The era of ​„sacred cows” of engi­ne­ering is slow­ly coming to an end. Software engi­ne­ering, after almost 20 years of an ​„agi­le” appro­ach to this branch of engi­ne­ering, is begin­ning to matu­re into ​„real engi­ne­ering” with ana­ly­sis, design and testing on the ​„dra­wing board” of CASE sys­tems and MBSE appro­aches, which are a uni­ver­sal sys­tems appro­ach to mul­ti­di­sci­pli­na­ry engi­ne­ering (mecha­tro­nics) (Rosenberg, 2023).

Organizations are also sys­tems and the­ir engi­ne­ering: we have busi­ness pro­cess engi­ne­ering, reso­ur­ce engi­ne­ering, finan­cial engi­ne­ering. Organizations are sys­tems and sho­uld be tre­ated and mode­led as such (Kozminski, 1979). IT sys­tems main­te­nan­ce and deve­lop­ment costs are alre­ady more than 8% of a com­pa­ny­’s reve­nue, and this value is slow­ly but ste­adi­ly gro­wing. The disci­pli­ne of the­ir cre­ation, imple­men­ta­tion and mana­ge­ment of the­ir costs is also growing.
