I agree with Roberto’s point. Every product has its own respective life cycle. However, durations of each phase will vary depending on the product. From your prompt, you mentioned sutures. Although the general concept of sutures have not changed, the method at which it is administered has greatly varied. Back then, they used ants as a way to seal cuts and incisions, nowadays biocompatible stitching is incorporated and even cauterizing methods are implemented during surgery, thus eliminating the need for a suture. This shows that there is a decline in the need for sutures. It is similar to the idea of having a refrigerator. The idea of the refrigerator has been in existence for a long time and the use of it I widespread till this day. It is basically present in every house. However, the method of keeping food fresh was different back then when they buried it in the cold ground. In the past couple of years, there have been numerous modifications to the original design of the refrigerator. This could be classified under the maturity phase of a product but again, I believe that it should be each design that should be evaluated.
