Your team is faced with a complex decision. Maybe it's complex because you have a lot of options or maybe it's complex because it's technically challenging and requires some testing. You may want to consider a structured approach: DMRCS.
- D - Define - What are we trying to accomplish? What are our choices, including not acting?
- M - Measure - What metrics are we using to measure our choices against our goal and against each other?They should be precise, consistently applied, and fair.
- R - Reduce - Start narrowing in on the solution. Check: do our metrics and choices match up with what we're trying to do? Output meaningful, worthwhile solutions.
- C - Combine - Combine metrics to better understand the trade-offs of options
- S - Select - Make a choice
Just like six-sigma's DMAIC, the Define and Measure parts are the most important.
If you or your team are finding you're stuck in making a complex decision, try a structured approach to solving the problem. DMRCS may help your team find that structure so you can make informed decisions with high quality data.

I quote Dr. Anderson Cook in the podcast from this article:

The DMRCS model is presented in this article, with an example of choosing a job for employment.

See this article for another example of tools, based on a decision on which supplier to choose. These tools are highlighted: Pareto front, trade-off plot, mixture plot, efficiency plot.
