2. Write a memo to your instructor in which you describe a communication you wrote that was useful and persuasive because you had defined its goals along the lines described in this chapter. Explain the features of your communica- tion that were effective because of your thinking about the communication from the perspective of your reader. Alternatively, think of a communication you wrote that was not as useful or persuasive as you had hoped because you had not thought about it from your read- er's perspective. Tell how you would write it differently now-and why.
