                   Notes         7.3 Summary

                                    •  Software Verification and Validation (V&V) is a systems engineering discipline helping a
                                      development organization build quality into the application software during the software
                                      life cycle.

                                    •  Services  must  be  provided  and  managed  by  an  organization  that  is  technically  and
                                      managerially independent of the subject software development project.
                                    •  Verification  is  the  process  of  testing  like  set  of  documents,  plans,  specifications  and
                                      requirements.
                                    •  The area provides traceable and reproducible work products and processes for stockpile
                                      certification  (short  and  long  term),  as  well  as  foundational  elements  for  establishing
                                      software quality standards and training weapons scientists in the application of verification,
                                      validation, and UQ methods.

                                    •  A validation metric is the basis for comparing features from experimental data with model
                                      predictions.  Validation  metrics  are  established  during  the  requirements  phase  of  the
                                      conceptual model development and incorporate numerical and experimental uncertainty
                                    •  Network metrics for design focus on the structure chart (mostly the call graph component
                                      of the structure chart) and define some metrics of how “good” the structure or network
                                      is in an effort to quantify the complexity of the call graph.
                                    •  The inflow of modules the total number of abstract data elements flowing in the module
                                      and the outflow is the total number of abstract data elements that are flowing out of the
                                      module.
                                 7.4 Keywords


                                 Amplitude: It is the objective measurement of the degree of change (positive or negative) in
                                 atmospheric pressure (the compression and rarefaction of air molecules) caused by sound waves.
                                 Impurity: It is that substance which is or is added in elements mostly in semiconductors in order
                                 to make it more stabilize as required.

                                 Shock Response Spectra: The shock response spectrum (SRS) is quite often used in the analysis
                                 of transient shock to help establish design criteria and test specifications.

                                 Testing:  It  is  the  process  of  running  a  system  with  the  intention  of  finding  errors.  Testing
                                 enhances the integrity of a system by detecting deviations in design and errors in the system.

                                 Validation Metric: It is the basis for comparing features from experimental data with model
                                 predictions.

                                                2. Differentiate between Verification and Validation.
