How has the organizational structure changed from start-up companies to large companies?

In the initial stage, the purpose is to quickly test the business model, so the tacit understanding between teams is good, the trust is good, the rules are simple, and team members must be comprehensive and able to fight in their respective fields. So the early architecture was simple and clear. In the development stage, business processes need to be standardized to reduce business costs and improve business development efficiency. In order to reasonably allocate business lines and formulate appropriate rules to ensure business development, it is necessary to clearly express the division of labor, business boundaries, expectations of new members, etc., so as to ensure that new employees can quickly understand and be familiar with business operations. In the development stage, the structure needs to be clear and reasonable, and members at all levels should establish mutual assistance, superior-subordinate help, business reporting and learning relationships. The goal of the stable phase is business separation and new business development, which requires both persistence and progress. Therefore, there will be two directions in the organizational structure, taking into account the interests distribution on the stable business line and the spirit and reward of new business development. At this time, the architecture will slightly test the wisdom of human resource allocation.
