From the outside we can only judge by the results we see. As an executive coach I find it interesting to speculate about what Lee’s leadership profile might be. I’ve worked with a lot of executives who absolutely do multitask and work on many different priorities at once and manage that effectively. I’ve also worked with those who struggle to effectively allocate their time to the longer term work.
Steven Covey came up with the model of categorizing tasks by high or low urgency (the degree to which environmental factors pressure you to work on them - e.g., deadlines, email or other reminders, pressure from other people) and high or low importance. Most people are pretty good at ignoring things that are low importance / low urgency (e.g., reorganizing my toolbox). And most people are good at working on things that are high importance / high urgency (e.g., responding to the fire alarm).
Where a lot of people struggle is that the rest of their time they easily slip into working on low importance / high urgency stuff. These are the things that are easy and obvious and give a sense of accomplishment (e.g., responding to emails, chatting with people around the office). They tend to neglect the high importance / low urgency (e.g., that big important thing that could get done now or in a month or six).
It’s possible that Lee manages these things well and the delays have nothing to do with him. But the results - and the Martínez extension - kind of smack of a guy who struggles to push high importance / low urgency to the top of his to do list.
