For example, an investor gives 100 thousand rubles. Then two people work together 3 month (share), then they are joined by another (a fraction), and they have three of them working for another 3 months. Then the first loses faith in the project and leaves, the remaining two continue to operate for another three months and finally releases the project.
All people have different value on the labour market. That is, their time is not equal.
After the departure of the first person (the programmer), the team decided to give up half of his work, because it is easier to rewrite part of the code from scratch to finish all of his work.
The first month generally idle, because they chose the wrong architecture, had to send all the work done in the basket. But provided valuable experience. In a sense, this is also a contribution, although a personal experience.
The idea belongs to the first. But without the emotional support from the second, the first would not be able to think through and execute.
The project generates income every month (different). Of the remaining people, one very lazy and just wants to get the money. The other continues to work to develop the project, promotes. And after 3 months joined another man, also in proportion, but it works on the floor of force in the evenings (after regular work elsewhere).
Use 1 hour different people have different. Sometimes even a negative benefit, when a solution leads to a decrease in profit next month.
How in this hell not to go crazy and allocate the money as fair
, make everybody happy? Including everyone who wanted a share of the project and was concerned with: the money or your time - Deposit. In the example is 5 people: the investor plus 4 co-author.
How better to issue in the form of a contract?
The point is to share considered depending on the contribution. Because if the share is considered to be in the beginning and does not change, then there is no incentive to make the effort to try to do better, to work in good faith, to take the initiative in solving and preventing problems and bugs.
