed by its observable actions and outcomes, not by its intended or stated purpose. In other words, evaluate governance and policies based on their actual, tangible effects rather than their alleged goals.

How it's made

This unisex shirt is made with medium fabric (5.3 oz/yd² (180 g/m²)) consisting of 100% cotton for year-round comfort that is sustainable and highly durable. The classic fit of this shirt ensures a comfy, relaxed wear while the crew neckline adds that neat, timeless look that can blend into any occasion, casual or semi-formal.

The tear-away label means a scratch-free experience with no irritation or discomfort whatsoever. No side seams mean there are no itchy interruptions under the arms. The shoulders have tape for improved durability.

The cotton for the shirt is ethically grown and harvested, and the US Cotton Trust Protocol has ensured an ethical and sustainable production. The shirt is also certified by Oeko-Tex for safety and quality assurance.
