The importance of Design of Experiments (DoE)

Design of Experiments (DoE) is an important component in many industries. It is a series of tests or runs that is carried out repeatedly and consistently over a period of time, and its outputs or responses, observed. Design of Experiments is very important in industry to help arrive at an understanding of the predictability and reproducibility of an experiment.

Design of Experiments is a very important aspect of the important elements of a product, such as quality, reliability and performance. What Design of Experiments does is that it helps to examine and investigate the inputs that lead to poor quality. This insight leads the entity carrying out the Design of Experiments to use these to improve their quality standards.


Ruling out chance

Design of Experiments does not rely on chance or providence to bring about the quality that is required of an experiment. It arrives at the optimal set of procedures that are needed to get the required quality standards after a series of tests and experiments, so that the final result shows in the process that goes into the product.

Fundamentally, Design of Experiments helps to put in place a system of control for a product. All the ingredients that go into the inputs needed for obtaining a product of a defined standard or quality are scientific and precise. This precision and accuracy is arrived at after carrying out as many runs or series of Design of Experiments as needed to finally arrive at it.

An introduction to Design of Experiments

The ways of understanding Design of Experiments and applying their standards into production will be the topic of a webinar that is being organized by Compliance4All, a leading provider of professional trainings for all areas of regulatory compliance. At this webinar, the speaker, William Levinson, an ASQ Fellow, Certified Quality Engineer, Quality Auditor, Quality Manager, Reliability Engineer, and Six Sigma Black Belt, who is the principal of Levinson Productivity Systems, P.C., will explain the fundamentals of Design of Experiments.

An understanding of the significance level in hypothesis testing

William will make participants understand how to use Design of Experiments to identify and rule out the particular item or input that affects quality. The concept of significance level in hypothesis testing, which will serve as a basis for not only DoE, but also Statistical Process Control and acceptance sampling, will be explained.

A description of the other uses of DoE, such as supporting Corrective and Preventive Action (CAPA) and in process improvement, where it helps to identify and optimize the factors influenced by Critical to Quality (CTQ) characteristic, will be part of the learning that is on offer at this webinar.



Levinson will cover the following areas at this webinar:

·        Economic benefits of DOE

·        Hypothesis testing: the foundation of DOE, SPC, and acceptance sampling

o  Null and alternate hypothesis

o  Type I or alpha risk of concluding wrongly that the experiment differs from the control (or that a process is out of control, or that an acceptable production lot should be rejected)

o  Type II or beta risk of not detecting a difference between the control and the experiment, not detecting an out of control condition, and accepting a production lot that should be rejected

·        Factors, levels, and interactions

o  Interaction = “the whole is greater or less than the sum of its parts”. One variable at a time experiments cannot detect interactions.

·        Randomization and blocking exclude extraneous variation sources from the experiment.

·        Replication means taking multiple measurements to increase the experiment’s power.

·        Interpret the experiment’s results in terms of the significance level, or quantifiable “reasonable doubt” that the experiment differs from the control.

Managing healthcare projects with ease and simplicity

Those in the healthcare sector go about their work like they are completing a project. Their work is made up of many parts, all of which they need to approach using many processes and plans. In keeping a tight watch on the budget and the deadline; many aspects of the work get overlooked, as a result of which the outcome suffers.

Each team member has a specific and important task in healthcare. All these have to be done with precision and in close synchrony with the work of other members of the team. Getting this harmonious coordination right is at the root of putting in place a systematic process that helps to get work done smoothly and in an organized manner in the healthcare sector.

Learn ways by which to work like in a project

How does a healthcare organization get this? What role does each member of a healthcare organization play in bringing this whole project process right in order to guide the future of the healthcare system? This is the learning from a highly interesting webinar that Compliance4All, a leading provider of professional trainings for all areas of regulatory compliance, will be organizing.

Cathy Dolan-Schweitzer, who is president of Health Well Done and has developed a 3-step integrated approach to managing healthcare projects; will be the speaker at this webinar. Please log on to to enroll for this webinar.

Interpolating construction language into healthcare

The learning gained at this webinar will help the participants discover construction language, which is a strategy to reading plans. Cathy will help them experience the value of translating that into common language, so that the team shares and translates this wisdom and experience, usually applied in design and construction, to the medical professional. This experience, of course, is most important to the patient.

Nursing and clinical staff play a critical role in the hospital future improving quality in the built environment, designing spaces to influence the HCAP scores and engaging patient and staff advisory boards. Understanding design and construction language, plans and member roles when working on a project team can be challenging, but the speaker will help a simple three step approach that will make this easy. This approach will include using common language and tools to getting a patient centered healthcare project done. Using these techniques, the team can limit mistakes and reduce waste, while saving time and money.
