Test prototype and check assumptions
Testing is the final phase in the design process. In this phase you need to find out whether the assumptions you made in the design process are true or not and what influence this has on your business design. Here your research strategy is of the utmost importance. You need to ask yourself; what do I want to measure? How do I want to measure it? When I measure, will I measure what I want to measure? Will the results of my research be representative, reliable and valid.
In this final stage, the most important questions you want to answer are about the Innovation Space:
is the product feasible
technically
price wise
is the product desirable
experience
features
benefits
is the business viable
volumes
gross margin
costs for marketing and distribution
overheads
formulate critical path to success
formulate critical assumptions
test prototype to check assumptions
repeat step 2 and 3 when necessary
First check you business design for critical assumptions. Then formulate a main research question or hypothesis for each critical assumption and add sub-questions that specify the main question. Then elaborate on:
Research strategy and methodology
Research activities
Obstacles in obtaining information
Your strategy to overcome those obstacles
Reflection on the research process
List of papers and publications used
List of other resources and sources of information
