When designing your project proposals, consider these things:
The project must be realistic in scope and be able to be completed in the given timeframe (2-3 months for consultancy work, 4-5 months for project-based work).
The project should produce sustainable results, allowing your organization to better serve the community and be strategic, structural, operational, or organizational in nature.
The nonprofit agency must be open to new and innovative ideas that the team will provide.
The nonprofit agency must have the capacity to communicate with the team regularly, meet with the team regularly, and work with them to make decisions quickly regarding the direction of their project.
Make sure your submission is clearly written so the teams can understand exactly what you are asking.
