How To Plan Ahead
The more you plan up front, the better the chance of a successful project/activity. At the end of the project/activity, both you and the corporate volunteers should feel the effort put in was really worthwhile.
The project and tasks should be clearly defined and valuable to your mission. Once you decide on the overall outcome you want, break the work into as many individual tasks as possible; a task should be work that can be easily delegated to an individual or small teams. Then consider any specific skills required to do the tasks. You also need to consider if you have enough support staff, tools, training, information etc. to make the day as productive as possible.
Remember, most corporate volunteers have a day to contribute. They thrive on being busy and can become disengaged if they are not kept busy all day. So, if anything, err on the side of having too much work for a day rather than not enough. If you don’t have experience with this type of project, your Divisional Volunteer Resource Coordinator can assist with the breakdown of tasks and how many corporate volunteers you need or can accommodate.
