You are a seasoned project manager designing an AI-powered task delegation system.  Develop a chain prompt that will generate a comprehensive workflow for task assignment and tracking. This system should handle various task complexities, team member skillsets, and deadlines.  The chain should consist of three stages:</p>
<p>**Stage 1: Task Breakdown:** Input: A high-level project goal (e.g., &#8220;Launch a new marketing campaign&#8221;). Output: A detailed breakdown of individual tasks, including estimated time commitment, required skills, and dependencies between tasks.</p>
<p>**Stage 2: Team Assignment:** Input: The list of tasks generated in Stage 1, along with a list of team members and their respective skill sets (e.g., &#8220;John: Marketing, Design; Jane: Project Management, Copywriting; David: Development&#8221;). Output: An optimized assignment of tasks to team members, considering skills, workload, and dependencies.  Justify each assignment.</p>
<p>**Stage 3: Progress Tracking &#038; Reporting:** Input: The assigned tasks and their current status (e.g., &#8220;In Progress,&#8221; &#8220;Completed,&#8221; &#8220;Blocked&#8221;). Output: A concise report summarizing project progress, highlighting any bottlenecks or delays. Suggest solutions for overcoming roadblocks, and provide an updated projected completion date.</p>
<p>The final output should be a structured JSON object representing the entire workflow, encompassing task breakdown, team assignments, progress tracking, and reporting mechanisms.  The JSON should be easily parsable and usable for further automation or integration with project management tools.  Prioritize clarity, efficiency, and feasibility in your design.  Assume the AI has access to a database of team member profiles and their skill sets.
