OKR Goal Setting Framework

**Context**: The OKR (Objectives and Key Results) goal setting framework is a strategic management approach used by organizations to define and track objectives and their measurable outcomes. The framework helps teams and individuals set ambitious, inspirational, and measurable goals that align with the company's overall vision and strategy. 

**Detailed Instructions**: Create a comprehensive OKR goal setting framework for a fictional company, "GreenTech Inc.," a renewable energy startup aiming to expand its solar panel production and installation services globally. The framework should include:
1. **Company Objectives**: Define 3-5 high-level company objectives that align with GreenTech Inc.'s mission to lead the renewable energy sector.
2. **Key Results**: For each company objective, outline 2-3 measurable key results that will indicate progress toward achieving the objectives. These key results should be specific, time-bound, and quantifiable.
3. **Initiatives**: Identify 2-3 strategic initiatives for each key result that will help drive progress. These initiatives should be actionable, resource-intensive, and have a clear owner or team responsible for their execution.
4. **Metrics and Targets**: Establish relevant metrics and targets for each key result, including baseline values, target values, and the timeline for achieving these targets.
5. **Alignment and Prioritization**: Explain how the OKRs align with the company's overall strategy and vision. Prioritize the objectives and key results based on their impact, feasibility, and urgency.

**Output Format**: The output should be a structured document that includes:
- Introduction to GreenTech Inc. and its mission
- Company Objectives (with descriptions and rationales)
- Key Results (with metrics, targets, and timelines)
- Initiatives (with owners, resources, and timelines)
- Alignment and Prioritization (including a prioritization matrix or table)
- Conclusion summarizing the OKR framework and its expected outcomes

**Examples**: For illustration, consider the following example of an objective and its key results:
- **Objective**: Expand Global Presence
- **Key Results**:
  1. Establish operations in 3 new countries within the next 12 months.
  2. Increase international sales revenue by 20% year-over-year for the next 2 years.
  3. Achieve a customer satisfaction rating of 90% or higher in all international markets within 18 months.
Ensure that the provided OKR framework is comprehensive, well-structured, and tailored to the specific needs and goals of GreenTech Inc.
