Let's look at the natural life cycle of product development to understand at which stages testing can contribute to the emergence and successful operation of a product.
1.Ideation — nurturing an idea worth pursuing. Research helps identify unmet consumer needs, value chain opportunities, potential applications for innovation and new markets.
2.Screening — a rigorous approach to deciding which ideas are worth pursuing, again based on research and feasibility studies as well as an assessment of potential audiences.
3.Concept testing — testing how embodied ideas can work in the marketplace, leading to additional screening of less viable concepts.
4.Prototyping — designing products to test mass production capability, form factors and feature sets.
5.Early product testing — which assesses consumer attitudes toward the product itself, either in a controlled environment, in the field, or in an everyday context; usually unbranded or with highly simplified packaging.
6.Late product testing — which may include feedback from previous tests to refine the messaging, packaging and final form factor.
7.Testing iterations of the product to predict the impact (on sales and usage) of changes in features, formulation, targeting and marketing - often in response to changes in sales patterns or negative customer feedback.
As we can see that that testing is appropriate at almost any stage of product realization and carries its own special values depending on the stage.
Thus, product testing can be applied to:
- Find out how a near-final version of a new product might work.
- Configure this product to optimize its performance at launch.
- To test how the new product works after launch.
- Test the effect of changes in the product's design or presentation.
- Evaluate or study how the product is marketed.
- Test how well consumers in the new market will accept the existing product.
- Conduct a "penalty analysis" to find out what qualities, if changed, change consumers' opinions of the product.
Now let's take a closer look at the reasons why testing is important for a brand.
