Ninety-Ninety Rule
A rule for tracking computer programming development time. The full statement of the rule is, "The first 90% of the code accounts for the first 90% of the development time. The remaining 10% of the code accounts for the other 90% of the development time." The rule simultaneously emphasizes two important points in software development. The first is that for almost any product, most of the development time will be used on relatively small but difficult sections of the code. The second is that the first point often leads to extremely optimistic project schedules. The ultimate lesson to learn from this rule is that the amount of the project that is completed is NOT tied to the amount of code completed, and that substituting one for the other can be disastrous. The ninety-ninety rule is often mistaken for a typo, with users assuming that the first 90% of code should correspond to the first 10% of time; while this is logically correct, it is NOT the original aphorism.
The Urban Dictionary Mug

I love it! Thanks! So
Great present for a retiring colleague with custom saying she's known for!

Loved this mug! So unique and you can edit the text to add something unique.
I gave it to my friend who took money from me and never returned.
I love the fact that I was able to customize my name since I've never been able to find anything with my name. The only downside is it's smaller than I thought it would be (I guess I didn't pay much attention to that), wish it was bigger, only about 10 oz total.
It's simply awesome; and plus, the word means a lot.
Really fast and looks great! Took a chance on Christmas gift and it was a success!
Awesome mug feels really nice good weight and color although I think the shade could be a little brighter when it comes to the highlighter yellow, I am still pleased with the outcome and the fact that a whole passage was so neatly printed onto the product, very pleased with the packaging too! That made it so easy to wrap just in time for Christmas. Who knew!!
okay so the mug was mid but when you have a genz meme and give it to one of the most serious people you know then it's pretty funny
Nice mug, great feel‼️
Perfect!
Good quality ceramic cup! Worth the novelty price!

Perfect gift for my gf
Looks great! Came quick
Gave it to my nerd brother. He used it consume liquid

Love it

as a fan of non-Z-generation-UD (since 2000 more or less) , especially of old-school definitions ("phat!") (as Nick, the more time passes by, the more I reach my inner age = 75 XD) , I totally appreciated the delivery in time for Christmas! (whispering) Perhaps printing quality in the Spain printing company is not as good as in the US, but - hey! - I got it before Christmas as a gift for my thank-God-non-Gen-Z-sister! ;) hugs from the eighties, and from Italy, and thanks!

This is SO cool. Morning coffee will always memorialize my new addition to the English lexicon.

Too inappropriate
Item came at appropriate time in good condition.
