Value stream mapping is considered as tool for regularising the flow materials from end to end. Different studies are made in this area in case to case basis. Accidents, strains, fatigues, defects are the main reasons for re-analysis but to improve productivity, implementing new technologies and for modernisation also present stream and future streams are prepared. Value stream mapping generally prepared on one component or multiple components in the supply chain. One completion of the existing value stream mapping, on the basis of brainstorming sessions the future scheme mapping is developed. The time interval of doing such analysis is depending on the area such analysis is made. Many areas in the supply chain require frequent analysis because of the dynamic nature of that component in supply chain. Preparation of distribution channel requires such analysis and it is frequently analysed to check the possibilities of 3rd party logistics and 4th party logistics. This paper is prepared on the basis of the study in the area of production operations on assembly line techniques. Material flow is calculated with the time consumption in each stage. Lean manufacturing practices is a part of having lean supply chain management. This article is concentrating only one component in the supply chain i.e. production, which is a major component in the supply chain. After making the analysis of Make or Buy and the Make decision taken, then the layout design is prepared. This layout design may have to for adequate changes during operations for many reasons mentioned above along with improvement in productivity. Whereas the costing of each product is based on the total fixed cost and the individual variable cost. Analysis is a discussing about the necessities of future scheme mapping.
