High-Level Solution (HLS) - Proof of Concept (POC) Story

This HLS template for a Proof of Concept (POC) Story outlines the exploration, evaluation, and decision-making process for implementing a new concept, feature, or technology.

A High-Level Solution (HLS) for a POC should include:

• Objective & Scope: Define the purpose of the POC and what it aims to achieve.
• Exploration & Research: Document the approaches considered, references explored, and key findings.
• Comparative Analysis: Evaluate different solutions and select the best-fit approach.
• Implementation Approach: Provide a structured solution and execution plan.

1. Objective & Scope

Clearly define the goal of the POC and its boundaries:

• What problem or opportunity is being explored?
• What are the key expectations or success criteria?
• Which systems, components, or technologies are involved?

2. Exploration & Research

List the different approaches explored to solve the problem:

• Reference Links & Research Sources: Include documentation, articles, open-source projects, or APIs analyzed.
• Existing Solutions & Case Studies: Document similar implementations or industry practices.
• Technical Feasibility Analysis: Evaluate if the proposed solutions align with the existing architecture.

Example of Research Sources:

• Official Documentation of Technology X
• Case Study: How Company Y Implemented a Similar Solution
• Open-source GitHub Repository for Reference

3. Comparative Analysis of Approaches

Compare different approaches using a structured evaluation matrix:

Approach	Pros	Cons	Complexity	Performance	Final Decision
Approach A	Fast execution, easy integration	High cost	Low	High	❌ Rejected
Approach B	Open-source, customizable	Requires more setup	Medium	Medium	✅ Selected
Approach C	Scalable, widely adopted	Steep learning curve	High	High	❌ Rejected

Selected Approach & Justification

• Chosen Approach: <Mention the selected approach>
• Why it was chosen: <Explain why this is the best-fit solution>
• Expected Outcome: <State what improvements or benefits this brings>

4. Implementation Approach

Describe the structured solution using a step-by-step algorithm:

Algorithm POC_Implementation()
BEGIN
    1. Define the scope and success criteria of the POC.
    2. Set up the necessary environment and dependencies.
    3. Implement the core logic based on the selected approach.
    4. Test the concept under different scenarios and edge cases.
    5. Compare actual results with expected outcomes.
    6. Evaluate feasibility for full-scale implementation.
    7. Document findings and recommendations.
