The ODE app (web, IOS, Android) is designed to improve decision-making skills, for use with the ODE program or as a standalone tool. The ODE app is a cutting-edge tool designed to empower individuals to master the art of decision-making. With its user-friendly interface and plethora of resources and exercises, the app equips users with the skills of self-awareness, self-determination, and resilience. The app guides users through a step-by-step decision-making process, starting with defining one question at a time. Users begin by crafting one question they want to address with their decision. They then brainstorm criteria that are relevant to their decision, which can be evaluated using a choice between two options, a sliding scale, choices, or a numerical value. The criteria and options are entered by the user, not pre-entered, to foster ownership and responsibility. As users identify the criteria, they group them into related categories to make it easier to prioritize them. They then assign priorities to each group of criteria to determine which factors are most critical to their decision. Next, users add options to consider for their decision, which they can choose themselves. Users then assign values to each criterion for each option, using the feedback loop to gather input from family and friends. The app then generates a visual representation of the results, which users can review and adjust as needed. Users can play with different priorities and see how it affects the final decision. The process can be iterated on, with users going back to add more criteria or gather more information as needed. The ODE app does not provide a pre-entered list to choose from, the tool collects the data that is entered by the user. This promotes ownership and responsibility of the decision-making process. The app is suitable for young adults 14 years and older, providing a valuable tool for anyone who wants to improve their decision-making skills and prepare for their future.
