The ultimate goal of this field trial is to systematically evaluate a novel care coordination tool for children with Type 2 Diabetes (T2D) in an office setting at Emory/Childrens Healthcare of Atlanta. The Guide to Goals (GTG) application was designed and developed at Georgia Institute of Technology with the aim of providing evidence-based information in a timely manner to all the stakeholders involved in the care of a T2D patient during an office visit

The purpose of this project is to evaluate the user interface of GTG for ease-of-use. By observing and analyzing actual user experience with the current version of the app investigators aim to learn about its shortcomings. Findings from this phase will be used to make GTG more user friendly. GTG is aimed at the following user groups: 1. Patients/caretakers 2. Font-desk staff 3. Nurses 4. Certified Diabetes Educators 5. Physicians In this phase, two participants will be recruited from each of the five user groups for a one-hour usability testing session during which time they will be subjected to the following: A. Introduction to study team and session procedures with the help of a physical consent form (15 minutes) B. Perform a set of tasks on the GTG application (15 minutes) C. Post task interview with study team (15 minutes) D. Fill out post-interview questionnaire (15 minutes) The specific set of tasks that each participants will perform during the usability testing session will be:

1. Front Desk Staff: On the Provider Login Screen, log in using the username and password provided by the research team on the Patient Screen, add a new patient on the Edit Patient Screen, add the Diabetes Family Responsibility Questionnaire on the Edit Patient Screen, create a survey access code to share with the patient.
2. Patient and/or Family Member: On the Patient Login Screen, log in using the last name and session ID provided by the research team on the Surveys Screen, click on a pending survey when the survey opens, respond to the survey submit the survey log out of the Guide-Goals Application.
3. Nurse: On the Provider Login Screen, log in using the username and password provided by the research team on the Patients Screen, choose patient Will Owens on the Visit Status screen, change HbA1C value to 10% on the Visit Status screen, change Nephropathy evaluation to Abnormal log out of Guide to Goals application.
4. Certified Diabetes Educator: On the Provider Login Screen, log in using the participant's username and password provided by the research team on the Patients Screen, choose patient Will Owens on the Visit Status Screen, add comments needs to be followed up regarding ketosis education in the comments for provider text box on the Visit Status Screen, add a goal for the patient log out of Goals-to-Guide application.
5. Physician: On the Provider Login Screen, log in using the username and password provided by the research team on the Patients Screen, choose patient Will Owens on the Visit Status Screen review planning and accountability sections for errors on the Visit Status Screen, add a goal for the patient log out of Goals- to-Guide application.
