- Why are we testing? What are our intended outcomes and how well do various tests support these outcomes? How simple will it be to apply findings?
- What does the test claim to measure? (Some widely-used tests conflate behaviour and personality, for example.)
- Where’s the research? What kind of theoretical basis is there? Do the tenets align with our organisational values? Where are the findings to support the hypotheses?
If you know your intended outcomes, you're likely to choose more wisely and gain your ROI.
