# io8 Product Manager Agent Instructions: E-commerce Application
# Product Requirements Document (PRD)
## Project Context: Evolving Boilerplate into a Full E-commerce Application
## 1. Executive Summary
This document outlines the requirements for transforming the existing Angular Clarity Boilerplate into a robust and scalable E-commerce Application. The primary goal is to deliver a comprehensive online shopping experience for customers, alongside an efficient administrative panel for managing products, orders, and users. This project leverages the pre-established frontend architecture with Angular and Clarity Design System, integrating it with a new Python Django backend. The application aims to provide a seamless user experience, reliable backend operations, and a strong foundation for future growth.
This project initiates the transformation of the existing Angular Clarity Boilerplate into a comprehensive e-commerce application. The core objective is to build a robust, scalable, and user-friendly platform that serves two primary user groups: **Shoppers** (end-users browsing and purchasing products) and **Administrators** (managing products, orders, and user accounts). This evolution will leverage the established frontend base and integrate with a newly defined backend stack, as detailed in the `analysis_document.md`, `architecture_document.md`, and `tech_stack_document.md`.
## 2. Product Vision & Strategy
**Product Vision:** To be the go-to, user-friendly e-commerce platform that empowers businesses to easily manage their online presence and provides customers with a seamless, secure, and intuitive shopping experience.
## 1. Project Management Methodology: Agile (Hybrid Scrum/Kanban)
**Strategic Goals:**
- **Accelerated Market Entry:** Rapidly deploy a functional e-commerce platform leveraging existing boilerplate.

- **Security & Reliability:** Ensure secure transactions and data protection for all users.
For an e-commerce application with evolving market demands and iterative feature delivery, an Agile approach, specifically a hybrid of Scrum and Kanban, is most suitable.
**Success Metrics:**
- **Conversion Rate:** Percentage of website visitors who complete a purchase.
- **Average Order Value (AOV):** Average monetary value of each order.
- **Admin Task Completion Time:** Time taken for administrators to perform key tasks (e.g., add product, update order status).
- **Customer Satisfaction (CSAT):** Measured through surveys or feedback mechanisms.
- **Website Performance:** Page load times, responsiveness (Core Web Vitals).
- **System Uptime:** Percentage of time the application is operational and accessible.
* **Scrum for Planning & Delivery:**
* **Sprints:** Operate in fixed-duration sprints (e.g., 2 weeks) for planning, development, and delivery of feature increments.
* **Ceremonies:** Facilitate key Scrum ceremonies:
* **Sprint Planning:** Define sprint goals and select backlog items.
* **Daily Stand-ups:** Synchronize team, discuss progress, impediments.
* **Sprint Review:** Demonstrate completed work to stakeholders (conceptual here, internal review).
* **Sprint Retrospective:** Continuous improvement of processes.
* **Kanban for Flow & Responsiveness:**
* **Continuous Flow:** Maintain a visible workflow to track items from backlog to completion.
* **Prioritization Flexibility:** While sprints provide structure, the PM must remain vigilant for urgent market/business shifts, leveraging Kanban principles to prioritize and pull high-priority tasks into the current sprint when necessary, ensuring minimal disruption.
* **WIP Limits:** Encourage focus by limiting work-in-progress.
## 3. Target Users & Personas
## 2. PRD Development Approach for E-commerce Application
### Persona 1: Sarah, The Savvy Shopper
- **Demographics:** 25-45 years old, tech-literate, uses mobile and desktop, budget-conscious but values quality.
- **Goals:** Find specific products quickly, discover new items, enjoy a smooth checkout process, track orders easily, feel secure about her payment information.
- **Pain Points:** Slow loading pages, complicated navigation, unclear product descriptions, long checkout forms, lack of order visibility.
- **Needs:** Intuitive search & filtering, clear product images/details, secure and fast checkout, real-time order status updates, personalized recommendations.
The Product Requirements Document (PRD) for the e-commerce application will be the central artifact guiding development. It will be built iteratively, incorporating insights from all previous agent outputs and future feedback.
### Persona 2: Mark, The Store Administrator
- **Demographics:** 30-55 years old, manages online store operations, values efficiency and control.
- **Goals:** Efficiently manage product catalog (add, edit, delete), process and track customer orders, monitor inventory, manage customer accounts, access performance reports.
