Three-level full factorial design are often used only when two or three input factors need to be study, because an increased number of experiments is required. Optimization designs uses 3 to 5 levels of each input factors, which allow modeling 2nd order (quadratic) response surface. One of the most important limitations of screening designs rely on the fact that they only allow modeling 1st order (linear) response surface, because they have only two level for each input factor. In order to provide a better understand of DoE application, experimental designs may be divided into two types: a) screening designs and b) optimization designs. Selections of best experimental design should consider several aspects, such as defined objectives, number of input factors and interactions to be studied, and statistical validity and effectiveness of each design.

Which is a software based analytical tool used in pharmaceutical industry to analyze, improve, and validate pharmaceutical processes. To perform this job Minitab application will be a better option. In DoE approach, the controlled input factors are systematically varied to determine their effects on the output responses, which allows the determination of the most important input factors, the identification of input factors setting leading to optimized output responses, and the elucidation of interactions between input factors. DOE lets you assess the main effects of a process as well as the interaction effects (the effect of factor A, for example, may be much larger when factor B is set at a specific level. It is also useful in understanding how typical fluctuations around mean input values (e.g., starting materials) can influence the final product. Design of experiments (DOEs) is a very effective and powerful statistical tool that can help you understand and improve your processes, and design better products. When considering interactions of multiple variables that cannot be modelled simply, perform empirical tests (e.g., Design of Experiments - DOE) to map out appropriate operating ranges. It involves the execution of experimental design on the basis of suitable variables along with statistical evaluation of obtained responses and exploration of the design space using mathematical or graphical approach. The basic objectives of DoE are screening, optimization, and robustness.

Among various mathematical modeling approaches, Design of Experiments (DoE) is extensively used for the implementation of QbD in both research and industrial settings to avoid trial and error method was used in the past that led to several problems like non-reproducible, high-cost, and time consuming approach. Week 8: Blocking in Factorial Design, Response Surface Methodology. In QbD, product and process understanding is the key enabler of assuring quality in the final product. Week 7: Measurement System Analysis, and Factorial Design of Experiments using MINITAB. Where the quality of a product ensure by design not only the final product testing.

Use statistical tools: hypothesis testing, regression analysis, correlation, Box plot diagram, Pareto, Scatter diagram and SPC charts.Quality by Design (QbD) is a systemic approach to develop a pharmaceutical product with ensure that the intended performance of a final drug product is as expected.

Six Sigma iSixSigma Forums Old Forums General Minitab DOE. During this training course you will learn to use complex data analysis techniques by using software Minitab.

In practice we use only limited analytical tools and charts that do not allow us to reveal the real root cause of our problem. We collect a lot of data on all parameters of the process or product, but we are not able to evaluate these data effectivelly. In working life, we are often surrounded by data. There is no need to know mathematical formulas when analyzing, but you need to know how to prepare, collect and interpret right the data.
