Re: Point #2 is an important one
@sachinEE: I agree. Conducting tests would guarantee the skill level of employees on the increase. Another kind of practise could be out-house practise. It generally works out well when managed and judged by a member of the management. The thing is, to understand teamwork better, rouge team-members are paired with team playing members into achieving a real life physical project, game-style. The excercises can be varied. I've seen one relay race between two teams, the only thing is, there is no baton. The relay race uses humans to be carried off by their team members, and there the employee is the baton. That needs teamwork, and their learned practices can come in handy while dealing with project issues inside the company.
