How to use Design of Experiments Effectively?

Design of experiments is a tool to predict possible outcomes and planning the delivery under empirically stated conditions. This is a systematic method aiming to determine the relationships among the factors involved in the process. Its level of influence is also measured to manage process inputs. It requires knowledge on statistical tools, and experimentation concepts, which are vital in the implementation of the experiments.it is important to know its basic before implementing it using software programs. This process involves planning, conducting, analyzing, and interpreting tests to evaluate the factors affecting the flow of the process in the system.

Here are the steps on how to use Design of Experiments

Step 1: Set Good Objectives

Nothing beats clear and concise objectives. Make sure that these objectives are specific, measurable, accurate, results-oriented and time-bound. Having unclear goals may impede the process to move further and may always bring you back to step one and the history repeats itself. Establishing goals at the beginning builds deeper and firm understanding of what is needed to be done. A strategically planned and executed experiment may provide not just good, but great deal of information about the possible effects to variables.

Step 2: Measure Responses Quantitatively

Simply stating pass or fail is not enough to prove the effectiveness of the strategy being utilized. There is a need to create quantitative related response method to measure the quality of a product.

Step 3:  Reduplication or replication of procedures may give chances to estimate responses more accurately. In some cases, experiments may be run randomly and it will help identify the factors that directly affect variables.

Step 4: Some effects may be changed or altered depending on the extent of its influence to the variables. Some experiments can be divided to see changes or possible outcomes or the significant impacts it may bring.

Step 5: Application of experiments must be done in a chronological manner to see any pattern that may occur. It is important to be keen and observant at all times and verify the results using tools of validation.

Conclusion

Design of experiments is a practical approach to for exploring opportunities in analyzing the system. It has many applications that are proven effective and efficient for information gathering. It also uncovers relationships among the different variables involved in the process. While many experimental designs are accessible and can be carried out, Designs of Experiments is the most systematic procedure to be executed under controlled conditions, in order to discover the unknown. It attempts to describe or explain the variation of process or information associated with the experiments. Its main concerns are the establishment of validity, reliability, and replicability. These concerns can be addressed by carefully choosing the predictor, reducing the risk of measurement error, and ensuring that the documentation method is sufficiently supported by information and other details.

Properly designed experiments will be of great help in achieving profitability and stability of the company. Technological and scientific advances will help develop the existing overall systems and improve its quality.
