1. Transparent Communication: Clearly explain the reasons for the algorithm modifications, their impact on project goals, and how they align with stakeholder objectives. Provide data or examples to justify the changes. 2. Collaborative Decision-Making: Involve stakeholders by seeking their input and feedback on the changes. This ensures their concerns are addressed and builds a sense of ownership in the decision. 3. Regular Updates: Establish a system for periodic progress reviews to keep stakeholders informed about the implementation of the changes, any challenges encountered, and the timeline adjustments.

1.Clear Communication : Ensure transparency by explaining the reasons for modifications and the expected impact on the project timeline, resources, and outcomes. 2.Define Changes : Provide detailed documentation of the algorithm changes, highlighting the key differences and technical adjustment 3.Stakeholder Involvement : Invite stakeholders to regular meetings to discuss concerns, gather feedback, and ensure alignment. 4. Risk Management : Identify potential risks and mitigation strategies to address concerns about performance, scalability, and timelines. 5.Demonstrate Benefits : Emphasize how the modifications improve functionality, accuracy, or efficiency. 6.Continuous Updates : Keep stakeholders informed of progress and milestones.

While honesty and transparency are important, they may not be enough. Choose your best available diplomat in the team for the bad news delivery and initial negotiation.

first, demonstration of the change needed and its result, than moving forward to technical parts about the need for change. As long as we first show an excellent demo for our needs, creating it meaningfully, all the rest is erelvent.

To effectively engage stakeholders during mid-project algorithm modifications, start by clearly explaining the need for the change, focusing on how it aligns with project goals or addresses emerging challenges. Use accessible language to communicate the technical adjustments and their potential impact on deliverables, timelines, or costs. Invite stakeholders to provide input by presenting multiple solutions or asking for their priorities, ensuring they feel involved in the decision-making process. Maintain transparency by sharing progress updates, challenges, and adjustments through regular meetings or written summaries. Finally, emphasize the benefits of the modifications to keep stakeholders invested in the project’s success.

I assume that such late change is going to erode the trust between stakeholders and the project, so it is good to acknowledge and act accordingly. Be very clear about the reason for change, the reason for why it was discovered late and the measures the project-team is taking to not repeat such a re-work again.
