There is no one ‘secret’ to improving productivity. It must be a team effort looking at big things like strategy and culture; and little things like execution and motivation. None of these can be left out.
The leaders of the organisation, set the mission, vision and strategy and are responsible for investment in key factors such as capital equipment, talent and skills. They also create the underlying culture. All of these create the potential for high productivity.
That potential is only realised when the workforce applies their talent snd skills to the execution of the action plans derived from the strategy. It helps tremendously if they are self motivated because of the supportive culture and effective communication so that everyone knows their value to the organisation and their role in the overall system.
So, don’t ask who is responsible for productivity improvement. You are? Along with everyone else!
