The Strategic Decision Model
Strategy is a decision about what to change. SDM is the method StrategySOS is built on for making that decision in a structured, defensible way — one level at a time.
Strategy is an idea that employs the most relevant and effective parameters of change which, when brought into effect, can produce the desired outcome.
Every organization operates inside Limitations — the conditions, forces and boundaries that shape what it can realistically pursue. Some limitations can't be changed. The ones that can become Parameters of Change: the specific things an organization can act on to alter how a limitation affects its desired outcome. SDM is the discipline of finding those, weighing them honestly, and choosing the ones a real strategy should rest on.
Look at the situation from every angle before deciding what to do
Limitations get missed when they're only viewed from one direction. SDM starts by examining the situation through four distinct drivers.
Name the conditions, then find what you can actually change
A Limitation is a condition that matters to the outcome you want — it can exist at the Corporate, Business or Functional level, and it can come from any of the four drivers above. Naming it precisely is the first real step, because a strategy built on the wrong limitation solves the wrong problem.
Not every limitation can be influenced. The ones that can become Parameters of Change — concrete, specific actions or areas of intervention. A limitation like “the market is shifting toward subscription pricing” might turn into Parameters like “introduce a subscription tier” or “retrain the sales team on recurring-revenue selling” — illustrative examples, not a formula; the real Parameters always come from your own situation.
The goal is the changes that matter most, not the longest list
Every Parameter of Change is scored on four criteria, so the choice of what to pursue is a judgment made against consistent evidence, not a gut call.
The Parameters you select become your Strategic Direction
Once the highest-value Parameters are chosen, StrategySOS compiles them into a Strategy Statement — a plain-language articulation of the strategy, generated from what you actually selected, not written from scratch. You can edit it, and lock it once it's the version you want to stand behind.
The same process repeats at every level — Corporate, Business, and every Functional Strategy — and each level's Statement is expected to connect to the one above it. That connected chain, not any single Statement on its own, is what SDM is actually for.
