If you want to learn to ski permanently and safely, it is not enough to buy a book. You can't learn to run a marathon in three days with a running coach and it doesn't help to fast for five days once a year to live a healthier life. Everyone realises that.
Nevertheless, we behave in exactly the same way with our managers and teams. There is a problem in the team - we organise a one-day workshop.
The managers are supposed to learn how to communicate better or how to deal with difficult employees, then off they go on a three-day communication training course.
These measures are not only very costly and ineffective. In the worst case, they can even demotivate employees: ‘Now we've had the workshop and nothing changes!’; ‘It was so good in the training and it doesn't work in everyday life!’
As with the topics described above, PD and team measures only work in the long term. Theory, practice, application and feedback or reflection with a professional in their field. Like a sports coach or a companion on the path to behavioural adjustment. Personnel and team development is nothing else.
