"The Lean Startup process for continuous improvement is (1) {{c1::identify the hypothesis to test}}, (2) {{c2::determine metrics with which to evaluate the hypothesis}}, (3) {{c3::build a minimum viable product}}, (4) {{c4::use the product to get data and test the hypothesis}}."

Does this become a single card with four blanks to fill or four cards that have all but one blank visible?
