A company is initiating a project to decommission inefficient sales channels.

 The project manager should plan for incremental and iterative delivery based on feedback from the marketing and sales team because this is an example of adaptive development approach, which is suitable for projects with high uncertainty and changing requirements. By delivering value in increments and iterations, the project manager can validate the assumptions and benefits of the project, and adjust the scope and direction as needed. This way, the project manager can address the stakeholders’ concerns and ensure that the project delivers the most efficient and effective sales channels for the organization. References:
