When a project's scope changes, maintaining momentum on all fronts requires strategic planning. Start by reassessing priorities to ensure critical tasks are addressed across projects. Shift resources wisely without starving other initiatives, and communicate changes clearly to keep teams aligned. Empower team members to take ownership of their responsibilities, which helps distribute workloads effectively. Use technology like project management tools to track progress and stay organized. Finally, having a contingency plan minimizes disruptions and prepares for future shifts. By applying these strategies, you can keep all projects moving smoothly despite changes.

I'll assume the "change" is a scope increase: (1) find where you can cut the scope within the project. for a project already running for sometime, you should have a better understanding, and this may be possible (2) find re-use possibilities, within and from other projects (past, present or future) (3) do the above two steps in your other projects to see if there is some slack elsewhere which you can cut relatively painlessly (4) get your people to work longer, including weekends (5) - there are a lot of people here giving gyan about "clear communications", "team meetings" and such - if that's how your project manager sounds like, fire him/her - the incompetent/unimaginative PM is the reason you are in this mess

Start by re-evaluating priorities and resource allocation. Communicate clearly with all stakeholders about the changes and expected outcomes. Consider adjusting timelines and adding buffer resources to maintain momentum. Effective delegation and cross-functional teamwork are key here. Agile practices and continuous monitoring can also help maintain overall project health and delivery.

Let Team working on Projects A, B, and C. Project A (mobile app) requires significant scope changes due to new regulations. -Actions taken: Immediate sprint planning for Project A Communicated changes in daily stand-up Reassessed velocity and capacity across all projects Updated Kanban board to visualize new workload Moved two developers from Project B to A temporarily,Focused on critical user stories for Projects B and C,Maintained CI/CD practices Discussed handling of change in next retrospective -Key takeaways: Maintain transparency,Constantly reassess priorities Remain flexible in approach,Communicate effectively with all stakeholders,Leverage cross-functional team structure

Actually this is part of critical part in any project and I think it's one one of the main reasons for complete failure in a project. It's "The Requirement Management". In such big project requirement managment is not a small task, it's a core task or a main pillar for the project and without good management for the requirement in all levels the project delivery will impacted and harmed hevighly. Requirment Managment should be planned and controlled since the initial stage of the project till the end.
