Apple Supply Chain Management And Logistics

Interface between Production and Logistics: Through appropriate logistic channels, completely assembled products, from different manufacturing units of Apple supply chain management, are made available in the market, according to the demands of the consumers. As opined by Cousins, Lawson, Petersen & Fugate $(2019),$ the labor cost is minimal in the nations of Asia, while the availability of raw materials for the manufacturing process is high and transportation facilities are readily available, which reduces the manufacturing expenses of the company. The logistics helps Apple Inc. in maintaining a balance between the demand and supply of the products, through making the raw materials available to the manufacturing units timely while shipping the finished goods efficiently, to the storage and distribution facilities, as and when required, so that the lead time for the products in the market is less.

Interface between Marketing and Logistics: As stated by Dubey et al$.,(2017),$ two very important aspects of marketing mix, Place and Product, are directly impacted by the logistics systems, at Apple Inc. The logistics systems ensure that the product is delivered at those points where there is an increased demand for the same, while managing the inventory and stocking$-$up products in storehouses, to minimize the lead time, when the customers demand the products, in other markets. The marketing department, on the other hand, through market researches, helps the logistics department to gain a clear idea regarding the predicted demands of the customers in the market and thus, plays an important role in inventory management.

Interface between Accounting & finance and Logistics: Apple supply chain management is considered to be a financially stable company where investment can be made as it has the increasing trends of earnings. The Gross profit has changed from $33\mathrm{.}97\%$ to $35\mathrm{.}96\%$ and the percentage of operating income has increased from $18\mathrm{.}37\%$ to $20\mathrm{.}96\%.$ The logistics system, through their effort to minimize the lead$-$time and to make the products readily available to the customers, as per their demand, according to the market trends, helps in maintaining the profitability of the company.
