It’s New Years again and time to take stock of things in our lives. As we know, the two rules of Personal Kanban are to Visualize Your Work and Limit Your Work-In-Progress (WIP).One of the most important factors in limiting or controlling our WIP is understanding our work - this includes appreciating our work, when we’ve completed it, and what we did to complete it.2014 has been a pretty tough year for me personally and when I look back on the last 12 months I tend to view it in my own pessimism bias.But Timehop, an app I have on my Galaxy Tab, keeps thwarting my pessimism and it’s doing it by confronting me with facts. Simply confronting me with what actually happened one, two, three, four, and five years ago. Timehop is an automated long-range Retrospective.Right now it is nearly exactly one year since I stood in my office in Seattle and drew the image above. See? That’s right now.If you would have asked me, I would have said that was at least two years ago. It’s significant because it means that those drawings led to the Modus Cooperandi Problem Solving System, about a dozen Lunch&Learns where we taught customers the process, and a great partnership with Riot Games to create a complete version of it.When we have sour notes, we tend to allow those notes to overwhelm our interpretation of the entire song. We can have one long very pleasant event and then something happens at the end and we say, “That just ruined the whole thing for me.” I was allowing this last year to be painted with a broad brush because I was focused on a few particularly painful episodes.Timehop, here, served as my visual control, sampling my social media past and showing me what I have actually been doing. What other visual controls are you employing beyond your Personal Kanban to keep track of the good work you’ve done?
