Every member must konw his specialization relative to what his other teammates can do best.A good organization is really needed in proper distribution of work.The best member of any group is he who demands work based on what he can do.When we are assigned to do or work on something,we must also know where to go for help (just in case we couldn't work out on something),and when help must be asked.Ultimately,it is every group member's responsibility to ensure that everyone has a job to do and that everyone is always the best man for his job.
