The Beatles is a symbol of the success of four great individuals. Lennon, McCartney, Harrison and Starr formed a thriving and successful group. Thanks to excellent cooperation, they appeared together as a team. It turns out that the rules of The Beatles can serve as inspiration for managers who want to lead a harmonious and successful team.
By the time the first song by The Beatles reached the top of the British charts, the band had already spent thousands of hours getting to know each other and working together.
So it's worth taking the time to get to know each other's team members and reach out on common, simpler tasks - before they have to work together on really important projects. Many managers forget that in order for the team to function effectively, they need time to integrate. In my opinion, this mistake is often made at the beginning of projects carried out using the Agile method, which is so popular today, and with various variations of this type of activity (eg Design Thinking).
