Management of project and product teams

How does a traditional administrative organizational structure work? Each department is on its own: developers with developers, designers with designers, business separately.
In today’s world, everything works differently. The trend was set by IT with its now legendary Agile, which quickly went beyond the industry. Now everyone is trying to build a flexible organizational structure.

If a bank wants to launch a new product, it assembles a team with business representatives, designers, developers, testers, etc. Being on the same field, they can solve a common problem, understand each other’s problems and move towards the result together. It is impossible to create a department for every project – the unit of management becomes the end-to-end teams.
