Design of Experiments

Effective project management relies on gathering the appropriate requirements for the project. It is also important for the project manager to plan quality measures  to deliver good product or service as well as to solve different kinds of problems that may arise for the project. This is the reason why quality planning is very important in managing projects.

Quality planning is a process that identifies relevant quality standards and determines how to satisfy them. It is important that quality planning should be implemented alongside other planning processes like risk planning and time planning because the changes in the quality of product, service or process may require a lot of changes in the planning processes.

When it comes to quality planning, there are several tools that can be used by project managers and one of them is the design of experiments (DOE). It is a technique that is used to identify different factors that can influence different aspects of the process or product during the time when it is being developed.  It is used during the quality planning management  to determine the type of tests and the different impacts they have on the cost of quality.

What this method does  is that it optimizes the processes and products. It also reduces the sensitivity of the product’s performance  that is caused by differences in the manufacturing processes and the environment.  The design of experiments provides the necessary statistical framework that can change all important factors systematically instead of changing them in iterative means.

The analysis of the data should yield the best conditions for both products and processes and should reveal interactions with all the factors that are associated with the project. This particular method will show the correlation within all factors involved in project management.
