Creativity Exercise: Expand and Shrink

Creativity Exercise: Expand and Shrink


When engaged in a brainstorming session on productivity, you want to maximise your search efficiency in order to systematically explore all areas and get the best from the time spend on the problem. A great way to do this is to expand and shrink the problem so you can come up with new ideas, get rid of the bad ideas and move forward.

Effectively, you can use the following 5 techniques:

  • Expand. Expand the problem by thinking of new associations on all directions.
  • Reduce. Reduce the scope.
  • Reverse. Come up with something opposite to explore new avenues.
  • Eliminate. Remove those ideas that don’t make any sense to reduce your search space and increase the efficiency of your brainstorming. After all, you can’t spend forever on this topic so you need to setup boundaries.

The following exercise helps the delegates to use this method.

For ready-made training content on this and further exercises, consider Creativity and Innovation Training Materials.


Use Expand, Reduce, Reverse and Eliminate on a problem to brainstorm it.

What You Need

  • A couple of flipcharts for each group.
  • Coloured pens.


  • Divide the delegates into groups of 4 or 5.
  • Ask them to consider a problem. If they are from the same organisation, it is better to select something relevant to their work.
  • You have two options:
  • A. If you have trained the delegates about mind maps, ask them to carry out this exercise using a mind map approach. Indeed, this is the preferred option. Ask them to write the problem at the centre of the screen. Add 4 main branches to this title as Expand, Reduce, Reverse, and Eliminate
  • B. If they don’t know about mind maps, ask them to write the problem at the top of the flipchart and then draw 3 lines to form 4 columns. Title the columns as Expand, Reduce, Reverse, and Eliminate
  • To better clarify what is required, you can show delegates the example provided below.
  • Allocate 15 minutes for groups to brainstorm the topic and write their ideas on their flipcharts.
  • Ask everyone to get back together and ask each group to present their problem and their solutions. Ask other group to comment on their work.
  • Follow with a discussion.


Explaining the Test: 5 minutes.

Activity: 15 minutes

Group Feedback: 10 minutes.
