[7] It was called the Scaling Up Management (SUM) Framework, it was subsequently refined and expanded in Editions 2 and 3, both of which include the MSI Scalability Assessment Tool.
Most recently, the International Maize and Wheat Improvement Center (CIMMYT) and the PPPLab[i][14] developed the Scaling Scan.
[15] All these frameworks assign the difficulty of scaling innovations to a lack of clarity about what is required to achieve sustained results beyond smaller pilot programs.
The tools help simplify and explain the complexities of scaling and guide users to systematically think through key elements, ingredients, or success factors.
