RACI is the matrix used to define roles and responsibilities for each action within a project. Machining requirements for the CNC processĬNC machining process to achieve the desired shape, size and surface finish The conducted SIPOC is shown in Figure 3. SIPOC was conducted for the machining process in which suppliers and customers are internal departments. SIPOC diagrams gather vital data about the beginning and end of a process and graphically represent the events necessary to get a given result. It is a tool used in the ‘Define phase’ for a high-level view of the process. SIPOC is the acronym for Supplier, Input, Process, Output and Customer. Figure 1 describes all the necessary information about the project team and resources.įigure 2: Process Flow Chart 2.1.3. Project objectives, scope, key metrics, the project team and schedule are also clearly defined in the project charter. It outlines the project description and the opportunity to implement Lean Six Sigma. Project Charter defines the process that needs to be improved.

This helps the stakeholders in understanding the problems and focusing on the objectives.

Starting with identifying the problem, the scope of the project and critical metrics are chosen. This process is done by developing the project charter. The first step establishes the project’s scope by defining the problems. This chapter includes the DMAIC methodology, which was applied to the process to achieve objectives. To reduce the rejection ratio from 0.5% to 0.25%.To reduce flatness from 0.2 max to 0.1 max.Implement lean six sigma methodology to improve machining flatness to meet internal machining rejection targets. Using the DMAIC approach for Lean Six Sigma could be useful to determine the problems and provide effective solutions. The opportunity to implement Lean Six Sigma exists as there’s no current system. The top management has decided to identify the cause and cope with the effects of the implementation of Lean Six Sigma in the process.

The supply efficiency is also severely affected. For the last few months, the company has been facing an inclining rejection ratio in-house as well at the customer end, which has become critical to the cost and goodwill of the company. Manufacturing company ABC provides aluminum to automobile industries and possesses a wide range of casting and machining setups. “Implementation of Lean Six Sigma methodology to improve machining flatness and meet internal machining rejection target” Project Report 1.
