You may not have time for this idea but it may meet the "low-cost" criteria, if the company likes it.
A few years ago a local company create their own training video (wastewater reduction related). An employee volunteered the use of their video camera and a team comprised of management & employees tackled the job. The completed video was reported to be an instant in-house hit when used for training. All the major in-plant personalities were included in the video as well as the actual equipment/in-plant processes/etc. In addition to addressing water reduction issues, a lot was learned about safety and general waste reduction. Additionally, it was reported the project created a very good sense of teamwork in the plant which improved communications - a perfect start for continued improvement.
