The procedures that a methodology recommends for performing assessment activities are assessment tools. For example, the weighted-sum method of rating is a tool for prioritizing a list of waste reduction implementations. Alternative tools include simple voting or assigning options to each category as do-now or do-later. An effective methodology avoids presenting a single tool for performing an assessment activity. Providing multiple tools from which a production area can choose imparts flexibility to a methodology and makes it suitable for a variety of processes and waste streams.