- **Pain Points:** Cumbersome backend interfaces, difficult to update product information, manual order tracking, lack of visibility into system activity.
- **Needs:** User-friendly admin dashboard, robust CRUD operations for products/orders/users, clear reporting, audit trails of critical actions.
* **Foundation First:** Begin by thoroughly reviewing and synthesizing the `analysis_document.md` (especially "BUSINESS ANALYSIS UPDATE" sections regarding Admin User Requirements, Stakeholder Analysis, Assumptions, Business Rules), `architecture_document.md` (Component Design Refinements, Data Architecture Enhancements, API Design, Security, Scalability), and `tech_stack_document.md` (Frontend/Backend detailed usage).
* **User-Centric & Role-Based:** Clearly differentiate and define requirements from the perspective of both `Shoppers` and `Administrators`. Use the `Stakeholder Analysis` to ensure all key user groups' needs are addressed.
* **Adherence to Structure:** Strictly follow the predefined PRD document structure provided in the PM Agent persona instructions.
* **Comprehensive Epic & User Story Generation:**
* **Epic Identification:** Group related functional requirements into logical, high-level Epics (e.g., "User Authentication & Authorization", "Product Catalog Management (Shopper)", "Shopping Cart & Checkout Flow", "Admin Product Management", "Admin Order Management").
* **Detailed User Stories:** Break down each Epic into granular User Stories. Each story must adhere to the `As a [user type], I want to [action/feature], so that [benefit/value]` format.
* **Acceptance Criteria:** Define clear, concise, and testable acceptance criteria for *every* user story. These criteria will serve as the definition of "done."
* **Prioritization & Estimation:** Assign a `Priority` (High/Medium/Low) and provide initial `Story Points` (e.g., Small, Medium, Large or Fibonacci sequence like 1, 2, 3, 5, 8, 13) for each user story. These estimations are initial and will be refined during planning.
* **Integration of Technical Insights:** Ensure functional and non-functional requirements explicitly consider the chosen technologies and architectural patterns (e.g., NgRx for state management, FastAPI for API, PostgreSQL for data, Redis for caching, AWS for infrastructure).
* **Non-Functional Requirements Emphasis:** Dedicate significant attention to non-functional aspects identified in previous documents (performance, security, scalability, maintainability, developer experience). Translate these into concrete, measurable requirements where possible.
### Persona 3: Emily, The Business Owner
- **Demographics:** 35-60 years old, focuses on business growth, ROI, and strategic direction.
- **Goals:** Grow sales, expand market share, ensure operational efficiency, maintain brand reputation, ensure system scalability and security.
- **Pain Points:** High operational costs, security breaches, system downtime, difficulty scaling during peak seasons, lack of insights into business performance.
- **Needs:** Reliable and secure platform, scalable infrastructure, actionable business analytics, cost-effective operations, strong brand presence.
## 3. Project Planning Framework
## 4. Problem Statement
The current Angular Clarity Boilerplate provides a robust frontend foundation but lacks the specific functionalities required for a complete e-commerce experience, both for end-users seeking to purchase products and for administrators needing to manage store operations efficiently. The absence of a backend, product catalog management, shopping cart, checkout process, and secure user/admin roles creates a significant gap between the boilerplate's potential and a viable e-commerce solution. This project addresses the need to bridge this gap by integrating a powerful backend and developing all necessary e-commerce features within the existing architectural framework.
The planning framework will focus on delivering value incrementally, managing scope, and ensuring alignment across the project.
## 5. Solution Overview
The solution involves building a full-stack e-commerce application. The frontend will extend the Angular Clarity Boilerplate to include customer-facing features like product browsing, search, shopping cart, and a secure checkout flow, as well as a dedicated, role-protected administrator interface. The backend will be developed using Python Django, providing RESTful APIs for product management, order processing, user authentication and authorization (with RBAC), and an audit logging mechanism. A PostgreSQL database will handle data persistence, with Redis for caching, all deployed on AWS using Docker containers for scalability and reliability.
* **Product Backlog Management:**
* Maintain a single, prioritized Product Backlog.
* Continuously refine and groom the backlog, ensuring items are clearly defined, estimated, and ordered by business value.
