I am inferring that you want to get better outcomes from operational decision making, and quantifying something might help. I'd suggest looking retrospectively at the decisions you've made, the way you've been making them, and the role of those decisions in the outcomes you've seen. In terms of what factors shape outcomes, what is under your control, what is not? You'll want to model the range of possibilities and impacts of the stuff you don't control ultimately as distributions, and look to forecast outcomes as a combination of what you do and what else can happen, over the range of what you do and the range of what elses. That will look like a decision tree, and at a first pass you can model and evaluate that qualitatively, then shift to a quantiative model. The retrospective question is represent explicitly the factors your outcomes are most sensitive to, and then to focus more quantiatively from there - if it adds value.
Annie Duke's "Thinking in Bets" is a good book on decision making under uncertainty in a landscape (poker) that can be modeled quantitatively and in an environement that punishes thinkers that are not dispassionate. Like is not poker but the book is good on dealing with uncertainty.
In terms of hard decisions, Groopman and Hartzband, "Your Medical Mind", is an informed, lucid, and humane book on personal decisions related to healthcare. It's hard to know what to do, given data and advice or not. One line take away: see what people like you have done in similar situations, and how they feel about it.
In terms of strategic decisions, "A Structured Approach to Strategic Decisions", Kahneman, Lovallo, Sibony, [1] is for me the state of the art.
