Another view of negotiation comprises four elements: "strategy", "process", "tools", and "tactics". Strategy comprises the top level goals – typically including relationship and the final outcome. Processes and tools include the steps to follow and roles to take in preparing for and negotiating with the other parties. Tactics include more detailed statements and actions and responses to others' statements and actions. Some add to this "persuasion and influence", asserting that these have become integral to modern day negotiation success, and so should not be omitted.
