MEASURE!!
Who knows what that is?
It’s the Fifa World Cup Trophy
Teams are currently competing in the qualifications to compete in Brazil 2014
This is “my” austrian national team soccer team.
Their GOAL is to qualify for Brazil 2014. After the many failed attempts in the past we hired a new coach who’s goal is to form a new team that PERFORMs good enough to qualify
In order to get there the team competed in many test games. Which gaves them a lot of confidence because they played against teams that were “easier” to beat.
At the end of these tests we even started in the qualification with some wins against teams that we were expecting to win
So – at the end of these “test and easy qualification games” we thought: “ALL GOOD – THE ROAD IS OPEN FOR 2014 – NOT ONLY WILL WE QUALIFY BUT WE ALSO BELIEVE WE HAVE SUCH A STRONG TEAM THAT WILL ALSO DO WELL AT THE WORLDCUP”
Then reality kicked in when we had our first “real competitor” – it was the first qualification against a team whos quality level is at a level that we have to expect at the world cup.
The competing team was Germany – and – based on these images you can see how the game went
The coach is responsible to watch the game and see how things are going.
Like in other sports – soccer has a couple of Key Performance Indicators such as Ball Possession, Fouls and the actual score
The first 5 minutes actually didn’t look too bad
After the first 5 minutes the game changes – with germany taking over the game in their typical way. The KPIs make this very clear
The coach is responsible to react based on these values and how the game wents
The coach should use more data for detailed analysis on what is going wrong in the game
One of his options is to substitute players – or even change tactics
Does this succeed based on the KPIs that we have seen before?
Well – not always. Just replacing players – putting some in that are faster in chasing the ball doesn’t always help