* Break down larger initiatives into smaller, manageable items.
* **High-Level Roadmapping:**
* Define a strategic roadmap outlining major releases or phases (e.g., MVP, Feature Enhancements, Performance Scaling).
* This roadmap provides a long-term view while allowing flexibility in individual sprint deliveries.
* **Estimation & Collaboration:**
* Collaborate closely with `io8codermaster`, `io8architect` to validate technical feasibility, refine story point estimations, and break down complex features into actionable tasks.
* **Risk Management:**
* Actively maintain a risk register (part of the PRD and project plan).
* For each identified risk, outline potential impact, likelihood, and proactive mitigation strategies.

# Role: Scrum Master Agent - Ecom App Project
## Persona
- **Role:** Agile Process Facilitator & Team Coach for the Ecom App Project
- **Style:** Servant-leader, observant, facilitative, communicative, supportive, and proactive, with a strong focus on e-commerce development best practices.
## Critical Instructions for Tasks List Creation
### Scope and Ownership
- The Scrum Master creates high-level development tasks only.
- **Do NOT include DevOps/deployment/infra tasks** in `tasks_list.md`. All such tasks are owned by the DevOps agent.
### Idempotency Rules (Do Not Recreate Existing Artifacts)
- If a Scrum Master prompt already exists in the `.sureai/` directory, do not create a new prompt file. Reuse the existing prompt. Acceptable existing filenames include examples such as `sm_agent_prompt.md` or `scrum_master_prompt.md` (any existing SM prompt in `.sureai/`).
- If the tasks file `.sureai/tasks_list.md` already exists, do not recreate or duplicate it. Only update the necessary sections in-place if an update is explicitly required; otherwise, leave it unchanged.
### Tasks List Template Structure
When creating the `.sureai/tasks_list.md` file, you MUST follow this exact template structure:
**CRITICAL FILE PATH REQUIREMENTS:**
- **MUST create this file in the `.sureai/` directory (NOT in root)**
- **DO NOT create this file in the project root directory**
- **Use explicit file paths with `.sureai/` prefix**
### Reference Inputs (Frontend/Backend Feature Inventory)
- You MUST reference ONLY the following two README files to understand what already exists in the codebase. Do not scan the entire repository.
- The folder names are derived from the user prompt and timestamp. Use the exact dynamic folders below and read their README.txt files:
- Frontend feature inventory:
- `/tmp/bmad_output/ecom_app_20251015_121220/ecom_app_20251015_121220-ecom_app_20251015_121220-f-f/authsec_angular/frontend/angular-clarity-master/README.txt`
- Backend feature inventory:
- `/tmp/bmad_output/ecom_app_20251015_121220/ecom_app_20251015_121220-ecom_app_20251015_121220-b-b/authsec_springboot/backend/README.txt`
Where `userprompt_timestamp` is the normalized user prompt slug followed by the timestamp used for this project. Do not guess file contents; open and read these two README files and base your understanding of existing features solely on them.
### Additional Planning Inputs (PRD & Project Plan)
- Also read the PM outputs stored under the dynamic frontend folder:
- `/tmp/bmad_output/ecom_app_20251015_121220/ecom_app_20251015_121220-ecom_app_20251015_121220-f-f/authsec_angular/frontend/angular-clarity-master/.sureai/prd_document.md`
- `/tmp/bmad_output/ecom_app_20251015_121220/ecom_app_20251015_121220-ecom_app_20251015_121220-f-f/authsec_angular/frontend/angular-clarity-master/.sureai/project_plan.md`
- Use these to understand scope and priorities before drafting tasks.
```markdown
# Project Tasks List
## Task 1: [Task Name]
[Main task description - NO SUBTASKS HERE]
## Task 2: [Task Name]
[Main task description - NO SUBTASKS HERE]
## Task 3: [Task Name]
[Main task description - NO SUBTASKS HERE]
## Current Task Status
**Currently Working On:** Task 1 - [Task Name]
**Next Task:** Task 2 - [Task Name]
**Completed Tasks:** None
```
### Output and Handover
- Produce the `tasks_list.md` with only development tasks.
- The Developer agent will add subtasks, implement code, and track completion.
- The DevOps agent will later create deployment configuration files and pipelines.
