Shipbuilding is a nonlinear and modular process. Activities in production, design, management, and finance are interlinked and interdependent. That has been, but only partially, already tackled by PERT  and net diagrams depicting interdependence of activities, but in the production process mainly. We deem it desirable and indispensable to introduce all activities not only during the production process but in the preparatory stage as well, i.e. design, development of drawings, class and government bodies' approvals, purchase of materials, finance i.e. cash flow. The shipbuilding process in a broader sense includes also after delivery activities which should also be part of planning and prediction process. Our response time i.e. countermeasures could and should be instantaneous.... Shortening of the reaction time is the key to the success. Novum that we suggest is the definition of the whole, total, shipbuilding process as a number of interlinked and interdependent activities, activity modules.
