One idea: how much profit an industry can make is set by five competitive forces. You rate four of them, and watch how together they drive the fifth, competitive rivalry, right at the centre.
Pick an industry. You'll rate four of its forces, then can come back and compare another.
Michael Porter argued that how profitable any industry can be is shaped by five competitive forces. Four of them (buyer power, supplier power, the threat of new entrants and the threat of substitutes) press in on the fifth: the competitive rivalry at the heart of the market.
Your task: rate those four forces, watch how strongly they (and the way the industry is built) drive rivalry, see the overall attractiveness build up live, compare with an expert, then choose a realistic move to ease one force.
This is about how the market is built, not a verdict on any one company.
There's no single right answer. Make a judgement and move the slider. The diagram and the attractiveness read update as you decide.
There's no single right answer here, and sensible people will differ. Compare the reasoning, not just the rating.
You can't change rivalry directly, but you can ease the forces that drive it. Pick a force the expert rated High or Very High, choose a realistic action, and watch rivalry and the score respond.
You rated buyer power, supplier power, new entrants and substitutes for a real market and saw why each is strong or weak.
You saw competitive rivalry come from the other four forces and how the industry is built, not as a separate choice you make.
You eased a force with a realistic move, watched rivalry follow, and weighed up the trade-off.
