I think you have to have a clear idea of the way you want to play and the way for example in 2009 how I felt we needed to be playing to beat South Africa that became a conversation amongst the coaches where you do evolve it but before we met the players, we had a tactical plan. We wanted to develop because one of the things I wanted to do was develop how to play in the test matches from day one. So we didn't prepare for the individual provinces. We were looking at our own game that had to be out on the field by the time we played the first test. So everything was about getting a game towards that point and every time you put a line inside out you have a different group of players going out and putting Alliance Jersey on but what you had is your Tactical progression had to be through everybody and that I think is important and that then evolves with the players and how they come together that you are then is something that you molding and moving but you have to have certain principles of what you want to do that you keep coming back to so that everybody understands what you're trying to do and the sort of game you're trying to play and why and we had certain principles. We talked about Force Defender principle of how we wanted to get to a certain area. And then what we did once we were there but every player had to understand that so when you'd want a quick ball in a rock, you knew that two three passes out here was where you were expecting the next. Play to be planning a line campaign. I think is is different to planning for a school and or a club in a pre-season simply because you have a huge amount of talent there, but you still want to do drills and things that push the skills and you have a time constraint that you have to deliver a game within five weeks and everybody's got to be comfortable with that. But I think some of the process is exactly the same you want the players come coming together. You want them to enjoy their training but you want to understand the outcomes that you need from each session and then you need the understanding of the progression you're trying to make in how the group comes together.
