Klein also noticed that performance improvement is driven by increasing insights, but few organizations go about this in an applied manner. I have noted that three types of insights that Klein observed through his 120 cases, can be developed through PKM – connections, coincidences and curiosity. Personal knowledge mastery can help to improve insights through increased connections, enhance the potential for coincidences, and develop a discipline of curiosity. The best professionals in the network era are those who are open to new insights, and not just focused on reducing errors.
