For example, a survey of decision makers and training managers of businesses with 100 to 1,000 employees, conducted by Kelton Research for Citrix Online, found that when traditional corporate training programs underachieve, logistical obstacles such as employee availability, time constraints and staffing are mostly to blame. Respondents cited frequent business travel and remote working as key reasons for low participation in training. In-person training remains effective when all participants are able to be in the same room, but that is not always the reality for many companies, especially for small and medium-sized businesses.
