And short attention spans are rampant today in the people we work with, employ, and unfortunately, ourselves. Here’s some of what I see happening today: Inability to tackle long-term problems — Short attention spans do not lend themselves to tackling long-term problems that can’t be easily solved. It’s more rewarding to drop anything difficult and move on to something that can be accomplished in 90 seconds, so people tend to do more of the latter and less of the former. Inability to finish projects — See above; same problem. Anything new and shiny that distracts you from your goal cannot be ignored, just like those Facebook notifications that someone “liked” the most recent photo of your cat or last night’s meal. Inability to focus in a meeting — Because people are so distracted checking their phones and computers for emails, text messages, and LinkedIn notifications, they can’t pay attention to the topic being discussed and, of course, miss a lot of important information that may actually affect how well they do their jobs. Miscommunications — Going to meet someone takes way too much effort. Phone calls PAY take too much effort — better to send a quick, terse email or text message. No reason that could be misinterpreted, right? Wrong! This is part of the reason people miscommunicate and don’t get along. attention! Inability to read anything — It takes too long to read a book or a newspaper. Better to get headlines in 60 seconds from a quick review of your Twitter feed or Facebook newsfeed. Short attention spans pose problems Of course, this can stunt your learning. for the engineering profession. I don’t think any of this short attention span stuff bodes well for the engineering profession nor our society as a whole. I don’t know what can stop it, but I am encouraged to see that it is starting to be more widely recognized as a problem that will, at some point, have to be addressed. Meanwhile, get outside and enjoy this summer. Don’t forget to use sunscreen! And for those of you who still have sufficient attention span to read — and learn — we have another great issue of Civil + Structural Engineer magazine for you to enjoy! And when you’re finished, please be sure to pass it on to someone else who might enjoy it. MARK C.

Historically, profits have been fairly low, but a few simple techniques can have a significant impact. Techniques to increase profitability include the following: QUARTERLY Specialize —While there is not always a direct correlation between specialization in a project type, anecdotal evidence notes that the learning OVERAGES? curve is reduced when repeat design work on similar project types occurs. Have good timesheet management — Today, very few firms use paper timesheets; nearly all use electronic timesheets, allowing for rapid and effective collection of time on a daily basis. CONTROL Prevent scope creep — Every firm should have a well-developed system for monitoring project scope of services. Have an effective project management system — While not a panacea, OVERAGES project profitability can be strongly affected by having an individual in charge of a project’s scope, schedule, and design budget. TODAY Recognize that higher chargeable rates do not always translate
