In the present scenario, it is necessary to follow lean manufacturing techniques more effectively and efficiently in order to meet the challenges of the global competitive market. Hence it is inevitable to introduce lean techniques which increase the productivity and reduce the lead time that ultimately results in customer satisfaction. Lean manufacturing has widely been executed in large scale industries over the past three decades. Lean means nothing but the creation of more value for customers with fewer resources and is the current trend for management of products and services. Companies are able to respond to changing customer desires with high variety, high quality, and fast throughput times with low cost. Also information management has become much simpler and more accurate. The main aim of this paper is to study the existing system in a small scale automotive component manufacturing industry and use lean tools to reduce lead time without greatly affecting the current working systems in the industry. Standard Operating Procedure (SOP) is used to standardize the production and Kanban is also introduced by indicating the part number and part description to all work stations. Ranked position weight method in line balancing is used to reduce the transportation time of products from one station to another. Cycle time and setup time were reduced by about 350 seconds and 1500 seconds by work standardization and hence the productivity also increased. After implementing SOP the overall lead time reduced from 5780 seconds to 3946 seconds.

Purpose With the increase of state capital, corporate total factor productivity (TFP) has a tendency to jump up at first and then slowly decrease. Generally, no significant “productivity paradox” can be observed in China’s manufacturing industry. With the increase of export density, corporate TFP also shows a trend of initial jump growth and subsequent slow decline. This paper aims to discuss these issues. Design/methodology/approach Using the 1996–2013 China Industrial Enterprise Database, this paper studies the monopolistic behavior of Chinese manufacturing enterprises through the measurement of TFP and corporate monopoly power. Findings Results show that China’s manufacturing monopoly enterprises are generally innovation-oriented rather than rent-seeking. However, there are certain differences between diversified types of monopoly enterprises: the ones with state capital are more inclined to innovate than those without, whereas the ones with export delivery value are more inclined to seek rent than those without. Originality/value Therefore, the government should implement differentiated policies for diversified types of monopoly enterprises, and do so in a targeted manner fully reflecting the containment of rent-seeking and the encouragement of innovation.
