Supplier collaboration may fit nicely together with the ideals of sustainability in marketing material, but the relationship between the two concepts is underserved if we conflate them. For business, the ‘green agenda’ has been at various points a concern, a risk, a new market, an opportunity – but it’s consistently been a challenge to act across the value chain to effect change. In that respect, collaboration is a crucial strategy for reaching across industry, aligning goals and commercial outcomes. In so far as sustainability is a driver for collaboration, the mesh of different standards, the difficulty of measuring or auditing supplier performance, the return on investment, have all meant that few have been able to perform consistently and with results. By looking at the techniques and platforms that can open up collaboration, we can hope to achieve many of procurement’s fundamental objectives.
