Use ～ようにする when you want to say you will make a conscious effort, or set up a practice/rule, to bring about a certain behaviour — as opposed to ～ようになる, which reports a change that happens on its own. In business writing and speech it is the standard way to commit to a course of action (～ようにします) or to request one politely (～ようにしてください) without sounding like a bare promise or order. The ～ている form (～ようにしている) expresses an ongoing policy or habit, which is useful for describing team practice in reports and interviews.
