Using Historical Data in the context of House of PM (HoPM) can help avoid poor initial estimation problems in the following ways:

1. **Repository of Past Projects**: HoPM can serve as a central repository for past project data, including budgets, timelines, and lessons learned, making it easier to access and reference historical data for future projects.
2. **Benchmarking**: By analyzing past projects of similar scope and complexity, you can create benchmarks for costs, which can lead to more accurate estimations by comparing new projects against proven data.
3. **Estimation Tools**: Many HoPM frameworks have tools and methodologies designed for cost estimation, based on historical data, which can streamline the estimation process and enhance accuracy.
