Well a couple of days ago I got my Boston Marathon bib number. The training to run for it is taking all the time I might otherwise be devoting to getting this website up and running more effectively. The lesson is on trade-offs. Which is going to reap the most value in the short and long term as an investment? The same trade off applies in organization design work – are we designing for the short term or with an eye to the future? The common way is to do both – the difficulty then lies in doing both well. That's where I like concepts of 'good enough'.
