Mishnah Kelim 17:2-3

Hook

You think you’re running a lean startup, but you’re likely holding onto "zombie assets"—features, products, or processes that no longer perform their primary function but linger because of legacy inertia.

Text Snapshot

The Mishnah discusses the threshold at which a vessel is considered "broken" or useless. Mishnah Kelim 17:2 notes: "A chamber-pot that cannot hold liquids but can still hold excrement remains unclean [i.e., still considered a vessel]." However, Rabban Gamaliel rules: "It is clean [no longer a vessel] since people do not usually keep one that is in such a condition."

Analysis

1. Function Defines Reality

The text teaches that an object is defined by its primary utility, not its original intent. If a tool loses its core competency (holding liquids), its secondary, grimy utility (holding waste) doesn't justify keeping it in the inventory. In business, if a feature no longer serves the customer’s main goal, stop pretending it adds value.

2. The Standard of "Ordinary Use"

Rabban Gamaliel argues that if a rational person wouldn’t keep a broken item, the organization shouldn't either. Don’t build internal policies or product roadmaps around edge cases or "junk drawer" behaviors. If the majority of users wouldn't tolerate the current state of a feature, it’s already dead.

3. The "Standardization" Trap

The Mishnah details various "moderate sizes" (pomegranates, olives, eggs) to define failure. This reminds us that you cannot manage what you do not measure. If you haven't defined the KPI that signals a feature is "broken," you’ll keep paying the maintenance tax on it indefinitely.

Policy Move

The "Zombie Audit": Every quarter, identify the bottom 10% of features by usage. If a feature is broken or underperforming, it is not "maintained"—it is deprecated. If it doesn't hold the "liquids" (core value), kill it, regardless of whether it still manages to "hold excrement" (marginal, low-value tasks).

Board-Level Question

"Are we maintaining this product because it serves our customer, or are we just afraid of the friction associated with deleting it?"

Takeaway

Don't be a curator of broken vessels. If it’s not performing its primary purpose, it’s not an asset—it’s a liability.
