Five What-Ifs℠

Making a change to a complex system without modeling it first is how teams create the next problem while solving the current one.

What it is

Before a sprint is planned, the Five What-Ifs℠ lets a product manager see how the full ecosystem reacts to a proposed change — not just the node being modified, but every downstream service that depends on it. The tool models your value stream as a network of services, each with a measured input volume, declared output paths, and a capacity ceiling. Change one assumption and the ripple effects propagate through the model in real time, surfacing the other changes you’ll need to make to keep the system running smoothly.

The five "what ifs" are the sequence of constraint questions the model forces you to answer: What if this node can’t absorb the additional volume? What if the overflow routes to a queue that’s already near capacity? What if the improvement in one area quietly degrades another? The ifs compound. The model surfaces them before the sprint, not after.

Why this matters

A change to one service rarely affects only that service. Increasing throughput at an upstream node sends more volume to the next one — which may not have the capacity to absorb it. Improving a conversion rate may shift the distribution across output paths in ways that stress a downstream queue. The Five What-Ifs makes these ripple effects visible before the sprint, so the team can address the whole cascade rather than discovering each constraint one surprised sprint at a time.

What you can do with it

  • Model your value stream’s actual flow: inputs, outputs, capacity ceilings, overflow paths
  • Launch a scenario from any objective and see how the ecosystem reacts — including services you weren’t directly targeting
  • Identify which other changes you’ll need to make before the primary change delivers its full benefit
  • Stamp a scenario to ratify it as the projection basis for the team’s planning conversation

Who it's for

Product managers preparing for sprint planning. Teams deciding whether to pursue an objective now or address a dependency first. Anyone who needs to defend a projection with something more rigorous than "we think this will help."

In the system

The Five What-Ifs canvas auto-populates from the Capability Spectrum — every service in your value stream becomes a node automatically. Scenarios are launched from the Objectives Backlog. Stamping a scenario advances an objective to Modeled state and surfaces the projection in the Alignment Ceremony’s Since Last Session view.
