Six Sigma Implementations – Business       

      Six Sigma is a common quality management practice used to help businesses improve their current processes, products or services by detecting the defects and find ways to eliminate them. Many successful examples by well-known companies demonstrated this methodology`s efficiency such as in Motorola, Amazon, General Electric…..etc.

     In practice, these companies use one of two paths to implement six sigma: DMAIC, which contains five phases ( Define , Measure , Analyze , Improve , Control ) , and DMADV which includes ( Define , Measure , Analyze , Design , Verify ). The first path is covered in details by our course materials.

       In this assignment, suppose that you are working at a company as Quality Records Investigator. In order to improve a current process, product or service, you were asked by the manager to create a plan using six-sigma methodology specifically (DMAIC).

To work on this assignment, choose a product or service, or process that you think it needs to be improved.

Answer the following Questions:

1. Define Stage : Product or Service Information: ( 1 point )

• Choose either product, service, or process to improve.
• Define the project scope, two objectives, and the duration.
• Identify the project`s team (key stakeholders).

2. Measure stage: ( 1 point)

• Use a process flowchart to identify the current process for your choice ( Inputs , action , outputs)
• Choose a measurement for your analysis (Nominal, Ordinal, Interval, Ratio).

3. Analyze stage : (1 point)

Based on your process flowchart and your desired outcomes, Define the Sources of Process Variation. (Causes of problem, or non-value processes)

4. Improve stage :( 1 point )

• Present no more than two conditions that have to be exited to work your desired plan.

5. Control stage :( 1 point )

• Identify two tangible & intangible measurements that the company can use to evaluate their performance after the improvement.
• In which way the company can help their employees to embrace the new changes (training, reward system ...)

Answer 1

DMAIC METHODOLOGY

A methodology commonly used in six sigma to improve existing processes is the DMAIC model. The DMAIC cycle is a framework for problem solving which breaks down the process into five steps

*Define

*Measure

*Analyze

*improve

*control.

Six Sigma implementation at Wipro

Wipro is the world's first CMMi* level 5 certified software company. Earlier it was a vegetable oil company and converted itself into global IT services giant after liberalization. Now they changed its field operations. They faced a lot of problems . Managers felt that there was a need of aligning business operations with customer needs and continuous improvement. Therefore Wipro moving began moving towards focus on quality. thereby creating a learning environment that lead to implementation of six sigma.

Wipro has evolved following six sigma methodology for developing new processes

1.Developing six sigma software.

2.Designing six sigma process and product.

3.Design for customer satisfication and manufacturability.

objectives

*On time delivery

Shifting from the internalized approach to customer orientation through the introduction of six sigma concept.

*Improved quality

*For the customers.,this focus on excellent in quality process as resulted in better adherence to project schedule reduced error rate ,better estimation capabilities and minimizing the number of rejection.
