Providing a reasonable level of profitability through productivity is - and will remain - one of the fundamental tasks of the management teams of any production company. Manufacturing Cost Policy Deployment (MCPD) and Methods Design Concept (MDC): The Path to Competitiveness contains two new methodologies to improving the productivity and profitability of production systems that continuously increase competitiveness: Manufacturing Cost Policy Deployment (MCPD) and Methods Design Concept (MDC). Both MCPD and MDC are the result of long-time synthesis and distillation, being implemented successfully, totally or partially, in many companies. The MCPD system, developed by Alin Posteucă, is a manufacturing cost policy aimed at continuous cost improvement through a systemic and systematic approach. The MCPD is a methodology that improves the production flow driven by the need for Manufacturing Cost Improvement (MCI) for both existing and future products through setting targets and means to continuously improve production process productivity for each product family cost. The MDC, developed by Shigeyasu Sakamoto, design the effective manufacturing methods using a tool of engineering steps identifying ideas for increasing productivity called KAIZENSHIRO (improvable value as a target). The MDC results on production methods lead to effectiveness of work measurement for performance (P) and to knowledge and improvement of production control and planning as utilization (U), in order to achieve labor target costs. The combination of MCPD and MDC methodologies can provide a unique approach for the managers who are seeking new ways for increasing productivity and profitability to increase the competitive level of their manufacturing company.
