Not sure what you mean by 'even you'.
If there is a Standard that, if implemented, leads to equipment delivered to time, cost and performance (with literally thousands of examples available); that explains the procedure for fixing almost every support problem; demonstrably would have prevented many accidents (XX177, ZG710, ZD576, XV230, etc); and in any case makes unnecessary 90% of recommendations in Board of Inquiry/Service Inquiry reports; then I simply suggest adhering to known good practice (and mandates).
I fully agree there is a need to 'modernise'. The various terms in the Standard need updating, and around six of the accompanying Specfications are now redundant, and probably need replacing to reflect newer capabilities. Even so, it remains perfectly clear.
A separate issue is why the Standard has officially been deleted, yet still forms the basis of, for example, the Infantry's flagship programme whose sole aim is to reduce casualties. That is where MoD won't go.
