Analysis and decision-making tools

I am passionate about analysis and decision-making tools. I am a collector.

When I estimate next year's sales or revenues (or anything uncertain), I use a triangular distribution over 3-4 scenarios.

When I choose holiday locations, or prioritize features on a roadmap, I draw a decision matrix.

Here is my collection of core tools and techniques for analysis and decision-making.

• Brainstorming
• Decomposition (e.g. X-BS), divide-et-impera
• Decision matrices
• Scenario analysis
• Triangular distributions (Worst case + 4 x Probable + Best ) ÷ 6
• Dependency modelling (DSM, DMM, MDM)
• Cost-benefit analysis
• Checklists
• SWOT
• PEST / STEEP
• Mind-maps
• Stakeholder maps
• Decision trees
• Cause-effect / Ishikawa
• Pareto (the 80-20 rule, sometimes 90-10)
• Delphi
• Focus groups
• Monte Carlo
• Causal-loop, systems thinking
• Process, workflow, component diagrams
• Toyota way
• 5 why-s
• WWWWWH (Who, What, When, Where, Why, How)

What tools do you use?
