There is a less possibility of achieving complete efficiency in any system but there are certain concepts to make it possible. One such concept is lean manufacturing. In this paper, bakery is taken as the industry and its process is studied. It has been analyzed that there are certain possibilities to make the process efficient. For that, the concept 5s, a Japanese concept is been implemented in the bakery and the efficiency of the process is increased. Also, process flow chart and Two handed process chart is has been worked out for the system and thus the productivity of the bakery is increased by eliminating the wastes. Index Terms: Lean, six sigma, 5s, process chart, two handed process chart, process industry, bakery, efficiency, productivity I. INTRODUCTION Lean manufacturing or the word "lean", clearly specifies the minimization of waste with a systematic method within a manufacturing system by increasing or not disturbing the productivity. [2] Wastes created because of the overburden and unevenness in the workloads are taken into account in Lean. Any customer would be willing to pay for the value in a process when it is taken from the client’s perspective. The non-value added activity that is decided to be the waste in many industrial processes comprise more than 90% of a factory’s total activity. [1] Many Manufacturing and service industries mainly trying to implement such lean practices and the adoption of lean is getting accelerated. The Process chart shows the operating and static position in relation to each other when the process is simultaneous. For repetitive opetations, the two-handed process chart is generally used, and when a complete cycle of work is been recorded. [7] What may be shown as a single operation on a flow process chart is considered to be broken into many number of elements to take up the operation. A process Industry (bakery) has been taken for implementing the Lean concept and productivity has been achieved. Revised Manuscript Received on August 05, 2019. T.

PROCESS OF BAKERY A Process industry like bakery which involves the production and selling process of flour based baked food items that consists of pies, cakes and breads. Bakeries can provide a wide range of deliverables that is related to the baking industry. Some bakeries will be specialized in handmade or traditional types of bread with local milled flour, or flour treatment agents. III. TYPES OF WASTE Muda, Mura and Muri are the three types of waste that was given by Toyata. [6] And other wastes that includes in any process are  Delay, that deals with the time variation from the actual scheduled time.  Over processing, that deals with the extra processing state that need not add any value to the process.  Over production, that denotes the extra production of goods than the demand.  Waiting, that denotes the actual readiness of the process but it should wait for the previous other processes to get completed.  Motion, that denotes the movement of the worker for completing a task.  Inventory, that actually describes the warehouse of a manufacturing unit that stores the extra produced goods.  Transportation denotes the movement of the materials or the products involved in the process. IV. THE APPLICABILITY OF LEAN SIX SIGMA IN THE FOOD INDUSTRY Lean Six Sigma have its great successful implementation and results in a common industry, but it is unfortunate that it is still very limited in the expansion of Lean in food industry as per the reviews[3]. But the case studies have proven that the possibilities of expanding the area of quality improvement in the industry that deals with food. [4]. And the main challenges faced during the implementation of Lean in such food process industry completely varies from the common industry in order to evaluate the high variable changing nature in the constraints that includes the fierce competition, the product quality, varying material costs and the requirements that are regulated [5].
