When we conduct our Grassroots Strategy workshops, a task on day one is to draw your value chain – the steps your offering goes through before reaching an end-user. In the business-to-business world, value chains can include different distributors, specifiers, installers and value-added resellers, all of whom can influence what gets bought by whom. We recommend looking at not just product flow, but also at how decisions and money flow up and down this chain.
