Your proposal is really a sales document and your manager is your potential customer. Show that you have troubleshot the potholes, thought realistically about how to make it work smoothly, and anticipated how it will benefit your manager and team members. Let your manager know that you are willing to adjust your plan, if necessary, to suit the needs of the business. Finally, like any reliable product, offer a free trial period.
