Joanna and David are managers at a technology firm. They typically communicate with clients and employees via email. After receiving a message from him, Joanna suggests that David spend more time evaluating his emails before sending them. "There are a lot of problems in your most recent message," she says. "You use a lot of passive voice in your writing and rarely make concise points. Your emails are so wordy that I am often unable to figure out precisely what you mean. I even see simple spelling errors! If you took some more time to systematically proofread your emails, they wouldn't have these problems." David is unconvinced. "I use email for communicating quickly and efficiently," he argues. "Even though it's not concisely worded and has some misspellings, my writing still makes sense to the reader. Modern technology doesn't make our work any more efficient if we have to spend more time than ever doing pointless proofreading."
