    CSSC 2018 Research Group

    China’s economic development has entered the new era characterized by high quality development, which places deepening supply side structural reform in the first place of the important deployment of carrying out new development concept and building a modernized economic system, takes promoting “three de-, one reduction and one supplement” as major move, of which “one reduction” means reducing cost, stressing on comprehensive means to lower cost to enhance corporate competitiveness and expand quality incremental supply. These provide food policy environment and strategic opportunity for shipbuilding companies to accelerate and optimize industrial layout and regional layout and develop high-end manufacture, and put forward even higher requirements for shipbuilding companies to implement lean management, drive cost strategy, reshape cost advantages and improve core competitiveness.

    Overall Objectives

    Shipbuilding companies intending to implement lean management must closely combine overall development strategy, focus on top level design, take building and maintaining mid-term and long-term competitive advantages as overall guidelines, take management improvement as overall direction, carry forward and build the following frame models dubbed “one two three four five strategic cost project”, that is,improving shipyard’s comprehensive competitiveness, boosting corporate high quality development as one general objective, optimizing two deployments of industry and region, establishing three sets of systems of system,organization and standard, improving four operation mechanisms of overall coordination, budget management and control, information integration and risk early warning, and practically execute five driving factors of investment,manufacture, procurement, manpower and period expense.

    Specific Framework

    1. Adhere to one general objective.

    With promoting enterprises to realize the general requirement of midterm and long-term development as fundamental aim, general objective is to improve shipyard’s comprehensive competitiveness and boost corporate high quality development.

    2. Optimize two major deployments.

    1)Optimize industrial deployment.Firstly, in the light of international and domestic political and economic environmental changes, conduct comprehensive analysis and form effective countermeasures. Secondly, in line with changes in competitive environment,comprehensively analyze industrial comprehensive situations, incline limited resources to industries with cost competitive advantages to maximize corporate resource benefits. Thirdly,go on with driving product upgrading.Focus on core advantage products and continuously make refined and good products; give priority to development of high value-added products, gradually withdraw from low-end fields and incline limited resources to realms with cost competitive advantages.

    2)Optimize regional deployment.In combination with economic development environment, conform to rules of regional economic development and gradient transfer rules of globalization, comprehensively analyze advantages and disadvantages of regional distribution of capacity in factor costs,on the principle of benefit maximization,plan for regional layout of different industries in advance, and gradually adjust capacity to regions and countries with cost advantages.

    3. Establish three sets of systems.

    System is the foundation,organization is guarantee and standard is the norm, the three aspects make synergistic power to steadily support and jointly boost continuous strengthening and perfecting of the strategy cost management system.

    1)Institutional system. Firstly,establish a perfect basic system of cost control to normalize corporate cost management standard and requirements in the whole process of production and operation. Secondly, perfect cost control operation system, and develop cost control operability guidelines. Thirdly,consummate cost management system of incentives and disincentives, and develop a reward and punishment system closely related to cost management effect.

    2)Organizational system. First, set up strategic cost management organization as an arm of the corporate strategy committee, with corporate executive as head, and founder a special department or authorize to relevant department. Second,establish strategic cost management experts consultation committee composed of internal and external experts, actively use external brain function, jump out of cost and look at the cost, and jump out of cost and engage in cost. Third, explore the management format of establishing project cost director, conduct cost control from the whole industrial chain of the project and endow relevant authority.

Thirdly,intensify dynamic monitoring. Through cost management information system,realize dynamic monitoring of cost control key targets, identify problems and urge solution. Fourthly, conduct all-directional benchmark assessment, actively organize horizontal benchmark analysis with domestic pals and international advanced enterprises as well as longitudinal analysis with similar product costs, seek gaps,reveal shortcomings, and learn from others’ strong points and close the gaps.

Secondly, precise and accurate control of product cost. Constantly improve production technology process and operation model, improve productivity, and shorten product cycle.Thirdly, strict control of quality cost.Establish a systematic management regime system, constantly optimize control process, mend control loopholes and reduce internal and external loss costs.

    3)Procurement cost control

Secondly, implement material procurement tendering price ratio, and perfect supplies purchasing management regime. Thirdly, step up pricing trend study of raw and auxiliary materials in a bid to improve capability of timely purchasing at bottom prices and save procurement funds.

    4)Labor cost control
