“…In the last two decades, there has been an increasing trend in the number of original manufactured products (OMPs), which have outsourced multi activities by their suppliers (Suurmond et al, 2020). Supplier involvement (SI) concept is defined as the extent to how much the suppliers have several resources, capabilities, information knowledge and investments that can provide their partners with tasks, processes and developments, as a part or whole service in order to develop their customers' current products and future needs (Azadegan et al, 2020;Wang et al, 2021c).
