Defining the Problem
As simple as todo lists are conceptually, there are numerous approaches, so I began this design exercise with a bit of research. People often have a tendency to struggle with not only logging too many tasks, but prioritization of tasks as well. Both of these issues can make it difficult for an individual to complete tasks in a timely fashion.
One approach that aims to solve both issues is the “1-3-5” list. It expects only that 9 tasks are to be completed, with 1 major task, 3 moderate tasks, and 5 small tasks. Writing tasks on paper is by far the simplest way to maintain a todo list, so I had to make sure my design would enhance this simplicity, rather than detract from it.
Productivity is a huge app category, but I did not find any that approached to-do lists using the 1-3-5 strategy. I began by reading some articles about this strategy on the web, writing my thoughts out on paper.
Writing allows me to move to sketching seamlessly. As I began to draw some concepts for the app, I tackled different approaches to the design, deciding that, while the 1-3-5 approach lends itself to a hierarchical design, simpler would be better.
