A method for evaluating the ease of disassembly of products is presented. Its primary use is in designing products for recycling and making environmentally-related decisions, but it is also relevant to servicing and maintenance. The evaluation procedure is centered around a spreadsheet-like chart and uses a catalog of task difficulty scores. The scores were derived from work-measurement analyses of standard disassembly tasks and provide a means of identifying weaknesses in the design and comparing alternatives quantitatively. The requirements and considerations in developing the design tool are examined in light of the general problem of manufacturability metrics. The limitations of the method and future extensions are discussed.
