Vasya and Petya simultaneously started writing the same product.
Vasya was "result-oriented" and immediately began to write shit code without thinking about architecture.
And Petya developed the architecture for a month, a month made a convenient intuitive interface that would envy Johnny Ive, then a month wrote tests, then two months wrote the code itself and got the perfect stable application.
But Vasya released a month later the first version of the program, although not perfect, though with bugs, but working, and began to sell it. A month later released a second version correcting bugs of the first and adding new bugs. A month later, the revenue from sales hired two intelligent programmers, who in two months repaired the entire code, according to the wishes of users, doped the interface and released a third version of the program.
Overall, five months later, Vasai had two employees, a bunch of customers and a portable app that meets customer wishes.
Petty had a leased app unknown to anyone, a minus on the bank account and no customer.
In the conclusion of this fictional example, it can be said that six months later, Vasya bought all the work of Petty, took Petty into the staff as a tester, and himself fell into a drunk on his new Tuareg.
