The correct answer is: Multi-skilled teamworking
Rationale: Skilling was an important aspect of scientific management - but multi-skilled teamworking wasn't. Taylor's approach to job design (referred to in 'Micro-design of jobs' option) was to break jobs down into single, simple tasks which were given to an individual as a whole (specialised, repetitive) job for an individual. The other options are key techniques (which, as a question in the Pilot Paper pointed out, are still prevalent in some work environments today.)
