What is a simple construct to measure the performance of channels of distribution?
For example, if we want to compare the return on investment in channels of distribution among different companies (in my case they are SMEs). What would be a simple construct to compare channels performance?
Another example if we want to track the channels performance over the lifetime of the organization what would be the measure?
Although this is important to my current research but it is not central. Therefore, I do not need to go for multiple scales, nor I want to go in contraventional discussions I just need a simple generic construct that is safe to use in measuring the performance of the channels.
