Value
Effective network management can provide positive strategic impacts. For example, in the case of developing an infrastructure, providing participants with some interactive space allows them to collaborate with each other, thereby promoting overall benefits. At the same time, the value of network management to the strategic network is also affected by the relationship between participants. Active participation, interaction and collaboration can make them more trusting of each other and enhance cohesion.
