In a recent article Supply Chain Management as a Service (SCMaaS), a couple of interesting comments came up: (1) are there end-to-end applications available or just the sort of point solutions you’ve listed? Based on your broad definition of the supply chain, it would almost seem that a broad solution would be a cloud-based ERP; (2) are there vendors that focus on the planning side? The vendors you describe seem to be on the execution part of the process.
On another recent project (Wholesale Distributors; Do They Use ERP or CRM?), I found software that was advertised as addressing “Wholesale Distribution Software”.
Back to basics. Just what is a Supply Chain Management System?