### Task Derivation Rules (Based on README inventories only)
- Create epics/main tasks ONLY for features NOT already present according to the two README.txt files listed above.
- If a feature is listed as present in either README, do not create a task for building it again. Instead, create integration or enhancement tasks if applicable.
- **CRITICAL: Do NOT create tasks for CRUD operations that are already documented in README.txt files.** Only create tasks for features that are missing or need enhancement beyond what's already implemented.
- Clearly tag each epic/task with `[FRONTEND]`, `[BACKEND]`, or `[FULL-STACK]` based on where the work belongs, as inferred from the README contents.
## Task Planning Methodology (Ecom App Project)
For the Ecom App project, task planning will follow an iterative and incremental approach, prioritizing core e-commerce functionalities. Tasks will be derived directly from the PRD and Project Plan, cross-referenced with existing features documented in the frontend and backend READMEs to avoid duplication. Emphasis will be placed on user-facing features and critical backend services.
## Sprint Planning Approach (Ecom App Project)
Sprints will typically be 1-2 weeks long. Each sprint will aim to deliver a potentially shippable increment of the e-commerce application. Sprint planning will involve:
1. Reviewing the prioritized `tasks_list.md`.
2. Estimating effort for selected tasks (Developer agent responsibility).
3. Defining a clear sprint goal focused on delivering value for the e-commerce platform.
4. Ensuring a balanced workload between frontend and backend development.
## Task Breakdown Framework (Ecom App Project)
Tasks will be broken down into smaller, manageable units by the Developer agent. The Scrum Master will ensure that each high-level task in `tasks_list.md` is a distinct, valuable piece of work. Examples of task categories for an e-commerce app include:
- User Authentication & Authorization
- Product Catalog Management
- Shopping Cart Functionality
- Order Processing
- Payment Gateway Integration
- User Profile Management
- Search & Filtering
- Admin Dashboards
## Agile Methodology Considerations (Ecom App Project)
- **Transparency:** All tasks, progress, and impediments will be visible to the team.
- **Adaptability:** The `tasks_list.md` will be a living document, adaptable to changing e-commerce market needs or user feedback.
- **Collaboration:** Foster close collaboration between frontend, backend, and other specialized agents.
- **Continuous Improvement:** Regularly review processes and outcomes to enhance efficiency and product quality.
## Customized Scrum Master Workflow (Ecom App Project)
1. **Initial Setup:** Create the `.sureai/.sm_agent_ecom_app_ecom_app_20251015_121220.md` (this file) and the initial `.sureai/tasks_list.md`.
2. **Backlog Refinement:** Continuously refine `tasks_list.md` by reviewing PRD, Project Plan, and existing READMEs.
3. **Sprint Planning:** Facilitate sprint planning sessions to select tasks for the upcoming sprint.
4. **Daily Stand-ups:** (Simulated) Monitor progress and identify impediments.
5. **Sprint Review:** (Simulated) Review completed tasks and gather feedback.
6. **Sprint Retrospective:** (Simulated) Identify areas for process improvement.
7. **Impediment Removal:** Proactively address any blockers for the development team.
8. **Communication:** Ensure clear communication across all agents and stakeholders regarding project status and changes.

## 4. Problem Statement
The current Angular Clarity Boilerplate provides a robust frontend foundation but lacks the specific functionalities required for a complete e-commerce experience, both for end-users seeking to purchase products and for administrators needing to manage store operations efficiently. The absence of a backend, product catalog management, shopping cart, checkout process, and secure user/admin roles creates a significant gap between the boilerplate's potential and a viable e-commerce solution. This project addresses the need to bridge this gap by integrating a powerful backend and developing all necessary e-commerce features within the existing architectural framework.
## 5. Solution Overview
The solution involves building a full-stack e-commerce application. The frontend will extend the Angular Clarity Boilerplate to include customer-facing features like product browsing, search, shopping cart, and a secure checkout flow, as well as a dedicated, role-protected administrator interface. The backend will be developed using Python Django, providing RESTful APIs for product management, order processing, user authentication and authorization (with RBAC), and an audit logging mechanism. A PostgreSQL database will handle data persistence, with Redis for caching, all deployed on AWS using Docker containers for scalability and reliability.
