Business writing is a much-studied area of corporate training and has the opportunity to enhance the organization's capabilities in a variety of ways. Previous research demonstrated post-training improvements in time spent on emails, better understanding by readers, and decreased costs associated with emails. This study evaluated a 1-hour business writing training workshop's impact on the organization using multiple perspectives, a sample writing analysis, and follow-up measurements to identify improvements. The purpose was to understand how the training changed the participants' email writing practices. Following the training, participants and their supervisors were pleased with the design and improved email effectiveness resulted. Introduction Background Over the last ten years, many studies explored email communications training effectiveness. Most of these studies focused on performance improvements with key themes related to: (a) decreased time spent on emails (Burgess, Jackson, & Edwards, 2004; Huang, Lin, & Lin, 2011; Moore & Moore, 2004; Soucek & Mouser, 2010), (b) better use of subject lines (Burgess, Jackson, & Edwards, 2004; Jackson & Culjak, 2006), (c) decreased message misunderstandings (Aguilar-Roca, William, Warrior, & O'Doud, 2009; Huang, Lin, & Lin, 2001; Jackson & Culjack, 2006; Moore & Moore, 2004), and (d) decreased costs associated with email use (Burgess, Jackson, & Edwards, 2004; Jackson & Culjack, 2006). The training themes in these studies included: (a) use of subject lines, (b) time management when dealing with emails, (c) formatting emails, and (d) writing for clarity. While some researchers found training participants did not take the class and subsequent skill assessment seriously (Pittenger, Miller, & Allison, 2006), others found that participants experienced increased perceptions of emailing abilities (Huang, Lin, & Lin, 2011), improved grammar, spelling and punctuation (Hof & Ashworth, 2010), and faster replies to emails (Huang, Lin, & Lin, 2011; Moore & Moore, 2004; Soucek & Moser, 2010). Combined, these effects produced better-written emails that were both clearer and more succinct, which reduced the overall financial impact on organizations who delivered such training. In this study, instructional designers created the Business Writing 101 Workshop to address a significant organizational business need – the need to write clear and concise emails to customers. Feedback from customers prompted senior leaders to seek out a learning solution in order to improve customer relations. The training development, delivery, and evaluation used these identified themes from the literature with the intent to achieve a positive return on investment for the organization. The training course was a one-hour, instructor-led course attended by 15-30 participants at a time. Each participant received a learning journal to take notes as he or she followed the facilitator's PowerPoint presentation. The presentation focused on the importance of a well-written email. Facilitators used dialogue and real-life examples to explore topics such as email structure, sentence structure, using words for maximum effect, positive versus negative tone, active versus passive verbs, avoiding jargon use, and proper spelling, punctuation, and capitalization. Facilitators showed participants how a G.R.E.A.T.
