This is how I rewrote everything, gave away two free cars, and saved thirty-two million dollars.
In week one, we look at the numbers. You are the new Chief Technology Officer. You have the corner office. You finally made it. The Vice President of Engineering closes the door. She tells you that you have a fifty million dollar technology budget. Forty million dollars, or eighty percent, goes to legacy maintenance. Two million dollars, which is four percent, goes to new products. You are spending eighty percent chasing the past while competitors invest one hundred percent in the future. She shows you Chen's pricing engine. It was built in twenty fifteen. It has fifty-two thousand lines of code. It costs five point eight million dollars annually to maintain. She warns you that whatever you do, do not propose a rewrite. They tried twice and both failed. You just inherited a forty million dollar time bomb.
In week two, you start the experiment. You open the new artificial intelligence coding tools. You feed the requirements for Chen's engine in. Eight minutes later, you have three thousand four hundred lines of working code. Four months of human work became six hours with artificial intelligence. You test it. It works for ninety-nine point four percent of cases. It misses edge cases like billionaires with Bitcoin collateral. The estimated annual cost is three hundred seventy-five thousand dollars versus five point eight million dollars. You do the math. That is a ninety-three point five percent cost reduction on one service.
Then comes the heresy. It is Friday at the leadership meeting. You tell them that Chen's code costs five point eight million dollars annually. You regenerated it with artificial intelligence for three hundred seventy-five thousand dollars. It handles ninety-nine point four percent of cases. The point six percent it misses, which is maybe fifty weird cases a year, you handle manually. The Vice President of Engineering asks about the edge cases. You tell her they cost fifteen thousand dollars annually in manual reviews versus five point eight million dollars in perfect automation. At the macro level, you will give away a free one hundred eighty thousand dollar car once a year if it means saving five point four million dollars.
The Chief Financial Officer is doing math. He asks how many services you can do this to. You tell him all of them. You have one point two million lines of legacy code consuming forty million dollars annually. You can regenerate the entire system as one hundred twenty thousand lines, which is ten percent of the original, for under eight million dollars annually. The Chief Executive Officer asks if you want to rewrite everything. You say you want to delete everything and regenerate it in ninety days. You want to free up thirty-two million dollars of the budget, or sixty-four percent, and move from quarterly releases to weekly.
The Chief Executive Officer asks what if things break. You tell him that then you handle them. You give white-glove service. If you accidentally approve a billionaire's weird loan, you make him a customer for life. If you mess up badly, you give away a car and call it marketing. That is still cheaper than spending forty million dollars maintaining perfection. He asks what you need. You say you need permission to burn the shrine and his backing when you give away two free cars.
During the ninety-day blitz, you do not ask permission twice. You move. In month one, the pricing engine went from fifty-two thousand lines to three thousand four hundred lines. The cost dropped from five point eight million dollars to three hundred seventy-five thousand dollars. Credit decisioning went from sixty-eight thousand lines to four thousand two hundred lines. The cost dropped from four point eight million dollars to three hundred twenty thousand dollars. Document generation went from forty-five thousand lines to two thousand eight hundred lines. The cost dropped from three point two million dollars to two hundred eighty thousand dollars.
In month two, eight more services were rewritten. Total code went from one point two million lines to one hundred eighty thousand lines, which is fifteen percent of the original. The release cycle moved from quarterly to weekly. Legacy cost dropped from forty million dollars to twelve million dollars.
In month three, four more services were finished. The final code was one hundred twenty thousand lines, or ten percent of the original. Legacy cost was eight million dollars. You freed thirty-two million dollars, which is sixty-four percent of the total technology budget. You encountered one hundred eighty-seven edge cases and handled them all manually. The cost was eight thousand five hundred dollars. The previous cost of perfect automation was twenty-six point four million dollars. You gave away two free cars at a cost of three hundred sixty thousand dollars. The public relations value was eight hundred thousand dollars. Customer referrals from those two cases brought in four hundred twenty thousand dollars in margin.
In week twelve, you see the results at the board presentation. The budget was reallocated. Before, eighty percent went to legacy maintenance and four percent went to new products. After, sixteen percent goes to legacy maintenance and sixty-eight percent goes to new products. You freed up thirty-two million dollars annually. The system was transformed. Code went from one point two million lines to one hundred twenty thousand lines, a ninety percent reduction. Releases went from four per year to fifty-two per year, which is thirteen times faster. The cost per release dropped from one point four five million dollars to seven thousand two hundred dollars, a ninety-nine point five percent reduction.
Consider the two free cars. The billionaire Bitcoin loan was auto-approved erroneously. You gave white-glove service. He referred eight customers worth three hundred forty thousand dollars. In a multi-state edge case, the system glitched. You gave the customer an exceptional experience and they became a case study in customer service. The total cost was three hundred sixty thousand dollars and the total value was one point two million dollars.
The Chief Executive Officer asks if you rewrote the entire system in ninety days. You tell him you did not rewrite it. You deleted ninety percent of it and regenerated ten percent with artificial intelligence. The code that took a decade to write took ninety days to regenerate. He asks about those free cars. You tell him it was the best money you ever spent. Those two customers are telling everyone you are the smoothest company they have ever worked with. That is better than perfect code.
A board member notes that previous Chief Technology Officers proposed three-year transformations while you did it in ninety days and asks how. You tell him that previous officers tried to preserve the shrine while you burned it. They spent forty million dollars maintaining one point two million lines to achieve one hundred percent perfection. You spend eight million dollars maintaining one hundred twenty thousand lines to achieve ninety-nine point four percent perfection and legendary service on the point six percent. They shipped quarterly because they were terrified of breaking things. You ship weekly because breaking things and fixing them fast is cheaper than perfection. At the macro level, giving away two one hundred eighty thousand dollar cars is cheaper than spending thirty-two million dollars on code that prevents you from ever giving away cars.
Six months later, your Vice President of Engineering speaks to you. She says that when you deleted Chen's code on day fifteen, she thought you were insane. When you gave away that first free car in month two, she thought you would be fired. But then she realized you understood something the other officers did not. The code was never the asset. Moving fast was the asset. And you could regenerate the code for ten percent of the space at twenty percent of the cost. Previous officers could not accept giving away a car. You understood that two free cars is cheaper than thirty-two million dollars in legacy maintenance. They worshipped perfection. You worshipped velocity.
Now, this is for you. Check your technology budget. If you are spending more than fifty percent on legacy maintenance, you are in danger. If you are spending more than seventy percent, you are in crisis. If you are spending eighty percent like we were, you are already losing.
Here is the play. Regenerate your entire system with artificial intelligence. Reduce it to ten percent of the original code. Accept that you will miss edge cases. Handle them with humans. If you mess up, give legendary service. If you really mess up, give away something and call it marketing. At the macro level, two free cars at three hundred sixty thousand dollars is cheaper than thirty-two million dollars in legacy maintenance.
In ninety days, you can rewrite everything to ten percent of the original size. You can free up sixty percent or more of your technology budget. You can ship thirteen times faster. You can accept imperfection. You can give away a couple of cars if needed. Your budget goes from eighty percent past and four percent future to sixteen percent past and sixty-eight percent future.
Your competitors are doing this now. The ones who move first will outspend you fifteen to one on new products. The window is twelve months. Maybe less. Will you preserve the shrine while competitors lap you? Or will you burn it, give away two cars, and invest sixty-eight percent in the future? Choose this week. Because your competitor's new Chief Technology Officer just did.
Ninety days. Thirty-two million dollars freed. Ninety percent less code. Two free cars. Thirteen times faster. Or watch competitors win while you maintain perfection.
