Musings of a Marketing Maven

Yes­ter­day I was reminded that inter­faces, if untested for a crit­i­cal use case, can have poten­tially dis­as­trous consequences.

In this case the inter­face was between the rub­ber fric­tion pads at the bot­tom of a long exten­sion lad­der and the rain slick Trex sur­face of a deck. While clean­ing gut­ters vig­or­ously after a recent wind­storm, my hus­band must have put that inter­face under stress…

The lad­der slipped out from under him, and my hus­band fell two sto­ries from where he was rak­ing out the gut­ter. For­tu­nately, the top of the lad­der scraped along the wall before its bot­tom end crashed through the deck ban­is­ter. This slowed the momen­tum of Bruce’s fall, leav­ing him with seri­ous con­tu­sions instead of bro­ken bones (or even worse) when he recov­ered from the shock of hit­ting the deck.

Now he double-checks and backs up the inter­face before mount­ing the ladder.

A use­ful metaphor…
