it means that the assessment and the improvement actions were
not adequate, thus another implementation of the procedure is
required.
-Notice how the application of the method finds its natural best
performance when it is applied in a continuous improvement
framework, such as the Deming wheel (Fig. 4), i.e., where there is
a continuous improvement led by the cyclic application of phases:
(i) plan, (ii) do, (iii) check, (iv) act. This is typical of all Management
Systems that pursue continuous improvement strategies, like
Quality or Safety Management Systems planned as in ISO EN
9001:2008 or OSHAS 18000
