Many technical organizations have found it an advantage to create dual promotional ladders. This allows increasing competence and expertise the technical areas to be recognized. Recognition takes the form of salary, bonuses, stock options and other means of recognition. In 2017 the Industrial Research Institute conducted a survey and found that in large organizations, mostly in the chemical industry, the technical ladder is comprised between five and eight rungs (see the “Number of Ladder Rungs” figure). This is consistent with the entry-level to senior traditional management hierarchy in such an organization.
