Involving experts can significantly improve the accuracy of your project estimates. Here's how HoPM (Human and Organizational Project Management) can help you avoid issues with inaccurate estimates in the future:

1. **Expert Networks**: HoPM can facilitate the creation of networks of experts within the organization. This allows project managers to easily reach out to individuals with relevant experience for input on estimates.
2. **Knowledge Sharing**: HoPM encourages a culture of knowledge sharing where lessons learned and best practices from past projects are documented and made accessible, helping project teams to benefit from collective expertise.
3. **Collaboration Tools**: HoPM provides collaboration platforms where teams can discuss project details, clarify assumptions, and gather insights from multiple experts, leading to more comprehensive and accurate estimates.
