 In our quest for a framework to use, we found the LINCE methodology.

+LINCE's strengths over other methodologies mainly consist of reduced effort and duration.
 However, the way in which it is applied also makes it possible to pay more attention to the critical points of each product,
 giving more weight to concrete and practical tests that combat real threats than to dense documentation or exhaustive functionality tests.
 
 As most frameworks are not intended to be repeated very regularly, together with `jtsec <https://www.jtsec.es/>`__ we came up with an approach which
 makes it possible to pass the test twice a year, which is needed to align with our Business Edition releases.
