Final answer:
Instant messaging and text messages are the forms of writing a manager can use to transmit information almost as quickly as a spoken message. Emails are more formal and require proper structure and proofreading, while instant messaging and text messaging allow for quick and efficient communication.
Step-by-step explanation:
A manager looking to both create and transmit information to others quickly, in a fashion comparable to a spoken message, can use various forms of writing. The options provided include Email, Instant messaging, Memo, and Text message. Considering the need for immediacy and the typical conventions of workplace communication, both instant messaging and text messages are the most suited formats for quick information transmission akin to verbal conversation.
Considering professional settings, emails should be used for formal and well-considered messages, following proper etiquette like standard spelling, punctuation, capitalization, and proofreading for clarity. However, for brief and immediate exchanges, where the message content is clear without additional context provided by facial expressions or tone of voice, instant messaging, and text messages are more convenient and efficient.
