English to Russian Social Sciences General / Conversation / Greetings / Letters organizational structure

From an outsider’s perspective, the organizational structure
of T. appears very hierarchical, constituting silos up to the
executive vice president level, despite efforts to fl atten the organization that began in the late 1980s. In 1988, the company instigated a move to limit the number of stamps of approval ( hanko ) required within each department from seven or eight to three.
Since 1989, it has flattened the seven layers of official status
within each division to three — staff manager, department manager, and general manager. These reforms helped to eliminate
functional bureaucracy within departments but did not eliminate
the silo mentality between departments such as the production
control department, the purchasing department, the finance
department, or the personnel department.
