Based on what you learn from your prototype, organize a development strategy to methodically **program and style your solution** with efficiency and quality. Also prepare for the promotion and launch of your solution, and conduct unit testing to ensure all is in working order before an in-class demonstration. Many of the tasks for this stage may occur in parallel with occasional starts and stops appropriate for your development progress. | Task | Estimated Time | | -------------------------------------------- | -------------- | | Question Bank Development | 3 hours | | Interface Mockups | 2 hours | | Interactive Prototype | 1 hour | | Prototype Evaluation | 1 hour | | Code Development Outline & Begin Coding | 6 hours | | Marketing Card | 1 hour | | Code Testing | 2 hours | | Prepare Development Review and Demonstration | 2 hours | --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
