Practical tools for better decisions
Subject
Themes
Every decision carries the weight of cognitive bias. Confirmation bias leads people to favour evidence supporting their existing beliefs while dismissing contradictory information, and the Dunning-Kruger effect causes the least competent to feel most confident in their judgement. These distortions cannot be eliminated, only managed through structured tools and frameworks that impose discipline on an inherently subjective process.

The landscape of decision-making literature shifted significantly in the early twenty-first century, moving from academic theory toward practical application. Published in 2016, this work arrives at a moment when professionals face mounting pressure to make faster, better-informed decisions in…
Every decision, no matter how carefully considered, operates under the influence of cognitive biases that distort perception and judgement. Two biases stand out as particularly destructive in professional settings. Confirmation bias drives people to seek and favour information supporting their…
Ockham's Razor, a principle from the fourteenth century, provides the most important meta-rule for decision-making: among competing approaches, the one requiring the fewest assumptions should be preferred. This ancient philosophical guideline translates into three practical questions that every…
Brainstorming occupies a unique position in professional culture: universally practised, widely trusted, and fundamentally broken. Research by Mullen, Johnson, and Salas in 1991 established that brainstorming groups produce significantly fewer and lower-quality ideas than nominal groups, where…
Sound decision-making demands thorough understanding of the environment before any analytical tool is deployed. The OODA loop's first phase, Observe, underscores this requirement: skipping or mishandling observation leaves only hope as a strategy. Multiple tools exist to map context systematically,…
Once options have been generated, the challenge shifts to evaluation and selection. This phase is where most professionals default to a simple pros and cons list, a method so basic it fails to account for the varying importance of different factors, the cognitive biases of the evaluator, or the…
Brainstorming, despite its widespread popularity, stands as possibly the most overrated decision-making technique in use. Research by Mullen, Johnson, and Salas in 1991 demonstrated that brainstorming groups produce significantly fewer and lower-quality ideas than nominal groups, where individuals…
GROW (Goal, Reality, Options/Obstacles, Will) provides a straightforward four-step framework for problem solving. The Goal phase demands clarity about what needs achieving, ideally defined with measurable SMART indicators. Reality requires honest assessment of progress to date, including actions…
Porter's five forces framework analyses competition within a market to support strategic decision-making. Five competitive forces determine industry attractiveness and profitability: the stronger any force, the lower the profitability. Three forces operate horizontally. Competitive rivalry reflects…
The Kipling Method, also known as 5W1H, analyses problems through six question types: Why, Who, What, Where, When, and How. Applied to low employee productivity, these produce questions like: Why is output too low? Who specifically has low productivity? What is the current status? Where does the…
Grid Analysis plots solutions against criteria in a table. An office relocation example evaluates four city areas (North, South, East, West) against relevant factors, scoring each option per criterion and summing totals to reveal the best choice. The tool excels under time pressure due to speed and…
The Eisenhower Matrix stands as perhaps the most famous prioritisation tool, built on Dwight Eisenhower's insight that what is important is seldom urgent, and what is urgent is seldom important. A four-quadrant box measures every task against Urgency (deadline proximity) and Importance (impact on…
The Nominal Group Technique (NGT), developed by Delbecq and Van de Ven in 1971, offers a structured alternative to brainstorming that overcomes typical groupmind blocks. Seven steps guide the process. A moderator poses a question, such as how to increase turnover. Members write down ideas…
DeBono's Six Thinking Hats, introduced in 1991, channels group discussion through six sequential thinking modes. All members wear the same metaphorical hat simultaneously, with no going back permitted. The White Hat restricts discussion to pure facts. The Green Hat opens the floor to creative idea…
The Advantage Matrix, also developed by BCG, analyses competitiveness along two dimensions: the size of competitive advantage (economies of scale) and the number of approaches used to achieve it (differentiation). A competitive advantage exists when a firm delivers the same value at lower cost or…
The Plus Minus Interesting (PMI) analysis, developed by Edward de Bono, evaluates decisions through three columns: positive points, negative points, and interesting points (indirect consequences that could go either way). Each item receives a numerical value, and summing across all columns produces…
