However, there’s a line of thinking followed by both that’s not supported by further research showing that there is no such thing as a one-size-fits-all solution to task management. People appear to get by using all sorts of different tools.
But there is a reason to their madness… people upgrade their methods when they start to experience unwanted symptoms. They only stop when they find a solution that works, but it’s a random search for most people.
However, my research shows that there IS a pattern to their choices. I explain that there is a hierarchy of methods to be used for everything from a handful of tasks to hundreds of tasks. It’s just that we need to keep changing our methods as long as we increase the number of tasks we are trying to manage.
Here’s the article. Hope it helps.
