What are the main barriers when performing a design of experiment in continuous improvement projects? How can these barriers be overcome? While performing any kind of design of experiment in continuous improvement projects usually could range from minor to major barriers. One of the major ones could be the budget allocated which may or may not be enough for the experiment, and could lead to the project manager going over budget if it requires more than expected. There may not be enough resources to carry out these design experiments which could use up extra time of existing resources and cause a delay in overall timeline for the continuous improvement project. Another barrier could be the fact that stakeholders are not providing enough backing for the design experiment which could delay the process in waiting for approvals from them as well. Certain training programs may be required if employees are trained in the new and therefore that would lead to additional cost and time spent for the continuous improvement project. My company is built on the foundation of innovation and therefore believes in design experiment being an integral part to growth, specifically when it comes to continuous improvement projects. What is the difference between main effect plots and interaction plots? Why are they both important? One must not confuse main effect plots and interaction plots. They are different in the following ways - interaction plots help you determine the nature of a variable which depends on another, whereas main effect plots serve more as a way to find the average outcome for the value of each variable. They are important because they help determine the importance of the variables and their results and also how to prepare for the behavior of the variables when dependent on others, to save time in the process. ------------------------------------------------------------------------------------------- 1. What are the main barriers when performing a design of experiment in continuous improvement projects? How can these barriers be overcome? There are various barriers to the continuous improvement process in an organization. One of the challenges experienced in performing a design of experiment in continuous improvement projects is the upper management's lack of support and leadership. This may include the lack of commitment or poor communication skills by the management to the experimenting team, which leads to low motivation. It may also include a lack of support by the management not allocating adequate resources such as finances and personnel that would support the design of the experiment. Another barrier encountered is the lack of support by employees. It is experienced when employees are not open to change, and therefore, the way they can express what they feel about the design of the experiment is through resistance (Tanco et al., 2009). Such may stall the experimenting or make the projects lack in terms of timelines. Another barrier experienced is the lack of skills and knowledge in the new project. Training employees to expand their knowledge and skills is vital to prepare them to handle continuous improvement processes. 2. What is the difference between main effect plots and interaction plots? Why are they both important? The main effect plot is a graphical tool that shows the average outcome for each variable's value in statistics. It is important because It combines the effects of other variables as if all variables are independent. On the other hand, the interaction plots. On the other hand, the interaction plots are also a graphical tool that illustrates the effects between variables that are not independent (Castaldi et al., 2017). Therefore, the main effect is the effects of one of the independent variables in a value. In contrast, the interaction effect is experienced if there is an interaction between independent variables, which affects the dependent variable. The interaction effects are useful because their presence in a survey helps researchers learn how two or more variables work to impact the dependent variable.
