Topic one questions
Question 1: Six sigma concept for SCM
Six sigma is utilised for making the process improvements which is essential in the
management of the operations and improving the quality of the overall processes such as
Supply Chain Management (Stanton, 2019). Six Sigma works on statistics hence it is an
effective tool that helps in predicting the future outcomes and also helps in bringing control
in the SCM which is critical for managing the demand and supply and hence bringing
efficiency in the overall process and decreasing the numbers of mistakes in the process.
Question 2: Two advantages of developing and utilising a QFD matrix
Different advantages of generating and utilising a QFD matrix has been showcased below:
 Customer driven: Since the development and utilisation of the QFD is done on the
basis of the demands of the customers hence the overall development process is
dependent on the wants of the consumers.
 Reduced development time: The likelihood of the design alters as the development of
this model emphasise on improvements that are done for satisfying the major
demands of the consumers. Higher attention towards requirements of the consumers
declines the threat that alteration will be needed lately in the life cycle of the project
(Quality-one, 2019).
Question 3: Each part of the QFD matrix
There are four parts of the QFD matrix. These include:
 Product definition: This phase starts with accumulation of the demands of the
customers and translating the demands of the customers into the product specification.
 Product development: In this part, the essential assemblies and parts are found out.
Essential product characteristics are cascaded down and translated to critical or key
parts and assembly specifications or characteristics.
 Process development: In this part, processes related to manufacturing and assembly
are planned on the basis of specifications of product and components. There is
development of process flow and essential process characteristics are also found out
(Borysowich, 2019).

 Process quality control: Before launching of the production, QFD process recognizes
essential parts and process characteristics. Process parameters are found out and
suitable process control are created and applied.
The QFD development is done through an approach and is in the cycle where four phases are
used in its development. These are product planning QFD, Component Deployment QFD,
process planning QFD and quality control QFD (Stewart, 2017).

Question 4: Steps for benchmarking
There are 10 steps for bench marking. These include:
 Finding processes which is to be benchmarked: It is critical to find out the processes
that need to be set for benchmarking and in this process there is elaboration of the
departmental priorities.
 Determining firms to be benchmarked: It is critical to effectively find out the
organisations that need to be benchmarked. An incorrect choice will not allow the
benchmark to be done appropriately.
 Gather data: It is a critical step in which plans for collecting the data from the selected
targets.
