number 1, degradability, is not the most important criteria, and number 7, cost, is not necessarily the least. Most of the potty used in healthcare nowadays are made of ubiquitous polymers such as Polyethylene and Polypropylene, which are generally non-biodegradable under normal environmental conditions. Thus, degradability is significantly low. For an overnight-or-one-day use product like healthcare potty, such low degradability is fatal to the environment, since they will accumulate really fast. Weight of the potty should be in an appropriate range, because of its short use time, customers are to carry the potty, plus the weight of the waste, to the disposal site quite frequently. Durability refers not only to its capacity to hold the waste but also, in some unfortunate situations of being dropped and/or hit, to maintain its form. Potty that breaks under usual types of contact, such as those mentioned above, will result in unhygienic scenes, which are totally undesirable in healthcare environment, that require lots of cleaning.

In order to do so, it is needed a quantitatively and quantitatively comparison between concepts. At first, a specification-criteria matrix in Table 6, which allows to compare different options in one specification, is made to evaluate the best option for each specification. The best options of each specification then made up to create an “overall” solution concept. This “overall” concept will then be compared to other mentioned solution concepts via concept-criteria matrix which provided in Table 7. This second comparison will help to decide the most desired concept for final
