Why? Choosing a starting point for scale initiative is very distracting. There are numerous real-time triggers like customer demands, business objectives, & Ops challenges. Which one to pick first is perplexing. This is similar to the service stabilization or improvement program and nothing close to SCALE.
What? Building an enterprise process catalog is the foundational activity to aspire scale. Process segmentation (division into separate parts), and categorization (Grouping) will help you consolidate the processes with similar characteristics, actions, and outcomes to start building the corresponding MVPr (Minimum Viable Process).
How? First, aggregate the processes to arrive at an MVPr. Then map comparable yet federated processes across other functions to the MVPr. This helps fast-track replication of the process or a part of it across every opportunity to save a significant portion of the time, effort, and investment, Multiplying the value achieved from the one-time effort. Scaling is about repurposing a one-time effort and extending that practice across the ecosystem by finding a fitment for that effort to enable other similar processes.
