The critical path to putting the team together

       It starts with the big boss, of course

       Next comes the customer. If you can’t get at least one customer on the team, there isn’t much point in going any further! That’s an essential part of the XP mind-set

       Once you have your customer, you need to have at least on experienced development coach and preferably one business coach. These coaches need to be experienced because they will have to defend XP throughout the development process

       Then you will need to add the developers and testers to the team. Remember that in order to communicate effectively, you need to keep your XP team small. So, select between four and twelve developers and two testers

       You can now select a tracker. The tracker role will be a part-time role and may be a person who is shared among two XP teams

       The SMEs or business analysts can be added as needed, but don’t forget to keep you team small. You can also bring in other experts as needed throughout the development process
