Six decision making techniques

Sarah Hutchinson21 Aug 17

Decision making, prioritisation and reaching a consensus are some of the hardest and most important things in any business. Here is a practical guide to using six of the most useful decision-making techniques, widely used by facilitators.

Before we start, let's introduce three core concepts and human biases that are most likely to negatively affect your decision making process right now. By keeping them in mind you can make less biased and more effective decisions.

Three things to watch out for:

1. Groupthink

Groupthink is a powerful human bias which reduces our critical thinking ability. It comes into play whenever we see what other people are thinking. Subconsciously we will feel compelled to be part of the group, prompting us to agree with at least a few of the opinions expressed by other team members - we won't judge the options based purely on the information available and our thinking.

Help your team by concealing the results of a decision until everyone has decided what to vote on individually. You can also encourage people to play devil’s advocate and raise controversial issues by creating a supportive non-combative environment.

2. Social pressure

Social conformity, peer pressure and office politics can make people vote for options based on whose idea it is, and who else has voted for it, rather than the quality of the idea itself.

By making voting and option generation anonymous, you can reduce social pressure and get less biased results. If you are the most senior person in the team and you want their honest opinion, that's one way to get it.

3. Vote splitting

Combine or remove similar ideas to avoid confusing results. For example, as a restaurant owner, which option should you choose to focus your marketing budget on?

Vote splitting example

Steak and chips is clearly the most popular option, but if you go for that you’re disappointing the 9 people who voted for a vegetarian option. If there were two meat dishes and two vegetarian dishes, would steak and chips get the same amount of votes? Probably not, and the winner may be either a vegetarian or non-vegetarian dish, but the winner would be less likely to depend on that divide.

Six decision-making techniques

Now, how can you apply these facts to make less biased and more effective decisions? The following six techniques can help. Each technique is more sophisticated than the previous one. Our general advice is to use the simplest technique that gives you a good enough decision.

The sixth technique is a game technique if you have to make a decision but you'd like to have fun while you do it.


  • Everyone votes for only one option.
  • Use this when you don’t have many options.
  • Works well in large groups.


  • Everyone can vote for several options.
  • Use this when you have lots of options.
  • Works with any group size.


  • Everyone orders the options.
  • Use this to make a final decision of what to focus on.
  • Works well in small or medium groups.

4. 2x2 MATRIX

  • Everyone arranges the options according to two criteria.
  • Use this when you have lots of options and want to know what to prioritise.
  • Works well in small or medium groups.


  • Evaluate each option against multiple criteria.
  • Use this when you have a few competing options.
  • Works well individually or in small groups.


  • Play a game to make quick, fun decisions.
  • Use this when you have a lot of options.
  • Works well in small groups.
